Halloween 2029 falls on Friday, October 31 — a weekend-adjacent date that historically means double the celebration and double the cleanup. Thursday evening brings adult costume parties; Friday brings trick-or-treating for the kids and more adult gatherings after dark. By Saturday morning, November 1, your Montreal apartment has experienced at least 48 hours of Halloween activity. This guide covers the full cleanup cycle, built around the specific conditions of Montreal in late October 2029.
If you've followed the [Fall Cleaning Checklist Montreal 2029](/en/blog/fall-cleaning-checklist-montreal-2029) and the [Thanksgiving Cleaning Checklist Montreal 2029](/en/blog/thanksgiving-cleaning-checklist-montreal-2029), your home is already in good shape going in: steam radiators are running, furnace filter is fresh, and your colimaçon iron staircase received its final linseed oil treatment before the October 1–10 frost window closed. Halloween cleanup picks up where that left off — focusing on the specific stains, debris, and damage that Halloween uniquely produces in compact Montreal triplexes, condos, and apartments.

Why Montreal Halloween Cleanup Is Different
Montreal apartments face three specific challenges at Halloween that most cleaning guides don't cover:
Hard water amplifies pumpkin stains. Montreal's tap water runs at 270–300 mg/L CaCO₃ — some of the hardest municipal water in Canada. When pumpkin juice (rich in sugars and organic acids) contacts a hardwood floor that's been cleaned with Montreal tap water, the calcium and magnesium ions in the water bond with the organic compounds in the pumpkin pulp. The result: a mineral-organic crust that hardens within 12 hours and cannot be removed with water alone. Act within 2 hours of a spill.
Friday Halloween = double-night damage. Thursday Oct 30 costume parties produce the first wave — face paint transfers, fake blood, wine and cocktail spills. Friday Oct 31 trick-or-treat brings muddy boots tracked across your entryway and hardwood, Halloween candy wrappers, and the glitter-bomb aftermath of whatever costume your child wore. Plan a 2-stage cleanup: a 30-minute damage-control pass Friday evening after trick-or-treat ends (around 9 pm), and a full Saturday morning deep pass.
Road salt season begins around Halloween. Montreal's first major road salt event typically occurs between October 31 and November 15, depending on weather. If the city salts on or before Halloween night, salt will track into your entry zone on the first trick-or-treater's shoes. Your colimaçon iron staircase is sealed for winter — but double-door mat protocol should be active by October 28.

Before Halloween: Oct 28–30 Prep (30 Minutes)
Protect high-risk surfaces before the jack-o-lantern comes in. Place a cork trivet, a sheet of parchment paper, or a silicone baking mat under every carved pumpkin. Pumpkins sweat; the moisture on their underside can lift finish from hardwood or stain concrete in under 24 hours. Do this before you carve.
Set up a double-mat boot zone. Place a scraper mat (rubber bristle or coarse coir) immediately outside the door and an absorbent mat inside. Montreal trick-or-treaters shuffle through wet leaves and potentially early road salt. The dual-mat system captures 80–90% of the debris before it reaches your hardwood.
Pre-position your cleanup kit. Pull out: microfibre cloths × 4, one spray bottle with dish soap diluted in cold water, one bottle of enzymatic cleaner (Nature's Miracle from Mondou, or any pet-odour enzyme cleaner — they work identically on biological stains), a plastic scraper card, ice cubes in a zip-lock bag, and mineral spirits in a well-ventilated area.

The Jack-o-Lantern Problem: Pumpkin Juice on Hardwood
This is the Montreal Halloween cleaning issue that generates the most questions. Here's the full protocol by how much time has passed since the spill:
Fresh spill (under 2 hours): Blot with a dry microfibre cloth — never rub. Remove as much liquid as possible in the first 2 minutes. Then spray lightly with dish soap diluted in cold water (1 tsp per cup), blot clean, follow with a plain cold water rinse using a well-wrung cloth, and dry completely with a clean microfibre.
2–12 hours after spill: The mineral crust is forming. Complete the dish soap blot step above, then apply enzymatic cleaner (verify it's safe for hardwood — most are). Let sit 3–5 minutes, blot clean. For the remaining mineral residue: dilute 1 tablespoon of white vinegar in 1 cup of cold water, apply with a cloth, let sit 2 minutes, blot, dry completely.
After 12+ hours: The mineral-organic crust is set. Apply a citric acid solution (1 tsp citric acid powder in 500 ml warm water — available at IGA, Maxi, or bulk food stores) with gentle circular pressure, 10-minute dwell, blot, repeat up to 3 times. If the floor finish is lifting or the stain persists after 3 rounds, stop and book a professional — floor refinishing is far more expensive than a cleaning appointment.
Prevention wins every time: Cork trivet under every pumpkin, before you carve.

Candle Wax on Hardwood
Pumpkins with real tea lights drip wax onto floors and tables. The correct protocol:
1. Harden the wax first. Press a zip-lock bag of ice cubes directly on the wax for 10 minutes. Don't skip this step — scraping warm wax smears it deeper into the wood grain. 2. Scrape with a plastic card. A credit card or dedicated plastic scraper held at a low angle. Never metal — metal edges scratch polyurethane finish. 3. Remove residue with mineral spirits. Apply a small amount to a clean cloth (not directly to the floor), and wipe in the direction of the wood grain. Test in an inconspicuous corner first. 4. Restore the finish. Apply a light coat of hardwood conditioning oil (Bona, available at Rona or Canadian Tire) where the mineral spirits have slightly stripped the sheen.

Fake Cobweb Removal
Stretched polyester fake cobweb is one of the most tedious post-Halloween cleanup tasks. Strategy:
Dislodge before pulling. Pulling stretched cobweb embeds fibers into crown moulding crevices and popcorn ceiling texture. Use your vacuum's crevice attachment first to remove the bulk. Then use a packing-tape lint roller in a pressing — not rolling — motion on textured surfaces.
Address the static problem. Fake cobweb generates static electricity in Montreal's dry autumn air (30–40% RH indoors with steam radiators running). Before you try to roll up or ball up a cobweb, touch it with a dryer sheet to discharge the static. The fibers clump together instead of flying across the room.
Ceiling cobwebs. Use a telescoping microfibre duster to collapse the cobweb onto itself, then vacuum from the floor.

Fake Blood on Carpets and Fabrics
Fake blood is typically glycerin-based with red food dye. Two-stage protocol:
Stage 1 — Remove the bulk: Cold water blot first — never hot. Heat permanently sets protein and dye stains. Apply enzymatic cleaner (Nature's Miracle from Mondou, or equivalent). Let sit 5 minutes. Blot clean with cold water and a fresh cloth.
Stage 2 — Address remaining dye: If a reddish tinge persists on carpet, make an OxiClean paste (one scoop of OxiClean Versatile Stain Remover with just enough cold water to form a thick paste). Apply to the stain, cover with a damp cloth, leave for 30 minutes. Rinse with cold water, blot dry. Available at Pharmaprix, Jean Coutu, or Canadian Tire.
For white or light fabrics: 3% hydrogen peroxide (the pharmacy kind, not the bleach-grade) applied directly to the stain, left 10 minutes, rinsed cold. Test on a hidden seam first — hydrogen peroxide lightens some dyed fabrics.

Glitter: The Montreal Apartment Challenge
Glitter in a heated Montreal apartment is particularly problematic. Steam radiators create convection currents; forced-air furnaces blow air through every duct. Both circulate fine glitter particles throughout the unit.
Do not vacuum first. A standard vacuum's exhaust port blows fine glitter particles into the air, where they settle on every surface. If you must use a vacuum, tape a microfibre cloth over the exhaust port to catch escaping particles.
The rubber glove method for hard surfaces: Put on rubber kitchen gloves, dampen them slightly with water, and wipe surfaces using a flat pressing motion. The rubber generates just enough static attraction to pull glitter off without flinging it.
Rubber squeegee for floors: A rubber-blade window squeegee (the same kind used for shower doors) gathers glitter into a line on hard floors far more effectively than a broom or dry mop.
Final residue: Packing tape pressed (not rolled) repeatedly picks up what the squeegee missed. For carpet, this pressed-tape method is actually the most reliable technique throughout.
After heavy glitter use: Check your furnace filter within 2 weeks. Glitter-clogged filters in November reduce heating efficiency during the coldest months. A $15 MERV-8 filter is a reasonable follow-up investment.

Fog Machine and Theatrical Effects
If you used a fog machine indoors, wipe all horizontal surfaces the same night — before the glycol-water mist film dries. Dried fog fluid leaves a faint sticky residue on TV screens, glass frames, and mirror surfaces that attracts dust. A damp microfibre cloth removes fresh fog film in seconds; dried film takes an all-purpose cleaner and more passes.

Post-Trick-or-Treat Entryway Reset (Friday Evening, ~9 pm)
After the last kids come back inside, spend 20 minutes on the entryway before bed:
1. Shake the scraper mat outside. Wet leaves, mud, candy wrappers — shake it all back outside. 2. Take the absorbent mat outside. Beat it against the railing. Not a job for the hallway. 3. Sweep or dry-mop before any wet cleaning. Wet mopping over grit scratches hardwood. 4. pH-neutral hardwood cleaner. Diluted Bona or equivalent. Not vinegar, not all-purpose spray — vinegar is acidic enough to dull polyurethane finish with repeated use. 5. Check your colimaçon staircase. No linseed oil needed (season closed October 1–10), but sweep leaf debris from the ironwork and check for salt residue. If early road salt has landed on the iron steps, rinse with plain cold water before bed to prevent accelerated rust.

Bac Brun: Pumpkin Composting in Montreal 2029
Montreal's brown bin composting program accepts pumpkins throughout October and November collection cycles. Before your jack-o-lantern goes in the bac brun:
- Remove all artificial decorations: glitter paint, stickers, metallic spray, plastic stems, glow sticks, any wax drips
- Remove the candle or tea light: obvious, but the number one oversight
- Break up large pumpkins (15 kg+): smaller pieces compost faster and fit the bin more easily
- Seeds are compostable: put them in the bac brun, not the bac vert
Check [montreal.ca](https://montreal.ca) for your collection day. Pumpkin composting collection in Montreal typically runs on the normal brown bin schedule through mid-November.

When to Book Professional Post-Halloween Cleaning
If your Halloween gathering was large — 20+ people across two nights — a post-Halloween professional clean is a cost-effective investment in a city where damage deposits and lease renewals are closely watched. Key threshold: if you have glitter embedded in carpet, pumpkin-juice stains that didn't come out, or wax damage on hardwood, a professional clean is cheaper than a floor refinish or a security deposit dispute.
Approximate pricing in Montreal (before GST/QST at 14.975%):
| Unit size | Standard clean | Deep clean | |---|---|---| | Studio (up to 450 sq ft) | $120–$175 | $230–$330 | | 1 bedroom | $150–$210 | $280–$390 | | 2 bedrooms | $180–$250 | $330–$460 | | 3 bedrooms+ | $220–$310 | $380–$540 |
Book by October 28 for best availability — the last week of October fills quickly as Montrealers schedule pre-Halloween prep cleans and post-Halloween deep cleans simultaneously.
See our [Montréal deep-cleaning service](/en/services/deep-cleaning) for details and booking, or our [recurring cleaning plan](/en/services/recurring-cleaning) if you want the apartment maintained through the holiday season ahead.

Halloween Cleaning FAQ
Q: How do I clean pumpkin juice off hardwood floors in Montreal?
A: Act within 2 hours. Blot (never rub) with dry microfibre, then apply 1 tsp dish soap per cup of cold water, blot clean, rinse with a well-wrung cold cloth, dry completely. For stains sitting 2–12 hours, add an enzymatic cleaner step, followed by a 1:30 white vinegar-water rinse for the mineral residue left by Montreal's hard water (270–300 mg/L CaCO₃). After 12 hours, apply a citric acid solution and repeat up to 3 times. If floor finish is lifting, stop and call a professional — floor refinishing is far more expensive.
Q: What's the best way to remove fake blood from apartment carpet?
A: Cold water blot first — hot water permanently sets the dye and protein. Apply enzymatic cleaner (Nature's Miracle, available at Mondou), 5-minute dwell, blot with cold water. For remaining dye, make an OxiClean paste with cold water, apply, cover with a damp cloth for 30 minutes, rinse cold and blot dry. On light-coloured fabrics, 3% hydrogen peroxide works but always test on a hidden seam first.
Q: How do I get glitter out of my Montreal apartment without spreading it everywhere?
A: Don't vacuum first — the exhaust blows glitter through the air. Start with dampened rubber kitchen gloves pressed (not wiped) across hard surfaces to collect particles via static attraction. Then use a rubber squeegee to gather glitter on hard floors into a line for collection. Use packing tape pressed (not rolled) on carpets and any residue on hard surfaces. After heavy glitter use, check your furnace filter within 2 weeks — glitter clogs MERV filters and reduces heating efficiency in November.
Q: Can I compost my jack-o-lantern in Montreal's bac brun?
A: Yes — Montreal's bac brun accepts pumpkins throughout October and November. Remove all artificial decorations, wax drips, candles, plastic elements, and metallic spray before composting. Break up large pumpkins (15 kg+) for faster decomposition. Seeds also go in the bac brun, not the bac vert. Check montreal.ca for your collection schedule.
Q: My child's Halloween face paint got on the carpet — how do I remove it?
A: For water-based face paint (most modern costume makeup): cold water blot, then dish soap diluted in cold water, blot clean, rinse cold. For oil-based greasepaint or theatrical makeup: pre-treat with a small amount of baby oil or mineral oil worked in gently, let sit 5 minutes, then blot with dish soap solution. For either type, follow with enzymatic cleaner if colour pigment remains. Always cold water — heat sets pigment and dye into fibres.
Q: Should I worry about road salt tracking in on Halloween night in Montreal?
A: From October 31 onward, yes. Montreal's first major salting event typically falls between October 31 and November 15. Set up your double-mat system (scraper mat outside + absorbent mat inside) by October 28 at the latest. If salt tracks in on Halloween night, clean hardwood immediately with pH-neutral cleaner and dry thoroughly — salt combined with moisture corrodes polyurethane finish and, over time, the wood itself. For your colimaçon iron staircase: the linseed oil season is closed, but rinse any salt residue with plain cold water before it causes accelerated rust on the ironwork.
