The hot air brush — also called a blow dryer brush, volumizing brush, or rotating air brush — has become the most popular hair-styling shortcut in Montreal homes over the past five years. The Revlon One-Step Volumizer leads Canadian sales by a wide margin, the Dyson Airwrap holds the premium tier, and a range of Conair, Remington, and T3 models fill the middle. What unites them all: a combination of heat, airflow, and bristles that traps hair, product residue, and lint faster than almost any other styling tool.
Cleaning a hot air brush takes about 5–10 minutes and needs to happen regularly. In Montreal's summers (July–August relative humidity 70–85%), people apply more serum, cream, and anti-frizz product to manage the humidity — every application leaves residue on the barrel and bristles. In Montreal winters (November–April RH 20–35%), static electricity charges the barrel surface, attracting and holding fine lint and dust. Year-round, broken and shed hair wraps around the barrel bristles and can pull and snag if left to accumulate. If the tool has a ventilation grille or filter (as all blow dryer brushes do), lint inside that grille is a fire hazard — the same reason you clean your regular hair dryer's filter.
This guide covers how to clean a hot air brush properly: how to remove hair from bristles, how to clean product buildup from the barrel, how to maintain the filter and grille, and what to do for specific models including the Revlon One-Step, Dyson Airwrap, Conair InfinitiPro, T3 Airebrush, and Remington Pro Blow Dry.

Why You Need to Clean Your Hot Air Brush Regularly
Hair buildup wraps around the barrel bristles with every use. Over time, old, broken hair caught in the bristles transfers to your clean hair during styling — the opposite of what you want. In Montreal apartments with forced-air heating systems, shed hair accumulates faster because the air circulation keeps it airborne until it lands on your styling tools.
Product residue from heat protectant sprays, serums, mousses, and hairspray dries onto the barrel surface at the tool's operating temperature (typically 160–210°C). At those temperatures, silicone polymers in smoothing serums and dimethicone in conditioners partially polymerize onto the barrel, turning into a sticky film that attracts more product with each use. Montreal summers accelerate this: the humidity causes users to apply 2–3× more anti-frizz product, which deposits proportionally more residue.
Filter blockage is a safety issue. Every hot air brush has an air intake grille — usually on the handle end — that draws room air across the heating element. Lint, hair fragments, and dust accumulate on this grille over time, reducing airflow. Reduced airflow means the motor works harder and the heating element runs hotter. In the worst case, the lint can ignite. Quebec fire-prevention guidelines recommend cleaning small appliance filters every 3–6 months. With Montreal's dusty winters (forced-air heating circulates dust through the apartment), aim for every 3 months.

What You Need
- Rat-tail comb or fine-tooth comb (for removing hair from bristles)
- Small soft-bristle brush (old toothbrush or a makeup brush)
- Microfibre cloths (2 — one damp, one dry)
- 70% isopropyl alcohol (IPA) — available at Jean-Coutu, Pharmaprix, Walmart, Canadian Tire
- Cotton swabs
- Small lint brush or vacuum with brush attachment (for filter)
- Mild dish soap (optional, for very stubborn product residue)
Do NOT use: acetone/nail polish remover on plastic barrels (dissolves the coating), abrasive pads (scratches the barrel and bristle base), water spray or submerging (electric motor), WD-40 or silicone spray (leaves a residue that attracts more lint).

Step 1 — Remove Hair from the Bristles
This is the most time-consuming part but the most important.
1. Unplug the tool and let it cool completely — at least 20–30 minutes. Never clean while hot. 2. Use a rat-tail comb (the thin-pointed end) to slide under the wrapped hair around the barrel. Work from the base of the bristles outward. A wooden skewer or a fine-tooth comb works equally well. 3. Slide the hair off in strips — work around the barrel in sections rather than pulling everything at once, which risks bending bristles. 4. For very tightly wrapped hair, use small blunt scissors to cut the hair parallel to the bristles before combing it out. Cut between rows of bristles rather than across the tips. 5. Finish with a dry microfibre cloth — wipe the entire barrel to pick up loose fragments.
Montreal tip: During peak shedding seasons (autumn, when hormonal shifts increase hair shedding, and early spring after the dry winter), Montreal residents often see significantly more wrapped hair on their hot air brushes than expected. Weekly removal is realistic for thick or long hair.

Step 2 — Clean Product Buildup from the Barrel
After hair is removed, address the product residue on the barrel surface and between the bristle rows.
1. Dampen a microfibre cloth lightly with 70% isopropyl alcohol. The cloth should be damp, not wet — no liquid should drip. 2. Wipe the barrel surface in short strokes. IPA dissolves most dried serum, heat protectant, and silicone polymer residue without damaging the barrel coating. 3. For stubborn buildup between bristle rows: dip an old toothbrush in a small amount of IPA and gently scrub between the bristles in the direction they grow. Work from the base out to the tip. 4. For very heavy, baked-on product (common on barrels that haven't been cleaned in months): mix a small amount of mild dish soap with warm water, apply with the toothbrush, scrub gently, then immediately wipe away with a barely-damp cloth. Ensure no moisture reaches the vents or the motor housing. Follow with a dry cloth. 5. Wipe with a clean dry microfibre cloth to remove all alcohol or soapy residue.
Do not apply IPA to the grille/vent area — the alcohol vapour near the heating element can ignite when the tool is next used. IPA is for the barrel surface only.

Step 3 — Clean the Filter and Air Intake Grille
Every hot air brush draws air through an intake grille, typically at the end of the handle or along the barrel. This is where lint and hair accumulate as a fire hazard.
1. Locate the grille — usually a perforated plastic or metal disc at the handle end, or a series of slots along the barrel. 2. Use a dry toothbrush or a small lint brush to brush accumulated lint off the grille surface. Work from the outside edges toward the centre. 3. For heavy lint accumulation: use the brush attachment of a vacuum cleaner on low suction, held flush against the grille. This removes embedded lint that brushing alone won't reach. 4. Wipe the grille surface with a dry microfibre cloth to remove any remaining debris. 5. Check for blockage — hold the tool up to a light and look through the grille into the air intake channel. You should see light passing through. If the channel is blocked, use a cotton swab to clear it.
Montreal winter tip: Montreal forced-air heating systems circulate particulate matter through the apartment from November through April. If you heat with a gas or electric forced-air furnace (common in NDG, Plateau, Côte-Saint-Luc, TMR triplexes), clean the filter every 6–8 weeks in winter, not just every 3 months.

Model-Specific Notes
Revlon One-Step Volumizer (RVDR5222 / RVDR5274N / RVDR5292)
The most popular hot air brush in Canada, available at Canadian Tire ($30–50), Walmart ($35–60), Pharmaprix, and Amazon.ca. The barrel is coated in a matte finish that shows product buildup clearly.
- The filter grille is at the handle end — clean it monthly.
- The nylon round bristles are fairly forgiving but can melt if you try to clean them with straight acetone — stick to IPA only.
- The RVDR5292 (One-Step Styler) has a longer barrel that accumulates more wrapped hair — remove weekly if you have thick or long hair.
- Revlon does not recommend submerging any part of the One-Step.
Dyson Airwrap Multi-Styler
Available at Sephora (Sainte-Catherine Ouest, Place Montréal Trust, Carrefour Laval, Quartier Dix30 Brossard) and Best Buy for approximately $700 CAD.
- The Dyson Airwrap uses a Coanda effect to attract and wrap hair — it does not have a traditional bristle barrel. Cleaning is different: use the cleaning brush included in the kit (or a soft toothbrush) to dislodge debris from the filter cage at the base of the handle.
- Filter cage cleaning: Remove the filter cage by twisting counterclockwise. Brush away lint with the cleaning brush. Replace the cage before use. Dyson recommends monthly cleaning; in Montreal winters, do it every 3–4 weeks.
- Attachments: The smoothing brush attachments (the Pre-Style Dryer, Smoothing Brush) have bristles and a barrel — clean these the same way as the Revlon One-Step: comb out hair, wipe barrel with IPA-damp cloth.
- Never use water to clean the filter cage — moisture inside the handle can damage the motor.
Conair InfinitiPro Hot Air Brush (BC600 / CB9000)
Available at Canadian Tire ($40–80) and Walmart. Similar construction to the Revlon One-Step.
- The filter is at the handle base — clean monthly.
- The CB9000 rotating barrel spins; remove the rotatable barrel section before cleaning for easier hair removal.
- IPA is safe on the barrel surface; avoid getting it into the rotation mechanism.
T3 Airebrush Duo Interchangeable Blow Dry Brush
Available at Sephora for approximately $200–280 CAD.
- The interchangeable head system means detach the head before cleaning — this gives better access to both the barrel bristles and the handle's air intake.
- The barrel is coated in a T3 SoftAire ceramic coating — use only a damp microfibre cloth (plain water or very dilute IPA). No abrasive toothbrush on the ceramic.
- Filter grille at the handle: brush monthly.
Remington Pro Blow Dry Styling Brush (CB7480 / CB97)
Available at Canadian Tire and Walmart ($40–60 CAD).
- Standard round-barrel construction — follow the general cleaning steps above.
- The CB97 has a ceramic-titanium barrel — IPA-damp cloth is safe.
- Filter at handle end: clean every 6–8 weeks.

FAQ — Cleaning a Hot Air Brush in Montreal
Q: How do I get hair out of my Revlon One-Step without damaging the bristles?
A: The safest method is a rat-tail comb — use the pointed end to slide under wrapped hair at the base of the barrel, then lift and slide outward. For very tightly wrapped hair, use small blunt-nose scissors to cut the hair parallel to the bristles (cutting between rows, not across the tips), then comb it out. A wooden skewer or toothpick works well for individual strands caught between bristles. Never yank hair out forcefully — this risks bending or snapping bristles, which can then snag your hair during future styling.
Q: Is it safe to use isopropyl alcohol on my hot air brush barrel?
A: Yes, 70% isopropyl alcohol on a damp (not wet) microfibre cloth is the recommended method for cleaning the barrel surface of most hot air brushes, including Revlon One-Step, Conair InfinitiPro, and Remington Pro models. Apply the IPA to the cloth, not directly to the tool. Avoid getting IPA near the ventilation grille or air intake, as alcohol vapour near the heating element can ignite briefly when the tool next heats up. For Dyson Airwrap attachments, use a barely-damp cloth with plain water for the main barrel surfaces. For T3 ceramic barrels, use water or very dilute IPA only — no concentrated alcohol.
Q: My hot air brush smells like burning after I clean it. Is that normal?
A: A faint burning smell after cleaning is often residual IPA on the barrel evaporating when the tool heats up — this passes after 30–60 seconds and is generally harmless. A stronger or persistent burning smell indicates one of three things: (1) product residue that wasn't fully removed and is burning off; (2) lint inside the filter that is overheating; (3) a motor or wiring issue unrelated to cleaning. If the smell is strong or accompanied by smoke, turn the tool off immediately, unplug it, and do not use it until you've inspected and cleaned the filter thoroughly. If lint is not the cause, contact the manufacturer.
Q: How often should I clean the filter on my hot air brush in Montreal?
A: Every 4–6 weeks is the general guideline, but Montreal winters (November–April) push this to every 2–3 weeks. Montreal forced-air heating systems circulate particulate matter and fine dust that accumulates on the filter faster than in milder climates. If your apartment has forced-air heating with a gas or electric furnace (common in NDG, Plateau, Côte-Saint-Luc, Côte-des-Neiges, and TMR triplexes), check the filter every time you do laundry — if the dryer filter is visibly full, the hot air brush filter likely is too.
Q: Can I wash my hot air brush with water?
A: No — hot air brushes are electric tools with internal motors and heating elements. Submerging or running water over them is a shock and fire hazard. The only safe water-related cleaning is a barely-damp cloth (wrung out so it's almost dry) on the barrel surface for product residue, with the tool unplugged and completely cool. No part of the tool should have standing water on it after cleaning. Dry thoroughly before plugging back in.
Q: My Dyson Airwrap filter cage won't click back on properly after cleaning. What's wrong?
A: The Dyson Airwrap filter cage is removed by rotating counterclockwise and replaced by aligning the tabs and rotating clockwise until it clicks. If it's not clicking, check that the cage is clean and the rubber gasket around the edge is seated properly — a compressed or misaligned gasket can prevent the cage from seating. Also confirm you're rotating the correct direction; the cage has an arrow indicating the removal direction. If the tabs on the cage are cracked or broken from being forced, Dyson Canada offers replacement filter cages through their website or through Sephora's service desk.
