How to Use Brake Cleaner (and What It Actually Does)
Brake cleaner is one of the most useful cans in any garage — and one of the most misused. Used right, it blasts grease, brake dust, and oil off parts in seconds and flash-dries with no residue. Here’s what it does, and exactly how to use it.
What does brake cleaner do?
Brake cleaner is a fast-evaporating solvent that dissolves and blasts away brake dust, grease, oil, and grime — then dries film-free so it won’t affect braking. Because it leaves no residue, mechanics reach for it on far more than brakes: chains, bike parts, metal surfaces, and any part you need spotless and dry before assembly, adhesive, or paint.
Chlorinated vs. non-chlorinated — which should you use?
Older chlorinated formulas cut fast but carry harsher fumes and handling concerns. Non-chlorinated brake cleaner is the safer, lower-VOC choice for most brake components and the person spraying it — without giving up cleaning power. BG Brake Parts Cleaner is a non-chlorinated, professional-strength formula: fast, safe, no residue.
How to use brake cleaner (step by step)
- Prep. Work in a well-ventilated area, away from heat, sparks, and open flame — brake cleaner is a flammable aerosol. Wear eye protection and gloves.
- Apply. Hold the can a few inches away and spray directly onto the greasy, dusty part. Let the solvent do the work — heavy grime may need a second pass.
- Let it flash off. The cleaner blasts contaminants off and evaporates in seconds, carrying the grime with it. Catch runoff in a rag or pan.
- Wipe and inspect. Wipe with a clean, lint-free cloth if needed. The surface dries film-free and ready for assembly, adhesive, or paint.
How to clean brakes with brake cleaner
With the wheel off and the caliper/rotor exposed, spray the cleaner over the rotor face, caliper, and pad area to flush off brake dust and grease. Let it run off and flash-dry — no scrubbing. Never spray a hot brake assembly, and keep it off rubber lines and painted surfaces where you don’t want overspray.
Safety first — always
- Flammable aerosol: no heat, sparks, or open flame. Never spray hot components.
- Ventilate. Don’t breathe the fumes.
- Protect skin and eyes; catch and dispose of runoff responsibly.
The bottom line
Brake cleaner earns its spot on the shelf because it cleans fast and dries clean. Use a non-chlorinated formula, spray it on, let it flash off, and you’re left with a spotless, dry part in seconds. For pro-strength power with no residue, keep a case of BG Brake Parts Cleaner within reach.
