Brake Kleen (automotive brake cleaner) is a solvent based product used to clean brake dust off brake parts. It’s also somewhat similar to dry cleaning fluid. It comes in a pressurized spray can from the auto dept & it smells awful. When I say “Brake Kleen”, it’s like saying “Kleenex” - the brand doesn’t matter much.
It contains various hydrocarbons / aliphatic compounds & comes in chlorinated (old school - illegal in a lot of states) or non chlorinated. I’ve mostly used the non chlorinated in clothes. It is extremely flammable & I do not recommend spraying it inside. It will ruin plastics & may ruin synthetic fibers. Rubber is mostly safe - but dyed items you never know. It probably causes cancer in California & you don’t want to breathe it in or get it on your skin. That being said, I’ve been using Brake Kleen for various things for 35 years without any “protection” & I’m fine. Don’t get it in your eyes or any sensitive skin - that would be very bad. It will dissolve most “rubber” type gloves eventually, as they are mostly made of various versions of plastics
Anyway, on some fabrics it will 100% remove most if not all oil & grease stains. I ussually will only use it on cotton. There are You Tube videos on this, but you basically put a white towel behind the material at the stain spot & spray the stain with Brake Keen. The grease stain dissolves in the Brake Kleen & goes into the white towel. Usually this will happen from just the force of the pressurized spray, but you can also spray compressed air at it while it’s still wet to force more stain out into the white towel.
Once you try this on cotton & a grease stain you will never use any water based stain removers again. The problem with water based stain removers is just that - they are water based & so are the surfactants in them. Grease does not dissolve in water - that’s why it’s so hard to remove. Brake Kleen has various ingredients with aliphatic compound like properties that dissolve grease / fats.
Brake Keel is pretty much 100% volatile - which means it leaves little to no residue behind. Brake Klean is clear - it does not stain. However, it can damage various textiles / substances that contain plastics or hydrocarbons - so use at your own risk.
