Can I use 80w-90 gear oil to clean my new rotors instead of buying a can of brake cleaner?

Why do you want to ';clean' them?? Wire brush for rust, and soap and water for the rest works just fine! Oil will leave some residue that has to burn off before it lets brakes operate right! When repalcing brakes on my cars, I just stand back and ';hose the area down good with water';. This keeps the dust from being inhaled, and gets all the ';powder off most things, - the wheels I use soap and water to get stuff off, (as it removes accumulated grease too)!Can I use 80w-90 gear oil to clean my new rotors instead of buying a can of brake cleaner?
If you do not get all of the oil off, including the very thin film that is difficult to clean off, you will find that you may have poor brake operation.





I recommend that you use the commercial brake cleaner to clean the rotors.Can I use 80w-90 gear oil to clean my new rotors instead of buying a can of brake cleaner?
Sure, go ahead. It won't hurt a thang!
ABSOLUTELY NOT.Putting gear oil or any thing similar will coat them and when you put the caliper back on with the brake pads in it the oil will contaminate the pads and render them useless HENCE NO BRAKES.You can buy a cheap can of brake parts cleaner at a parts store like auto-zone just buy the store brand.I believe the cost will be under two-three dollars and since it's the same chemical as the brand name ones you get the same results CLEAN DRY BRAKE ROTORS even if they are brand new with the anti corrosion coating on them as ANY BRAKE CLEANER will dissolve it.
dah
are you joking? no you cant do that the purpose of using brake cleaner is to clean off the oil that is on the rotors that the factory uses to keep them from rusting , oil on your break pads is a bad thing brake cleaner is the only way to go because it dries residue free.
if the auto parts store is closed and you cannot get brake cleaner,you can use dish soap and hot water in a pinch,after washing them,dry good with a towel,
I would say not, why would you use oil on it you want the friction to stop you
Wholy cripes NO. Today replacement brake rotors come with a water soluable grease on the surfaces. Wash then off with dish soap in a large paint pail.





We do brakes every day and almost always cleaning instructions are inside. I almost forgot, cheap off-shore rotor boxes tell you nothing. Not even how bad the product you just purchesed actually is!
hell no. your trying to get the grease OFF, WD-40 .RUBBING ALCHOL , or somthang like that will work. but no oil , gear lube or that kind of stuff will not work.
wouldn't suggest it
oil, on a device that works by friction????





NO, don't be cheap, buy the cleaner. Oil on a rotor will make your brakes fail!
