Can Dexron II cause decay(rot)?


While we were changing the hydraulic oil, old oil was spilled on the car body and belts.
Can Dexron II cause decay of car body and belts? What should I do?


ATF fluid should not cause a problem on the body panels. Just wash it off with car wash detergent, then a coat of car wax.
As far as the belts, unlikely will cause significant harm. If not causing slippage you are probably okay.
