Ok for quite some time I've been trying to clean my truck and get rid of the acid rain spots that are left on the trucks windshield and bumper (I haven't quite figured out how to get it off the paint yet, but i think a high speed buffer will help me here). Well after hours of trying different polishes and scrubing with a brush i kinda gave up for a while, then while searching through the storage shed i found some denatured alcohol... I thought "well hell I'll give it a try on the bottom side of the rear bumper". Tried it out, and it shined!

So then i tried it on the rest of the bumper (Keep in mind, do not use on painted parts, only chrome/metal/glass) and WOW, what a difference!!! I also tried it on the windshield and WHAT A DIFFERENCE! no more crazy waterspots that never came off with normal scrubbing. Other parts I have cleaned with it are the diamond plate toolbox/rails and the front grill on my truck. I went over all of it (except the grill, its made of a diff material) with mothers chrome/mag polish and it shined right up!

DISCLAIMER : I am not responsible for any damage that the denatured alcohol causes, use this stuff in an inconspicous place first to test out. If you get any on your paint and it bubbles, it is not my fault

But dont be afraid to try it out
