I`d appreciate any suggestions on how to clean trim and bumpers on a Volvo XC-90. I was able to remove wax stains with GR-40 Trim Cleaner using a firm toothbrush, but it took 3 applications to remove the stains completely. The remaining bumpers and trim have this brownish film on it, which I think is just grime that is baked on. GR-40 can remove it, but I prefer not to scrub it 2x-3x. Not much success with Magic Eraser either.



I`m hoping there is a product that will make it easier and will not harm or discolor the finish. If not, I guess I`ll have to roll-up my sleeves and put the brush to the finish. Larger brush of coarse.
