I can't see a problem with it, as long as you use rinse water and not soap...i purchased an extra UIM a while ago, took it to the car wash and sprayed the h*ll out of it, inside and out. it looked new, as far as I could see, and seemingly has no problems (although i never installed it). Will I need a new LIM UIM gasket for ust an UIM cleaning? I don't think I have the technical experience or tools to do the lower. What about a new TB UIM gasket? STOP, DON"T SHOOT, I'm going to the how to now, but wanted to reply...thankx
