So I have a eg6 that recently got painted outside, rear trunk, & engine bay. I was wondering what I could use to clean up the trunk, not that its dirty but after time dust will pill up & look dirty, & also to clean the engine bay. I tried searching the web with answers but didn't find much but I did come across something called Detailer's Pro Series waterless auto wash. Heres a link below

DP Waterless Auto Wash lets you wash your vehicle without water! Waterless car wash

If it can be used all over the outside of the car why not for the bay & trunk area? Has anybody ever tired this product before?
