I used the dryer sheet trick, as per everyone, to get ride of bugs. I was displeased when I found an ass-load of fine scratches in the paint. It was on black paint if that matters, and i used cold water to soak it not hot.
This maybe embarassing to most guys here, but just go to the store and buy a pair of pantyhose. The cashiers might look at you like you're a crossdresser but I tell them it takes bird poop off of my car really well.
Say! How About a Safe Scrub! Floridians know all to well about Love Bugs and what they can do to a car's paint! (Yikes)....This is a product I swore I would never use....but I broke down and bought one...tried it on my wife's vehicle first and VIOLA!! It saves a ton of time on cleaning up bugs and NO SCRATCHES! I was impressed, I was amazed, I was bug-less and pleased!
Bugs are a pretty bad problem around my area. I just use a can of Tuff-Stuff upholstery cleaner. Just spray it all over the bugs on the car and let it sit for about 2 minutes then just rinse it off and the bugs just come right off. It won't scratch your paint and it's conveniently sold at wal-mart for a very inexpensive price.
