I know more than I care to about all that jazz, I spent 11 years as an auto tech doing that almost once a day if not more, we had a spray bottle full of soapy water. It's worth the 4 dollars a piece to not do that ever again and be done with the whole situation in 2 mins!
If I spend 15 mins getting soapy water and sponges and then dealing with the mess, and then patching it and yadayada that's 26 cents a minute, a cheap price to pay to for 15 mins of time!
