I've been using Eagle One soap to replace to overpriced Mr. Clean soap. It's just a little thicker, but I can use it without thinning it out and have had no problems yet. Seems to do a good job. I only wish they had a generic filter out there to replace the Mr. Clean Filters. Cat I have gone to the carwash across from Greenwood Mall 3 times now and have had no signs of scratches or swirls on my black paint job. For $12 you get a full interior and exterior clean and a hand towel wipe down to finish. Just a thought if your short on time and want your baby to shine.
