Stepped my foam game up. Got a pressure washer and a foam lance attachment for it. Real exciting ...this is really fun to use. Tried it out on my camaro. Just wanted to try it out real quick...didn't even break out the buckets. Let foam dwell for 5 minutes then rinsed with pressure washer. worked great. Car hadn't been washed since last fall and came 99% clean. 1% was some tough road tar and the wheels which I didn't scrub.
