I thought I'd post up some results after trying the "two bucket wash" method. I'm new to detailing, I've always enjoyed cleaning my cars and keeping them looking as good as possible. It is only recently that I've started getting into proper detailing though. It's early stages where I'm considering what to buy but the instant changes I made was the two bucket wash. I wasn't too sure quite how effective it would be and how much grit would be picked up so when I emptied the buckets I decided to catch what was left and I took a picture. This is what was left in my "wash" bucket, the water was a lot cleaner after washing I noticed, it's usually black but this time you could see through it. This was what was left in my "rinse" bucket. The water was filthy and I was surprised how much grit was actually left in it! This was just one wash... I was surprised by the results so for anyone who thinks Two bucket washing is pointless... It's really not! Now I dread to think of those people who chuck the last bit of water over their car as they've finished washing it!!!
