I fell in love with the TW platinum car wash ( $4 for gallon and 1/4) that I found at Odd Lots. I probably should have bought more when they had it because they are all gone. I love bargains, if I can find a $4 soap that rivals a $15 soap, I'm in heaven. I've tried Meguairs GC, Black magic car wash, Eagle one car wash, P21s car wash, and several others that were all pretty good. But none of them really impressed me as much as that $4 TW Platinum.
