Spot free washing.Impossible ?NO

[bmwman53]

Got 4 black cars.Bought the CR Spotless commercial filter system and a karcher 1600 psi pressure washer.Washed my 7 and my 5 (black ) and guess what.No Spots.I does work.Well worth the money.Always had to wipe down my cars especially the black ones.But not now

nice , i have the Mr.Clean autodry system, works on the same priciple as your setup , but i bet a bit cheaper, however the filters dont last as long as i would like. the first few washes turn out amazingly.

any pics by the way?
