Washed my car with the Karcher K3.99M which I found laying around in my conservatory from previous person who lived there
checked it all and worked fine see pics below
also stuck the small rubber pipe into some autoglym shampoo conditioner to see if it worked, didn't work at first seemed like it was clogged so I used the pressure washer to unclog it
worked a treat until the shampoo ran out haha, finally I used the polish resin thing whatever its called and made it all shiny
not sure what happened to the pic
took using my Samsung GS4
Also thinking of buying a snow foam lance attachment from Halfords
