Hi all
Recently bought a cheap Top Tech pressure washer from Euro car parts as the price was very good and I needed one for all sorts of cleaning jobs. It came with a dtergent bottle rather than a snow foam lance but I gave it a go anyway with Auto Glym Polar Blast. The results were very poor, I couldn't get a good lay er of foam on the car in fact it looked like I'd just thrown a bucket of soapy water over it. Followed all recommendations etc.
So I bought a snow foam lance, not easy as the Top Tech fitting seems to be unique to them so I adapted a Bosch one. Still rubbish results and the lance sucks hardly anything out of the 1 litre bottle. I'm toying with the idea of making my own venturi but any advice in the meantime would be welcome.
