Been reading this thread with interest, may give it a go. I have been using a pressure washer for a while, don't think you will do any damage as long as you don't get too close with the water jet.<br />Steve.
Quick update; tried some of the Chemical Guys Honey Dew Snow Foam today<div><br></div><div>Amazing. Super easy to use for great results!</div><div><br></div><div>Thanks all for the advice</div>
Tried Advanced pH Neutral Snow Foam. <br />I pre rinsed then applied foam with my Karcher<br />Great foam up which I left on for just 5 mins. <br />I gently agitated with my microfibre mitts<br />Then rinsed off with the Karcher (used at a distance so pressure wasn't too much)<br />Dried with a microfibre cloth.<br />Great results even on my black alloys and whole thing took me 25minutes.<br />Very pleased.
