to wash their bike

strip paint and rust off old shit !

which washer did you use it with ?

it says for any K series karcher pressure washer – mines a K2 but i cant help but think it might be a touch weedy to have any effect – rusty chassis needs welding and painting – amongst other projects !

although the cynic in me thinks its probably a pile of pish

I bought one a few years back to use with and old 2 series pressure washer (fairly basic one).
I was trying to clean up an old sandstone fire surround….didn’t work very well on that….just made a lot of mess (I was inside though!!)
Never tried it on old rust or paint but it did what it was supposed to do ie. fire a jet of sand and water at whatever you pointed it at……havent used it since…..
