Use to be a cracking coin op one at the top of my road could wash the bike for 20p
It'll be fine fella. I tend to spray mine with Muckoff first and leave it a while to work its magic.Just don't blast the shit out of the radiator and bend the fins. Try and avoid greased pivot points - headstock, swing arm pivots, wheel bearings etc. Apart from that crack on.
Muc - off will take the Acf50 off...
