So, it's nearly Christmas and as the weather fairly dry yesterday I took the oppotuinity to give the bike a clean and re-apply the ACF for the next 3 months or so. Muck-off works OK to remove most of the loose dirt with no agitaion. Another spray with Muc-off and a a little work with a plastic bristled wash up brush and the bike is clean, leave it in the workshop to dry of in front of the workshop blower heater and then a quick spray round with the cheap spraygun.
Job done.
