Jet washes - good or bad? Despite all my intentions of only riding in the dry, even at 1pm today with wonderful Sunshine, it's still so cold that the frost has turned to damp patches, which remain in shady areas. And as the bike is new, I can't help but take it out when I've got some time off. Fortunately I haven't seen the gritters out my way, yet. So, I've heard bad things about jet washers - that they strip the paint from your wheels and cause untold amounts of damage (despite never seeing any similar damage to our old 4x4). But then I've also seen them used in bike mags (along with steam cleaners) without trouble. So - use 'em or leave 'em alone? And are the home type pressure washers any better (Halfords / Karcher / etc) and if so, which is worth buying? As an aside, are those products like FS365 anti-corrosion spray any more useful than snake-oil?
