My experience is that as long as it's not detergent, not much stops the ACF50 working. My only concern with reapplying ACF50 would be wiping in the grit that's already on there. As long as you just spray more on you'll be fine. I wouldn't go wiping the bike once it's covered in crap.

I tend to apply the ACF50 in November and then come January when the bike looks a total state, give it a really good clean and then reapply ACF50 to a clean, dry bike and that'll see me through to the next big clean in spring.

I think when you see how much crap sticks to ACF50, especially if it's been applied a bit thick, you'll be itching to give the bike a good clean well before spring. :)

If you live anywhere near London, and feel like treating your bike, try these guys - http://www.mo-clean.com/

I've never tried them myself, but I know people who are very keen. And no, I don't have any interest in the company :)

Some great feedback on here, but just wondering where everyone purchases their cleaning/protection products from? And how much we are looking at for them, the ACF50 sounds great, but first time I have ever heard of that.

Oh how my Tenere always relishes a wash, and should be washed more poor dirty mitten! If anyone has any more funky tips etc on cleaning a Tenere, especially around the engine, they will be gladly received.

I was recommended acf50 on here. Very expensive but I think it's a much better investment than any other thing u can buy for your bike other than a garage.
