Those cheap jetwashes aren't very powerful John. It's the much dearer ones from the specialist jetwash manufacturers that are the problem, they can strip paint down to metal instantly and even break glass. However, I can't see your Twist, used on the road, ever needing anything other than a light swabbing with a cloth or sponge and lukewarm water with a drop of washing up liquid.

Their finish is excellent, and after being treated like that for nearly four years, only a few days ago someone asking about it thought I'd just bought it new.

Those mountain bikers are probably making the mistake of letting the mud dry hard on their bikes, always best washed off when fresh.
