(Let me state, I have nothing to do with this product) I was reading one of the bike mags, and saw an advert for this product. It is a disposable cleaning wipe, that comes in a tablet form, and when you add water, it opens up into a normal wipe. I thought it may be a bit gimmicky, but it actually does work as stated, and is biodegradable. They come in a small cylindrical tube, that can easily be hidden anywhere on a bike, e.t.c. Certainly, for those times when out on a hot day, add a bit of water, and you have a clean wipe to wipe the face off, e.t.c. One tube of 10 pieces is $2.95, or I bought 10 x 10 pieces for $20, both plus postage. http://www.purewipes.com.au/home.htm is the website.
