I had to remove tree sap from my C6 corrector plate recently (only left it for a few minutes - damn!).

A friend of mine is a conservation scientist and has to deal with all manner of difficult but extremely delicate (and expensive) cleaning issues. They had just spent 4 months cleaning a Roman vase....

He recommended distilled water with no additives. It worked a treat. However, as others have said it's vital that anything abrasive - dust, grit etc is removed first, and very little pressure is applied. The coatings on modern lenses and glass are not water soluble and will not be harmed by this. Soap, detergents and wetting agents can leave a residue, but again this won't harm your glass.

As had been said, if you don't need to, don't clean it. Hope this helps.

Thanks for the heads up, James.

I've just put mine on charge. I think I've been really lucky with mine so far. They last for weeks and weeks with my CG5, but then I don't think it draws much juice - non goto version.

Having said that, the charge light never goes out and shows fully charged, even if left on for 24hrs.

Camp mats are available in black - saves painting them.

I wonder if this would be any good?
