Re: [ATM] Fine scratches during polishing - Cures?

[Mark Cowan <toolontop@yahoo.com>]

One more thing to watch out for in cleaning - I've
/scratched/ a mirror with a stream of water from our
otherwise execllent city water system (mountain source
thru sand filtration, used by chip manufacturing with
no processing) - sand comes out of the tap on occasion
and can make it through the faucet screen.

Lacking that, the water here is so clean mirrors often
dry cleaner than from some distilled batches.

Cheers,
