Re: Cleaning glass for dryplates



 
       The guys the clean  lenses use 190 proof grain alcohol and possibly some distilled water..... Bon Ami is the same as Rottenstone  sold in grocery stores.... It is a fine  grade pumice that will not scratch the glass and is actually used as one of the preliminary steps in polishing glass  prior to  cerium oxide as the final step...........

Rottenstone (available in hardware stores) mixed with alcohol to make a slurry. Wipe really well and then wipe off the sludge with a lint free cotton cloth such as an old T-shirt.

I'm searching for glass cleaning concoctions for preparing dry-plates, any suggestions? Up till now, I've been using Sodium Carbonate 1tbsp in hot tap water and kitchen towel. This seems to work quite well, 'till the plate dries and I'm left with very faint marks caused by residual carbonate. No matter how much I rinse, I still get these marks.
