[alt-photo] Re: Question for Platinum/Palladium printers

[clay at clayharmon.com]

First bath of disodium EDTA mixed to full saturation - about 1 heaping tablespoon per liter of 100 degree water
Two baths of working strength Hypoclear with 1 tbsp of tetrasodium EDTA per 2 liters
Wash for ~20 minutes at a very low rate

For stubborn papers like BFK on occasion I wlll heat the first disodium EDTA bath to 130 or try 2% phosphoric acid or 1% HCl, then the hypoclear
