Matthew,
Formula for Kodak TC-3
Water 1.0 liter
Potassium Permanganate 2.0 grams
Sulfuric Acid(concentrated) 4.0 ml (add acid last while stirring
constantly)
KodakTC-1 DuPont 1-TC
To remove developer oxidation stains, and some silver and die stains.
(Dichromates are heavy metals and hazardous)
DO NOT USE TC1TO CLEAN YOUR HANDS USE TC-3
Water 1.0 liter
Potassium Dichromate anhydrous 90.0 grams
Sulfuric Acid 96.0 ml (add acid last while stirring constantly)
Use a small amount of TC-1 in tray to be cleaned, rotate tray around so
TC-1 covers all surfaces to be cleaned, then pour out and wash about ten
times with water until no more cleaning solution is visible.
TTFN
