EDTA Tetra Sodium (B+S Clearing Agent) 500gm

EDTA Tetra Sodium is a safe, non-toxic clearing agent. It is great for use with Ammonium Citrate developer. This powder is added to water. Use 2-3 tablespoons to 1 quart of water, and less will just take longer to clear, more will clear faster.

If using Potassium Oxalate developer, we recommend a mixture of EDTA and Sodium Sulfite.
