Description
 
Sodium Persulfate is a good replacement for Ammonium Persulfate. Like Ammonium Persulfate crystals, they are used as an alternative to the traditional ferric chloride to produce a cleaner copper etchant solution. Mixed product must be stored in a ventilated container.

Dilute crystals slowly into 4 liters of water using a glass, plastic or stainless steel container. Stir until completely dissolved. To make less than 4 litres, dissolve 250 grams per liter of water.
