Jack's Magic O2 Safe Shock Stain Solution #3 can be used as an acid wash pretreatment, making tough copper stains much easier to remove. A non-chlorine shock (but not a persulfate compound), O2 Safe Shock yields more than 12% active oxygen (3 times more oxygen than persulfate compounds).

Please Note: Not recommended for chlorinated pools, but ideal for biguanide, ozone, and ionization systems.
