STAINfree is an all natural citric acid product that removes metal staining on pool liners and finishes. STAINfree is ideal for treating staining on all pool surfaces and is compatible with all sanitizing systems. Use Natural Chemistry's METALfree and you have the ultimate 1-2 combination for stain fighting!Note: Operating the pool for a couple of days without chlorine can create an algae concern. Follow your pool dealer?s recommendations on steps you can take to protect your pool from algae during this metal stain removal process.Balance pool water chemistry before using STAINfree: pH:7.2-7.6, Alkalinity: 80-120ppm, Calcium Hardness: 200-400ppm, Phosphates: below 100ppb Note: Stain removal products work best when the pH is on the lower side of acceptable range (7.2)Important: Before starting the metal stain removal or water discoloration process (step 4), a pulp based filter aid must be added to cartridge and sand filters. DE filters must be properly charged.Lower chlorine level to 1ppm or less (A high chlorine level or adding oxidizing agents during the process will prevent STAINfree Extra Strength from working as designed.)Surface Staining: If the surface is stained, add 1lb of STAINfree Extra Strength per 10,000 gallons as close to the stained area(s) as possible with the pump off. Keep the pump off overnight.Water Discoloration: If the entire body of water is discolored, put the pool on recirculate, add 1lb per 10,000 gallons of STAINfree Extra Strength around the perimeter of the pool and let the circulation run for one hour. After one hour, shut the pump off and let sit overnight.Before turning the pump back on, brush the pool walls and floor thoroughly.Turn the pump back on and add METALfree around the perimeter of the pool at a rate of 33.9oz per 20,000 gallons.With the pump still on, vacuum the pool surfaces very thoroughly.After vacuuming, clean filters: Sand filter- backwash for at least 3 minutes and then rinse for 2 minutes Cartridge filter- clean filter and filter tank thoroughly DE filter- backwash and recharge with DETest and rebalance water. DO NOT SHOCK THE POOL FOR AT LEAST 1 WEEK.Note: If chlorine level is low, add small amounts of chlorine. Do not exceed 2ppm. For salt generator pools, a granular shock is recommended instead of turning the generator to its boost (superchlorinate) function after the recommended 1 week.Use METALfree as a weekly maintenance to prevent future metal staining. Apply 4oz per 10,000 gallons once a week.Do not swim until stain procedure is complete and normal chlorine residual is established.

Highly Recommend

Verified purchase

Worked like magic to remove stains from the bottom of our saltwater pool without issue to alkalinity, chlorine or other levels and is safe for swimming much more quickly than other options. Highly recommend this product.

UNBELIEVABLE

I can't say enough about this. I read reviews on other sites about this, and found the best price here. I started on the steps this afternoon, sprinkled just a little bit in the water, and turned around to get a "before" photo, and when I walked back, the steps were already getting white. I was shocked! This stuff is the bomb. I have just a few places left in the cove areas of the pool to clean. I need more of this.....wow!

Just works

It got the iron scale stains off of my steps and vinyl liner. Do NOT waste your money on Step Stuff. Buy this, sprinkle it in and let it sit all night with the pump off. Lightly brush the area the next day and its gone.
