Detailed Product Description

Safely Remove Metal Stains From Pools!

Stainfree is a 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.

Details:

  • 100% citric acid
  • Safely removed metal stains from pool liners and finishes
  • Effective on all pool surfaces- works great on steps
  • Compatible with all sanitizer systems

Directions for use:

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, CYA below 50ppm, 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 from working as designed.)

Surface Staining: If the surface is stained, add 1lb of Stainfree per 10,000 gallons as close to the stained area(s) as possible with the pump off overnight.

Water Discolouration: If the entire body of water is discolored, put the pool on recirculate, add 1lb of Stainfree per 10,000 gallons to the pool water evenly around the edge. 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 evenly to the pool around the edge at a rate of 33.9oz per 20,000 gallons.

With the pump still on, vacuum the pool walls and floor 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 DE

Test 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.

Do not swim until stain procedure is complete and normal chlorine residual is established.

Customer Reviews

I've had a pool for 20 years and this is definitely the best product I've come across. My walk-in pool stairs were brownish and stained which I thought was from the age of the pool....never thought a product could make them new again. The product worked instantly within a few minutes; I now have white clean pool stairs again. Pool looks great.

I have iron issues and I tried a lot of stuff. My pool had brownish stains. This product is awsome!!! It's basically ascorbic acid (Vitamine C) that reacts with iron oxyde.
