Product Specifications

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 Discoloration: 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.

Use Natural Chemistry 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.

    I used this last season when we had some weird metal staining on our vinyl liner and the plastic skimmers too. You must lower the chlorine levels before using but this product but cleaned it all away within a day! All plastic was white like new and it didn't harm the color on the liner just cleaned it up. Really amazing stuff. Follow with the metal out to keep it nice.

    I have a white fiberglass pool and have had trouble this year with brown staining due to metal in the water. Just sprinkle some of this in the water and wait an hour. The pool will be white white white! It seems a little pricey but is well worth it.

    This product works like magic within 24 hours, now you see it, now you don't! We've had our inground pool for about 15 yrs. The vinyl liner is only about 3 yrs old. I thought our pool was ruined from staining. Read about this product as well as others and decided to try this one. One bottle did a 20,000 gallon pool. Followed up with a bottle of metal free now the pool and steps look like new again!! VERY pleased with this product.

    used this productin a fiberglass pool. one container treated approx. 15 thousand gallons. i was discouraged because after a couple of hours most of the staining was still there. just be patient. 24 hours later my pool was white again. this stuff works great
