How do I get rid of a stain?
PristineBlue® is designed to minimize staining problems. Some of the most common causes of staining are out of balance water, chemical overdosing and failure to follow the procedures in the Pool & Spa Care Guide. Due to the bleaching action of chlorine, stains that were not previously visible may appear on the pool surface after chlorine use is discontinued.
The most important element of treating stains is determining whether it is a metal/mineral or organic stain. If there is any doubt, treat as a mineral stain first. The treatment (chlorine shock) used for organic stains can sometimes set a mineral stain and make it more difficult to remove. Most stains can be removed instantly while older stains may take several days or more than one stain treatment. To determine whether the stain you’re dealing with is mineral or organic in nature, perform a “Sock Test”:
Place a small amount (1/2 cup to 1 cup) of PristinepHDown™ in an old sock and tie to form a small pouch. Place the sock on the stain for 3 or 4 minutes, using an extension pole to hold the sock in place if necessary. Remove and discard. If the stain has lightened or changed color where the sock was placed, the stain is mineral in nature and should be treated according to the suggestions below for mineral stain removal.
If there is no change to the stain with the above test, make a similar pouch with a second old sock and PristineExtra®. Set this sock on the stain for 3 or 4 minutes, using an extension pole to hold the sock in place if necessary. Remove and discard. If the stain lightens or changes color, the stain is organic and should be treated according to the suggestions below for organic stain removal.
Mineral Stain Removal Method:
Isolate the heater from the system when dropping the pH below 7.0. Lower the pH to 6.8 and the alkalinity less than 90. Add 3 ounces of PristineClean® per 1,000 gallons of water. Run the filter until the stain is removed. A second application may be necessary after 72 hours. Increase the pH after the stain has lifted.
ALTERNATE METHOD: Adjust the pH between 7.2 and 7.6. Add oxalic acid according to label directions. Run the filter continuously during this process. Rebalance the water.
Organic Stain Removal Method:
Lower the pH to 7.2. Shock with PristineExtra® (2 pounds per 10,000 gallons of water). Run the filter continuously and backwash daily. Repeat if necessary.
