How to Remove Swimming Pool Stains

Written by:  Danny Rhodehamel

A stained swimming pool is an eyesore that disrupts the sparkling blue water every pool owner dreams of. Fortunately many stains are identifiable and treatable using Jacks Magic products.

Tips & Warnings

Step by Step

Step 1

The first important step is to balance your pool water within stain identification and removal parameters. Although your water balance may be “perfect” for normal daily operating conditions, it could need some adjustment for successful pool stain identification and removal. Balance your water within the parameters listed below before proceeding to the Jack’s Magic Stain Identification Kit or Jack's Magic Stain Removal Treatments.

Step 2

Here is a list of pool water components and the balance parameters for pool stain identification and treatment: Free and Total Available Chlorine 1 - 3 parts per million (ppm); pH 7.0 - 7.4; Total Alkalinity 80 ppm or lower; Calcium Hardness 200 - 400 ppm; Cyanuric Acid (Stabilizer) (CYA) below 70 ppm; Total Dissolved Solids (TDS) Below 1200 ppm (except salt systems)

Step 3

If using a bromine sanitizer system: 2-6 ppm (of bromine) If using a biguanide sanitizer system: 30-50 ppm, (of biguanide)

Step 4

If CYA level is higher than recommended balance parameters, dilute level by draining water from the pool and adding fresh water. Be sure to check reading again; failure to do so may result in ineffective pool stain identification or removal. PLEASE NOTE: CYA is not applicable in bromine or biguanide pools.

Step 5

If TDS level is higher than recommended balance parameters, dilute level by draining water from the pool and adding fresh water. Be sure to check reading again; failure to do so may result in ineffective pool stain identification or removal.

Step 6

After balancing your pool water within the parameters above, use a Jack’s Magic Stain Identification Kit (according to directions) to specifically determine which of the following treatments in Steps 8- 11 will best remove your swimming pool stain. A Jack’s Magic Stain Identification Kit takes the guesswork out of swimming pool stain removal.

Step 7

FOR BEST RESULTS: Use several ounces of Jacks's Magic Blue Stuff, or some muriatic acid, in the area that you will be performing the test.

Step 8

Follow directions for the stain removal treatment identified as the best for your swimming pool stain. Here are some stain removal tips to remember: If you get no apparent reaction when doing any of the (4) Jack’s Magic Stain Identification Kit treatments, try using the Jacks's Magic Blue Stuff for six weeks and then trying the treatments again.

Step 9

To prevent any future pool stains, use Jacks's Magic Blue Stuff as a weekly preventative maintenance product. Maintain levels 10-12 ppm. A Jack’s Magic sequest test kit can verify that these levels have been achieved.

Step 10

To maintain proper water balance, use an accurate and reliable test kit. Jack’s Magic has found the single tablet method to be extremely accurate and stable method for testing pool and spa water. Tablets in the Jack’s Magic Professional Test Kit are specially formulated and buffered for the warmer temperatures associated with swimming pools and spas.

Step 11

If you have difficulty getting a free chlorine reading after doing a STAIN SOLUTION #2 Treatment, test the Total Available Chlorine. Assume this reading is the true Free Available Chlorine reading. STAIN SOLUTION #2 often causes an error in the DPD #1 test; this reaction may last up to a month while STAIN SOLUTION #2 is still in the water.

Donna - Have you done a stain id test? If you don't want to buy the kit, try placing a vitamin C tablet on the stain to see if it lightens it. If it does, you can use a simple stain remover to get rid of the stain. If you’re pass this point, give us a call at 877-372-6038 and ask for Alex at x714.

We have been trying to remove a stain all summer - we have been told it was a metal stain becuase our PH was so low it pulled copper from the heater - once we raised the ph the stain appreared - we have spent tons of money on removers and metal traps and only once did the stain come out but after rains it came back again - we were advised to get the copper out of the pool by draining and refilling - so we did - now the copper is at less than 1 and the stain will not come out - Someone came to look at it today and is telling me now that they think it is from behind the liner and they is a draining issue in the yard- Not sure I believe that after all the stain did not appear until we got the ph up .HELP

Margaret - If you have hard water, your brown stain may be due to rust from metals and minerals. Our vendor recommends using "Super Rust and Scale Removal". With hard water, you will have to use this product periodically to keep the stains from coming back.

JOHNNY MARTINEZ - Do not use steel wool or sandpaper, or mineral acids, bleaches or chlorine cleansers. There are several levels of "staining". For minor discolorations use a commercial metal polish. For light rust, use a stronger cleaning agent like Simichrome Polish. For heavy rusting, use navel jelly with a Scotchbrite pad. Work in the direction of the existing grain.

JOHNNY MARTINEZ - The presence of chloramines is thought to be the most important environmental factor in the corrosion of stainless steel. Chloramines are the byproducts formed by the reaction of chlorine and contaminants from bathers. They are the cause of most eye and nose irritation for pool users. These chloramines are controlled by periodically shocking your pool whenever you see your combined chlorine levels exceed limits.


how do you remove stains from a stainless steel finish !!!!
