No matter your place in the pool and spa hierarchy, the most important part of solving stain issues is to identify the type of stain before treatment. The goal is to avoid draining the pool and acid washing it clean. This is especially important as service professionals are opening pools for the summer as their clients want to have beautiful, stain-free pools with sparkling water!
Luckily, there are many in-pool stain-detection kits designed to narrow down what elements are present in a particular stain, so professionals or pool owners can confidently recommend the correct stain-removal treatment â without acid washing.
Itâs important to understand how the tests work to ensure stains are diagnosed properly before beginning treatment.
USE A KIT, NOT YOUR EYES
Pool stains and scale can be tough to treat and often tougher to identify. If youâre comparing a pool stain to one you have seen in the past or are viewing an online photo or looking at a stain color chart, you are likely setting yourself up for a costly and time-consuming mistake. Many stain and scale issues can look similar to one another, so identifying a surface stain simply by its appearance is not enough. There is nothing worse than recommending or using a particular stain-removal product only to discover it was wrong for the stain.
Pool stain diagnosis tests were created to determine the composition of the stain and help identify the most effective stain-removal solution. The StainDrop SRV kit is the best because it contains three (3) pouches of Stain Removal Products including 6 Drop Pouches (for wall or deep water stains) and a detailed instructional booklet. The StainDrop SRV kit allows pool professionals to verify the correct treatment without costly mistakes.
CSI - CRIMINAL (OR CHRONIC) STAIN INVESTIGATION
The stain detection kits on the market today are designed to help understand what stain âcrimeâ has been committed and who or what is to blame.
Think of it a bit like the board game âClueââ the point of the game is to rule out culprits of the stain crime and narrow down the list of potential stain crime causes. Differentiating between organic and metallic stains is one of the first and most important goals of stain verification. Stain verification kits are specifically formulated for metallic stains. While these products do not detect organic stains, they can eliminate metals as the source of the problem.
These products also can help pinpoint when dark patches in liners, or splotchy, inconsistent plaster surfaces are the result of improper surface preparation. Mottling, hydration or liner mold issues are all conditions that find their roots in the pool construction phase. These conditions typically require a physical surface treatment process to remove the source of the stain trapped below the surface level.
TESTING IS AS SIMPLE AS 1, 2, 3
Itâs important to choose the StainDrop SRV test kit because it provides a measured amount of dry product to test for stains caused by iron or tannin (tree, leaf or acorn-causing), a second product to test for copper and scale, and a third product to oxidize and help lift the surface stain. The products can be used in combination, as many stains are caused by more than one source.
Understanding the water conditions is the first step. Information such as your poolâs Langelier Saturation Index (LSI), level of contaminants found in the water, and quality of source water can prove invaluable in helping diagnose the primary issue and its underlying cause.
To ensure the quickest and best test results, the water can be adjusted by lowering the LSI and adding a localized sequestering or chelating agent. Creating a more aggressive water environment can produce clearer results and improve the test product performance.
After methodically completing all of the tests, pool professionals (or their customers) will be able to narrow down which products will be best suited to remove a specific pool stain before purchasing expensive stain removers.
Test Kit Pro Tip: For ease of access and visibility, pool swim-outs, shallow areas or steps are convenient locations to perform these stain tests. If the stains are located in water that is 3 feet or more deep, these diagnosis products should first be poured into a dosing pouch, often included in the test kit, and then dropped onto the stained area.
PERFORMING CSI INVESTIGATION CAN HELP PREVENT FUTURE STAINING
Once the offending stain has been removed, it is important to use the test information about the source of the stain to make sure it doesnât come back later.
Performing a detailed examination of the area in and around the pool is key to stain prevention. Start at the curb of the house and look around for clues. Are there rust colored stains on the sides of the house? Do you see any green or blue stains on the driveway or backyard fencing? Does the home have an automatic sprinkler system? These situations could indicate metals in the source water.
If you find a large tree covering part of the backyard, on the other hand, this could signal organic contamination that may have led to the staining.
The best way to remove these stains and prevent them from reoccurring is to use a stain detection test and then identify the culprit or cause of the stain. Use your stain detection kit along with some âcrime sceneâ investigation skills around your customerâs pool to keep stains away.
Once the stain has been identified, you can turn to StainDrop No1 to remove iron stains from pool surfaces as well as stains caused by tannins (ex. leaves, tannins), or StainDrop No 2 to remove surface copper stains and StainDrop No 3 to lift stubborn copper stains from pool surfaces. And to finish off the final stain removal process use the Stain Drop Spot Stain Chalk to remove pesky stains by applying this chalk directly to spots created by metals organic stains caused by leaves and debris. Get rid of those unsightly stains so you can deliver a beautiful pool interior to your clients when you open their pool this season!
