How to Identify Pool Stains

Accurately identifying pool stains is the most challenging part of what we do.  Getting this right consistently has taken more than a decade of experience, a Bachelor of Science and plenty of costly chemical engineering.  Simply put, we’ve done all the expensive testing so you don’t have to!

Although different types of stains can be similar in color, the products needed to remove them can be very different.  For example, even very experienced pool guys will often completely misdiagnose stains and apply the wrong treatment to their clients’ pools.  This misdiagnosis results in unhappy pool owners, damaged surfaces, wasted money and no stain removal.   This is one reason why we have more than 450 pool guys and pool stores as regular clients.

Many pool stores often suggest various expensive ‘all-purpose’ stain removal products that have little or no effect on pool stains.  They suggest these products because they often have no idea what the stain is or how to remove it. In short, they are using your hard-earned money to experiment with different product options.  One of the most common questions we hear is how to properly identify pool stains.

Remember, if stain remover products are not matched to the right type of stain, it can make the staining worse! Adding the wrong product also makes stain removal harder as well.  More than 10% of the stains we treat are correcting a stain caused by poor advice from pool store operators.

Our customers often ask us to recommend the best stain remover for their pool.  The answer is not as simple as suggesting a single product as it depends on the type of stain.  Don’t worry, after a decade and 10,000 pools, we know how to identify pool stains, remove them, and keep them gone.
