Over 90% of our clients use the Pool Stain Remover DIY treatment kit. This is because it’s very easy to do and saves you money.
The kit includes detailed instructions, along with a step-by-step video guide to walk you through the process. It only takes a few minutes to complete. It’s the treatment that removes the stains and calcium, not a technician. So you’ll get the same results that we do.

Think about it: Most pool shop stain removers are made from citric acid which is a common ingredient you’d find in many common soft drinks like Sunkist and Sprite. Citric acid is gentle, but that’s the problem. A small bottle can’t bind enough metal to make a dent in 40,000 litres of water!
In fact, in 2025, 8 out of every 10 new clients we helped had already bought and tried an “all-purpose stain remover” before they found us.
Generic retail products typically fail for four reasons:
Don’t waste your time and money on weak retail products that are never going to work. Choose a professional-grade solution that works the first time from Australia’s favourite swimming pool stain remover.
If our treatment doesn’t remove your stain, but another product does — including an acid wash — we’ll refund all your money.
Every day, pool owners waste time and money on ‘all-purpose’ retail treatments that don’t work. Most stain products contain a single, mild organic acid which is not strong enough to remove a pool stain.
How is our treatment better? We blend seven active ingredients, including ion exchangers, sequestrants, dispersants and polymers that all work together to remove 14 types of pool stains. Then, our liquid stain prevention polymer (SSE) helps stop the stains from coming back.
Experience professional-grade results with no water draining and no damaging acid washes.
Here are some of the most common questions we receive about our products. Please feel free to call us if you would like further information.
No. All of our treatments work with the water still in the pool. There is no draining, even after all the stains have gone. The kit also includes our stain prevention polymer (SSE) to help stop stains from coming back.
There are 4 reasons why we don’t sell our products in pool shops.
You can safely swim again after 7 days. Even though our products are safe for swimmers, during the first 7 days the pH is low and it is working hard to break down the stains. It is best to stay out of the water during this time as the low pH may be uncomfortable for some swimmers.
At our Strathfield, NSW manufacturing facility, we blend seven active ingredients to create our powerful stain remover. Most pool shop stain removers rely on a single, weak organic acids like citric acid, to remove stains. Our unique, broad spectrum blend is significantly stronger and works on up to 14 different types of stains. We tackle a broader range of stains, which is why almost all of our clients see great results. In 2025, 8 out of 10 clients had already tried another stain remover before using our product.
The products work on almost every pool surface type (except small inflatable kids’ pools). It is effective on Pebblecrete Pools, Glass Pebble pools, Quartzon, Beadcrete, Marblesheen, Vinyl Liners, Fibreglass Pools, Epoxy Pools, Tiled Pools, Ecofinish, Painted Pools, and Natural Stone Surfaces. We have treated 20,000 pools since 2013.
We recommend keeping pets out of the pool for the first seven days. That said, more than 200 clients have told us their pets drank or swam in the treated water right away — with no health issues.
We can still help you because we send our kits all over Australia. More than 90% of our clients use the DIY kit because it is so simple. It comes with easy-to-follow instructions and a short video showing you exactly what to do.
Acid washing is a permanent mistake, costing $1,100 – $2,300 once you pay to refill the pool and add new chemicals. It is a lot of money that doesn’t keep stains away.
Acid washing aggressively strips away your pool’s surface, leaving it rough, blotchy, and abrasive. We regularly hear from parents whose kids have stopped swimming altogether because the acid washed surface is now too rough on their hands and feet.
The Hidden Truth About Acid Washing
Don’t damage your pool with acid washing. Our treatment is not only much cheaper, but also protects your pool’s surface. A clean pool should be beautiful and comfortable—not a hazard for your kids’ hands and feet.
