We had some bad staining on our pool and I had trouble finding a company who wanted to help. I came across this company and it was a blessing! The product is amazing and literally worked overnight. Wade was super helpful and convinced us to give it a try and we are so glad we did. We were skeptical to say the least but it really works if you follow their instructions. Thank you Wade and company!!

I thought my pool was done for. Calcium took over. I search all over for a company that could help. I found one. If you have calcium buildup in your pool order this product it’s simple to use easy to follow instructions and fast delivery. You won’t be disappointed. My fibreglass pool looks new again.

I had copper stains in my pool for about 6 months. After spending hundreds of dollars on non-performing products purchased on bad advice of local pool stores, I found The Pool Stain Removers with an internet search. Their treatment sounded too good to be true. It turns out, it wasn’t too good to be true. It was awesome! I find myself going outside several times a day just to gaze at my like-new pool. I am so pleased. Thank you Wade!.

After multiple attempts to remove brown/green stains on sides of in ground pebble pool, I was resigned to the fact a new pool surface was necessary. The Pool Stain Removers came through with a self applied chemical treatment that removed stains within 5 days! Process requires a little attention for a few days and is not labor intensive. For those of you dealing with pool stains, please contact Wade and he will solve your issues. This is my first recommendation ever on Facebook. Please give then a try.

I wish I had some before and after photos to share, but I don't. This product worked fantastic! We have an inground pool and had used copper based algaecide which combined with shock left mottled blue stains and some darker stains all over the plaster surface. It looked terrible. We tried everything and I had resigned myself to the possibility of draining the pool and acid washing. Then my wife found this online and we decided to give it a shot. After about two weeks, the surface looked as good as new. In addition to the product being very effective, the support I received was first rate as well. Hopefully I won't mess the pool up again, but if I do, I know where to go for help!

After owning our property for 20 years i was skeptical as to whether these products would work. I cant believe the difference and my pool has never looked so good. Would highly recommend The Pool Stain Removers

Our pool sides and bottom were stained due to either garden run-off or rotting vegetation after a particularly stormy and wet winter. Not badly but it was plainly obvious. The stain could be removed by vigorous rubbing with a nylon scourer but that obviously wasn't and option for the whole pool. Pool Stain Removers treatment was easy to apply and worked perfectly. Even though the staining wasn't bad, now that it's gone our pool looks pristine, brighter and bluer.

I rarely review at 5 stars but this product does exactly what it says on the tin. Use it properly and it works wonders. We are ordering again to retreat our heavily used family Pebblecrete pool… nearly 6 years later.

I can't say enough about this company, product and owner, Wade. After being so discouraged about the unsightly scaling in my pool, I was fortunate to take a chance on Pool Stain Removers. Wade walked me through the whole process and answered numerous questions...he was so kind, patient and knowledgeable. My pool now looks 100% better and I never had to do an acid wash or hot start...just this amazing product! I am so very grateful and highly recommended!

Fixing your stain is easy

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.

  • Check the pH and chlorine levels
  • Pour in the stain prevention polymer
  • Sprinkle the powder around the pool
  • Brush the pool (no scrubbing needed)

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.

Best of all, we’re only a phone call away if you have any questions. If you would still prefer a technician, no worries, we can help you.

Citric acid stain remover that is too weak to remove pool stains

Why don't retail stain products fix stains?

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:

  • Weak Concentration: Citric acid is gentle enough to eat which also means it’s won’t dissolve the molecular bonds on a stained full of water!
  • Inadequate Volume: Small 1kg bottles of weak powder are incapable of treating a huge body of water.
  • Incorrect Diagnosis: “All-purpose” products aren’t chemically tuned for your specific stain type. Failed treatment attempts fuse the stain to the surface making it even harder to remove.
  • No Prevention: Without a sequestering agent, dissolved minerals simply settle back onto your pool floor within days, bringing the stains right back.

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.

The Pool Stain Removers Guarantee Seal

Our Results Guarantee

If our treatment doesn’t remove your stain, but another product does — including an acid wash — we’ll refund all your money.

Australia's Experts in Pool Stain Removal

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.

Frequently Asked Questions

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.  

  1. Most pool shops must sign exclusive product supply agreements with their suppliers to get bigger discounts.  This means that they often agree to only sell the products that come from their distributor/franchise.  Ever noticed that all the products at the pool shop carry the same brand on the label?
  2. If we did sell through pool shops, then the product cost would double because the pool shop (and the distributors/wholesalers) all add their profit margins onto the price you pay.
  3. There is great money to be made for pool shops that suggest acid washing because they make good profit on the acid wash, and they also get to sell you all the start-up chemicals you need when the pool is filled back up.  Why would they suggest our kit and lose that money?
  4. Some pool stores lack have the expertise to properly diagnose stains so they will likely sell you the wrong product.

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.

Man acid washing swimming pool

Don't drain or acid wash to fix pool stains

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

  • High Cost: The huge excess water bill, the acid wash cost, and the chemicals to re-start the pool, all add up.
  • Surface Damage: Acid etches the finish, creating a rough, ‘sandpaper’ feel that grazes skin.
  • Short-Lived Results: Stains often return within weeks because the surface is rough and etched.
  • No Guarantee: Acid washing does not come with a guarantee of removal.

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.
