Rust Stains in Pool
Rust stains in your pool?
Our rust stain remover removes stubborn rust stains in less than two weeks without draining the pool or acid washing the surface.
Most rust stains are caused by:
Metal objects: Staples, nails, kids toys and batteries will leave rust staining the surface. These rust stain types will usually leave a stain in the exact shape of the object.
Nearby cutting or grinding of metal: Cutting metal near the pool can blow tiny metal fragments that can later rust. These will appear as small spots, scattered throughout the pool. They often take several days to appear after the cutting has been done.
Low-quality pool salt: Small mineral fragments from contaminated pool salt can leave tiny rust spots in pool surfaces. If there has been no metalwork near your pool recently, then salt contamination may be the cause of tiny rust spots.
Our treatment removes almost every type of rust stains in pool surfaces without the hassle of draining your pool.

How we fix rust stains in pools
Our granular treatment safely dissolves rust stains across all pool types without any harsh bleaches or chlorine. Powered by our 7 active ingredients, our treatment helps break down and dissolve rust staining so it can be lifted from the pool surface.
Don't acid wash your pool to fix rust stains
Acid washing is often used to improve rust stained pool surfaces, but it isn’t necessary.
Acid washing requires the pool to be drained and exposes the surface to very strong acids which is why it dissolves a layer of the surface material.

Uncommon Pool Rust Types
While less common, rust stains don’t always come from a fallen metal object. As shown below, rust can bleed through from reinforcing steel (rebar) underneath or iron-rich minerals in the pebble finish. If you need help identifying the source of your stain, feel free to contact us.
Is your rust stain coming from reinforcing steel?
Some stains can originate from the pool’s steel reinforcement. Rust stains from reinforcing often takes years to show up – often on walls. These require the pool to be drained and a physical repair, rather than simply treating the stain. We do not do these repairs.
Here’s how you can tell if you have rust from steel reinforcing:
- Stain leaves a brown trail
- Stain slowly gets bigger & darker
- Rust stain on the vertical walls
- Stain improves after cleaning - then returns
- More appear in random places over time
In our experience, less than 5% of pool rust stains are actually caused by rusting reinforcing steel. If you want us to take a look at your stain before you buy, give us a call!
Contaminated Pool Pebbles
Some rust stains come from tiny metal fragments embedded in the pebbles used in concrete pools. These fragments typically come from the metal rollers used to crush the pebbles down to a uniform size during manufacturing.
In other cases, individual pebbles carry mineral contamination that leaches out over time. These pebbles leave small brown trails – usually only 2-5 mm – scattered across a few random areas of the pool surface. This type of staining tends to appear early in a pool’s life, often within the first year, and may multiply as more contaminated pebbles are exposed. Because of their distinctive colour, these pebbles are commonly known as “coffee rocks.”
Our treatment process accelerates the natural oxidation (rusting) process, causing the minerals to break down and dissolve away much faster than they would on their own.
Frequently Asked Questions
Here are some of the most common questions we hear about rust stains. Please feel free to call us if you would like further information.
Can rust stains be removed without draining the pool?
Many surface rust stains can be treated while the pool remains full. If the rust is from reinforcing steel then it will require draining and a physical repair.
Will a liquid "metal remover" from the pool shop fix rust stains?
No, they don’t remove rust stains. Liquid metal sequestrants only hold metal ions in suspension in the water—they cannot lift existing stains off the surface. To fix rust staining, you need to dissolve the stain off the pool walls/floor with our rust stain treatment.
Is it safe to use on fibreglass / vinyl pools?
Yes. The treatment is suitable for fibreglass pools when applied correctly. The kit has no bleaches or chlorines so the surface colour is protected.
I live outside your service areas. What do I do?
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.
