Over 90% of rust stains in swimming pools are caused from metal objects that have fallen into the pool such as hair pins, nails, toys or other metal items. When these items are immersed in salt water, they begin to rust and stain the pool surface within a few days. We remove these types of stains every day.
Rust fragments can also settle in a pool when building work, grinding or cutting of metals is done near the pool. These fragments will not be noticeable at first but will begin to rust a few days later and appear like small rust spots. Small rust spots can also be introduced to the pool from cheap pool salt containing small metal fragments.
The good news is that our treatments can remove rust stains completely within a few days without draining the pool or acid washing. Our process is very effective in treating and removing rust stains from concrete, vinyl lined and fibreglass pools. Our products sometimes completely remove mild rust spots in less than one hour!

Signs of pool rust staining:
- Brown stain that won’t brush away
- Retail stain products won’t remove it
- Forms the shape of object (eg. nail, bottle top)
- Stain not changing colour or getting bigger

Rust from reinforcing mesh
If your rust stain is large (8-40mm across) and dark in colour and continues to get bigger, it may be coming from the reinforcing mesh used in the pool’s structural shell. Although this type of rust stain is very uncommon, it differs from normal rust stains because it continues to look worse over the life of the pool (see pictures below). This type of rust stain needs to be physically drilled out, plugged and sealed in order to stop the steel from reacting (rusting) with the water. To repair this problem coloured epoxy products which are designed for use in swimming pools are used to plug the hole.
Although our chemical treatments will improve the appearance of these types of stains, they may reappear after a few weeks or months if nothing is done to permanently isolate the rusting steel from the pool water.
If you would like further information about how these types of stains can be repaired please call us.
Reinforcing steel is causing the stain if…
- Stain leaves a brown trail
- Stain is slowly getting bigger & darker
- Dark stain on the vertical walls
- Stain returns after removal/cleaning
NOTE: LESS THAN 5% OF RUST STAINS ARE CAUSED BY RUSTING REINFORCING MESH. CALL US TO CHECK.
Rust contaminates in the pebble mix
Less than 2% of rust stains are caused from small metal fragments, or contaminated pebbles within the aggregate in concrete pools. The metal fragments often come from the metal rollers that are used to crush the pebbles down to a particular uniform size.
Individual contaminated pebbles can have heavy mineral content and this mineral bleeds out over time. These stains may also leave a very small brown trail (only 1-2cm). These stains normally appear soon after the pool is newly built and may multiply in certain areas over time. Our treatment process rapidly accelerates the oxidization (rusting) process which will cause the rust stains to break down and dissolve permanently.
Removing metals from pool water
Customers with large rust stains should consider using CuLator Metal Eliminator in addition to our treatment. This product will help remove the excess metals from the water to help prevent the stain from reappearing later. Our standard treatment will dissolve metal stains but will not physically remove all of them from the water. Common liquid metal treatments only ‘suspend’ rather than actually remove the metal from the water. CuLator Metal Eliminator is unique because it can physically remove metals from pool water. Your pool shop will assist you in measuring the metal levels in your pool water.
