Rust stains in pool interior

The best way to remove rust stains in swimming pools is by using our rust stain treatment kit.  Most rust stains in swimming pools come from metal objects that have fallen into the pool.  These include hairpins, nails, toys, or grinding or cutting of metal near the pool. When metal objects fall to the bottom of a pool, they begin to rust and stain the pool surface within a few days. We remove these types of rust stains every day without draining the pool.

Rust from metal fragments can also settle in a pool when building work, grinding or cutting of metals is happens near the pool. These fragments may not be noticeable at first but will begin to rust a few days later and appear as small rust spots. Remember, small rust spots are often introduced to the pool from cheap pool salt that contains small metal or mineral fragments.

What causes rust spots on pool walls

 
If you have a rust stain that is not from a metal object, it may be from the pool steel reinforcing.  These stains will get darker in colour and continue to get bigger over time. Although this type of rust stain is very uncommon, it differs from normal rust stains because it continues to grow and look worse over the life of the pool (see pictures below). In fact, these types of rust stains are first drilled, then plugged, and finally sealed to stop the steel from reacting (rusting) with the water. To repair this problem, epoxy products (designed for use in swimming pools) fill the holes. Then, the areas will have a new matching pool surface applied to reduce the visual impact of the repair.
Although our chemical treatments will improve the appearance of these types of stains, they may reappear after a few weeks if the steel is not isolated from the pool water. This is because the water will start rusting the steel again which will cause the stains to come back. Therefore, if you would like further information about how to repair these types of stains please contact a swimming pool repair company in your area.

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

REMEMBER LESS THAN 5% OF RUST STAINS ARE CAUSED BY RUSTING REINFORCING MESH. CALL US TO CHECK.

Rust contaminates in the pebble mix

Remember, less than 2% of rust stains are from small metal fragments or contaminated pebbles within the aggregate in concrete pools. The metal fragments often come from the metal rollers that crush the pebbles down to a particular uniform size.
 
On the other hand, individual contaminated pebbles can have mineral content that bleeds out over time. So, these stains may also leave a very small brown trail (only 1-2cm). Remember, these stains normally appear soon after the pool is newly built and may multiply in certain areas over time. These pebbles are sometimes referred to as ‘coffee rocks’ because of their colour.
 
In short, our treatment process accelerates the oxidization (rusting) process which will cause the rust stains to break down and dissolve permanently. Remember, this type of staining is normally evident in the first year.
