Swimming pool vinyl liner stained

Cause

Pool chemicals, metals, leaves and organic debris

Repair

  • staining of pool surfaces is relatively common. Not all stains require treatment – the issue is whether or not the appearance of the stain is beyond what you are prepared to accept

  • best results are likely to be achieved by tackling the stain quickly – they can be more difficult to remove, or even impossible to remove, if left for a long period

  • best results also come from identifying the cause of the stain and addressing that specifically

  • contact the manufacturer or supplier of the vinyl liner for their recommendations and advice. Manufacturers often recommend (and even supply) specific proprietary cleaning products

  • check the fine print of proprietary cleaning chemicals for potential interactions. In some cases a product may be less effective if there are high levels of chlorine present, for example

  • be aware that some liners have a bleachable surface. Always carry out a test on a small area of the stain first

  • if you think the pool chemicals are the cause of the problem, ask the pool supplier for alternative options

  • with organic staining, one approach is to ‘shock’ the water with a very high level of chlorination. Brush the stains thoroughly, letting the pool filter system run for several hours

  • if initial attempts at removing the stain don’t work, call in professional help, or take very good photographs of the stain to the pool supplier for their guidance

  • the best option is always to prevent staining in the first place. Maintain the correct chemical balance in the water and keep the pool free or organic matter through skimming and vacuuming
