Certified Swimming Pool Stain Removers
What is acid washing?​ Acid washing is a common procedure and is sometimes necessary to remove staining.  The pool is emptied and a very strong mixture of muriatic acid is sprayed on the surface.  When the pool is refilled you may notice that the surface is a little more coarse (or etched). This occurs because the acid used to clean the pool will remove (dissolve) a small amount of the fine surface cement exposing the coarse aggregate beneath. Pool plaster is not designed for frequent acid washing.  Some within the pool industry believe that acid washing reduces the life of a pool surface by as much as 7 years.  As the experts in pool stain removal, we are able to correctly diagnose stains and provide the correct chemical treatment to remove the pool stain for you rather than draining and acid washing it. Our success rate in dissolving and treating stubborn stains and blemishes from most pool surfaces is impressive.

Common questions about acid washing ​1) How many times can a pool be acid washed?  Have you noticed that your pool feels slightly more course after an acid wash? No one knows how many times you can acid wash a pool before it becomes unsafe. What is known is that the muractic acid used works because it dissolves a fine layer of smooth concrete from the surface of your pool resulting in exposed aggregate which can be abrasive to swimmers hands and feet. 2) What are the risks? There is no doubt that acid washing can be effective in pool stain removal. However, you should only consider this procedure if absolutely necessary. When you drain your pool the surface becomes exposed to temperature variations that it was not designed to endure. After a day or so the risk increases of the pool surface separating (de- laminating) from the pool structure. The risk is higher if your pool is more than 10 years old. You can tell if this is occurring because the interior surface of your pool will sound “drummy” or hollow when tapped over the surface of the pool wall or floor. If you detect this drummy effect then your pool may be at risk of further long-lasting problems such as the formation of calcium nodules in the exact same spot or the premature deterioration of the pool surface. 3) Is acid washing expensive? Treatment costs are substantial and will vary from provider to provider so make sure you shop around. However, once you get a quote you will also need to also consider the additional costs and inconvenience of refilling your pool with water and rebalancing it back to swimming quality by the addition of products such as salt, buffer, pool acid and sunscreen (cynuric acid). 4) What happens if nothing else works? Our treatments have proven to be effective in over 95% of all the pools we have serviced. However, there are some marks and stains on the pool from silica build up and degradation that cannot be treated chemically.  In such cases the only option to remove the markings is to acid wash them. We also offer a full acid wash service to our customers in these circumstances. Unfortunately, in most cases, if acid washing does not rectify the issue then the pool surface may need to be replaced.
