What is Acid Washing?

Acid washing is the process of removing a thin layer of the plaster from a swimming pool to get rid of stains, dirt, algae, and other unwanted materials that can’t be removed with regular cleaning. It’s a process that can only be done on plaster and concrete pools, not on vinyl or fiberglass pools. The process involves draining the pool, applying an acid solution to the pool’s surface, and scrubbing it off after a certain amount of time.

Although acid washing can be done by homeowners, it’s usually recommended to hire a professional pool service company as it involves handling harsh chemicals and specialized equipment. Acid washing is a quick and effective solution for removing tough stains and debris that are otherwise hard to remove, making your pool look fresh and new again.

It’s important to note that acid washing should not be done too frequently, as it can weaken the plaster, making it more prone to damage and deterioration. Typically, acid washing should be done once every three to five years, depending on the condition of your pool.

Overall, acid washing is a popular and effective method for cleaning and revitalizing a plaster pool, and it can help bring back the shine and beauty of your pool.

Understanding the Process of Acid Washing Your Plaster Pool

1. Draining the pool: Before starting the process of acid washing, you need to drain your pool to a proper level. Draining the pool to an appropriate level will ensure that the washing solution doesn’t overflow.

2. Mixing the solution: The next step is to mix the washing solution. The solution should be a mixture of muriatic acid and water. The proportion of the solution depends on the severity of the stains on your pool’s plaster. It is important to follow the instructions on the packaging and wear proper protective gear when mixing.

3. Applying the solution: The solution should be applied to the pool’s plaster using a sprayer or a watering can. It is important to apply the solution evenly and thoroughly on the surface of the pool’s plaster. You should also avoid applying the solution on metal and other non-plaster surfaces to prevent corrosion.

Once the solution is applied, you need to leave it on for a specific period of time, which depends on the severity of the stains on your pool’s plaster. After that, the solution needs to be neutralized and washed off with water. By following these steps, you can ensure that your pool’s plaster is properly acid washed.

When to Acid Wash a Plaster Pool?

Knowing when to acid wash your plaster pool is crucial to maintain its appearance and longevity. If you notice stains, discoloration, or scaling on your pool surface, it might be time to consider acid washing. These issues not only affect the aesthetic appeal of your pool but can also damage the surface, making it rough to the touch.

The frequency of acid washing depends on several factors such as usage, water chemistry, and weather conditions. On average, you should acid wash your pool every 3-5 years, but if your pool experiences heavy use, you may need to acid wash it more frequently. Additionally, if your pool has algae or other persistent stains, it may require an acid wash before the recommended timeframe.

It is also essential to pay attention to the signs of damage to the pool surface. If you notice cracks, chips, or peeling on the plaster, you should address these issues before scheduling an acid wash. If you don’t, the acid wash can worsen the damage and lead to further costly repairs.

Ultimately, the best way to determine if your pool needs an acid wash is to consult with a professional pool service technician. They can assess your pool’s condition and recommend the appropriate course of action to restore your pool’s beauty and extend its lifespan.
