Common Mistakes in Pool Acid Washing and How to Avoid Them

Acid washing is a powerful method for removing stains, algae, and calcium buildup, but improper techniques can cause serious damage to your pool’s surface. Many Scottsdale homeowners attempt DIY acid washing without understanding the risks, leading to costly repairs. Here are the most common mistakes in pool acid washing in Scottsdale, AZ, and how to avoid them.

1. Using Too Much Acid

Some pool owners believe that a stronger acid solution will clean more effectively, but too much acid can severely damage plaster and pebble finishes. Overuse can create rough patches, weaken the pool surface, and accelerate the need for resurfacing.

How to Avoid It: Always dilute muriatic acid properly—typically a 1:3 or 1:4 acid-to-water ratio—ensuring an effective clean without harming your pool’s surface.

2. Not Preparing the Pool Correctly

Failing to fully drain and clean the pool before applying acid can lead to uneven results. Leaves, dirt, and debris can interfere with the acid’s effectiveness, leaving some areas discolored.

How to Avoid It: Before acid washing, drain the pool completely, remove all debris, and rinse the walls to ensure the acid solution works evenly across the entire surface.

3. Skipping Safety Precautions

Muriatic acid is a hazardous chemical that can cause burns, respiratory issues, and serious eye irritation if not handled properly. Many DIY homeowners fail to wear protective gear, exposing themselves to unnecessary risks.

How to Avoid It: Always wear gloves, goggles, long sleeves, and a respirator mask. Work in a well-ventilated area and avoid direct exposure to fumes by standing upwind.

4. Leaving Acid on the Surface Too Long

In Scottsdale’s dry heat, acid can dry quickly, leading to over-etching of the plaster. This can result in permanent surface damage, making the pool rough and more susceptible to algae growth.

How to Avoid It: Apply acid in small sections and scrub immediately with a pool brush. Rinse each area thoroughly before moving on to the next section to prevent prolonged exposure.

5. Failing to Neutralize and Dispose of Acid Properly

Acid that isn’t neutralized before being drained can cause damage to Scottsdale’s desert environment and pool plumbing systems. Many pool owners don’t realize they need to neutralize the acid before rinsing it away.

How to Avoid It: Use soda ash or baking soda to neutralize the acid before draining the pool water. If unsure, hiring a Scottsdale pool service ensures proper handling and disposal.

6. Acid Washing Too Frequently

Acid washing removes a thin layer of plaster each time, so performing it too often can lead to premature deterioration. Some Scottsdale homeowners mistakenly acid wash every year, significantly reducing their pool’s lifespan.

How to Avoid It: Limit acid washing to every 5-7 years unless there is severe staining or calcium buildup. Routine brushing and proper water chemistry can help reduce the need for frequent acid washes.

7. Attempting DIY Acid Washing Without Experience

While DIY acid washing may seem like a cost-saving option, improper techniques can cause irreversible damage. Without proper knowledge, you risk etching your pool, harming yourself, or failing to remove stains effectively.

How to Avoid It: Hiring a Scottsdale pool equipment repair expert ensures the job is done safely, effectively, and without risking damage to your pool.
