Keeping your swimming pool in top condition often requires a pool cleaning acid wash to remove stubborn stains, algae, and calcium deposits. This process helps restore the pool’s surface, making it look new and improving water quality.

Key Takeaways

• Acid washing removes stains, algae, and calcium deposits.
• The process should be done every 3-5 years to avoid surface damage.
• Liquid chlorine helps clean the pool before the acid wash.
• Hydrochloric acid is essential for deep cleaning.
• Chlorine tablets help maintain cleanliness after an acid wash.
• You can buy hydrochloric acid from pool supply stores in Australia.
• Always wear protective gear when handling acid.
• Rinse and neutralise the acid properly after washing.
• Regular maintenance extends the lifespan of your pool.
• Hiring a professional ensures a safe and effective acid wash.

What is Pool Cleaning Acid Wash?

Pool cleaning acid wash is a deep-cleaning process that removes tough stains, algae, calcium buildup, and mineral deposits from a pool’s surface using a diluted acid solution. It involves draining the pool, applying hydrochloric acid, scrubbing the surface, and thoroughly rinsing and neutralising the acid. This method restores the pool’s appearance and improves water quality, typically recommended every 3-5 years for concrete or plaster pools.

Why is acid washing necessary?

Over time, pool surfaces collect grime, mineral buildup, and algae, making regular cleaning insufficient. Acid washing is an effective method to deeply clean and rejuvenate the pool, ensuring a safer and more enjoyable swimming experience.

Signs Your Pool Needs an Acid Wash

• Stubborn stains that do not come off with regular scrubbing
• Discoloured or cloudy pool water
• Rough pool surfaces due to mineral and calcium deposits
• Frequent algae growth despite chemical treatments
• A general dull or aged appearance of the pool walls and floor

Preparing for an Acid Wash

Before starting an acid wash, ensure you have all the necessary chemicals and safety gear. A common cleaning solution involves liquid chlorine 20 litres, which helps eliminate bacteria and organic debris before the acid wash process begins. This step ensures that contaminants are minimised before applying the acid solution.

Choosing the Right Acid for the Job

One of the key components in an acid wash is hydrochloric acid for pool cleaning. This chemical effectively removes scale, stains, and algae growth, restoring the pool’s original look. However, handling it requires care and the right protective equipment. Following the manufacturer’s guidelines when using hydrochloric acid is essential to avoid accidents or damage to your pool.

Essential Pool Chemicals to Maintain Cleanliness

Maintaining proper chemical balance is important to keep your pool clean after an acid wash. Many pool owners use chlorine tablets to maintain sanitised water and prevent algae from returning. Regularly using these tablets helps ensure that bacteria and contaminants do not thrive in your pool, keeping the water clear and safe for swimming.

Where to Buy Acid for Pool Cleaning?

To perform an acid wash yourself, you must source the right chemicals. You can buy hydrochloric acid in Australia from local pool supply stores like Viva Blu, hardware shops, or online retailers specialising in pool maintenance products. Choosing high-quality products and storing them properly is important to prevent leaks or contamination.

Step-by-Step Guide to Acid Washing a Pool

1. Drain the Pool Completely

Ensure all water is removed before starting the acid wash. A submersible pump can speed up the process. Leaving water in the pool can dilute the acid, reducing its effectiveness.

2. Prepare the Acid Solution

Mix hydrochloric acid with water in a 1:1 ratio. Always add acid to water, never the other way around, to prevent dangerous reactions. Using a large plastic container is recommended to ensure safety.

3. Apply the Acid Wash

Using a sprayer or watering can, evenly distribute the acid solution across the pool surface, starting from the deep end. Work methodically to ensure even coverage and avoid overexposure to fumes.

4. Scrub the Pool Surface

Use a pool brush to scrub areas with stubborn stains. Work in sections to ensure even cleaning. This step is crucial to breaking down calcium deposits and algae buildup.

5. Rinse Thoroughly

Once the acid wash is complete, thoroughly rinse the pool with clean water to remove any remaining acid. Any leftover acid residue can damage the pool surface over time.

6. Neutralise the Acid

Sprinkle baking soda over the pool surface to neutralise any remaining acid before refilling the pool with fresh water. This prevents residual acidity from affecting the new water balance.

7. Refill the Pool and Balance Chemicals

After refilling the pool, test the water and adjust the pH and chlorine levels as needed. This helps restore a safe and balanced swimming environment.

• Always wear protective gear, including gloves, goggles, and a mask.
• Work in a well-ventilated area to avoid inhaling fumes.
• Keep acid away from children and pets.
• Have a neutralising agent, such as baking soda, on hand.
• Never mix hydrochloric acid with other chemicals, as dangerous reactions may occur.

While some pool owners prefer DIY acid washing, hiring a professional ensures safety and a thorough cleaning. Experts have the proper equipment and experience to handle chemicals safely, reducing the risk of improper application or surface damage.

Environmental Considerations

• Dispose of acid wash water responsibly to prevent harm to plants and waterways.
• Use eco-friendly alternatives when possible to reduce chemical impact.
• Ensure that acid wash runoff does not enter stormwater drains, as this can cause environmental damage.
