Acid Wash Pool Cost

The cost to acid wash a pool depends on your geographical location, the pool's accessibility, the time of year and the size of the pool. For a pool measuring approximately 500 square feet, the costs usually range from a low of $178 to a high of $255. This price includes the cost of the labor and all of the necessary chemicals.

If you intend to clean your own pool, then your only expenses are the various chemicals, which cost around $30. You may also need to buy a sump pump and rent or purchase protective clothing.

When To Acid Wash A Pool

When To Acid Wash A Pool

Building a pool is a wonderful way to get more enjoyment out of your backyard, but pools require regular maintenance to keep the water clean and to prevent the buildup of algae and stains. If you leave your pool untended for any length of time, the growth of algae starts to stain the pool's surface and makes the water slimy. When your water is stagnant and you cannot see the bottom of the pool, it's time to drain the pool for an acid wash. You may also decide to acid wash a pool if calcium deposits have caused discoloration.

Acid Washing Vs. Pool Cleaning

Normal pool cleaning doesn't involve draining the water. Common pool cleaning procedures include:

  • Scrubbing the sides and bottom of the pool with a stiff brush
  • Removing leaves and floating debris with a net
  • Cleaning or replacing the cartridges in the pool filter
  • Testing the water's chemical levels and adjusting as necessary

Acid washing a pool is a more serious endeavor. It involves draining the pool completely and then using an acid solution to remove a very thin layer of the pool's surface, thereby removing any calcium deposits and stains.

Acid Washing & Pool Types

An acid wash is only suitable for pools with plaster or Pebble Tec surfaces. Furthermore, pools with old, thin plaster may not be suitable, in which case the only option is to resurface the pool completely. A professional can determine if acid washing is the best route.

Bear in mind that the acid wash removes a thin layer of the pool's surface, so you shouldn't do it too often. When you acid wash the pool every year, it increases the frequency of resurfacing. Try to avoid acid washes when possible by regularly maintaining your pool to reduce the buildup of calcium and algae.

DIY Or Hire A Pro?

You may decide to cut your pool maintenance costs by doing the acid wash yourself, but chlorine and acid are hazardous chemicals, and there is a risk of injury if you don't use protective clothing. Additionally, incorrect application of the acid could damage your pool, removing too much of the surface or leaving unsightly streaks. You may also find that, if you have to hire a sump pump pro, source the correct chemicals and buy protective gear, then you don't actually save much money. For most people, hiring a professional pool cleaner is a quicker, safer and more effective way to restore the look of a pool.

How To Acid Wash A Pool

While it's possible to acid wash a pool yourself, working with the necessary chemicals is dangerous. Unless you are confident in your abilities and have all of the necessary safety gear, it is usually a better idea to hire a professional pool cleaner. If you decide to proceed with the project, follow these steps:

  1. Drain the pool, clearing debris as you go. You may need to rent or purchase a sump pump for this.
  2. Using a stiff brush, scrub the interior of the pool with chlorine to remove algae.
  3. Make up a solution of three parts water to one part acid in a watering can. Always add the water to the can first.
  4. Put some soda ash in the bottom of the pool to neutralize the acid as it pools there.
  5. Wet a section of the pool surface with a hose. Leave the hose running, as you need it to quickly rinse off the acid later.
  6. Pour your diluted acid onto the wet section of the pool, from top to bottom. Scrub the acid vigorously.
  7. After approximately 30 seconds, rinse away the acid with the hose.
  8. Drain the diluted acid and soda ash mixture from the bottom of the pool. Refill the pool with water, adding chlorine as necessary.

Safety is essential, so ensure you wear overalls, rubber boots, protective glasses, gloves, and a face mask when working with the chemicals. It's a good idea to have someone else helping you, in case of an emergency, and also to help rinse off the acid quickly to avoid streaks.
