Pool Acid Wash Service
Simi Valley
An acid wash is a powerful and cost effective method to restore the look of your swimming pool without the need for expensive replastering. Over time, pool plaster can develop discoloration and stains caused by algae, minerals, and organic debris. At SoCal Poolfection, our skilled technicians use acid washing to carefully remove these surface blemishes, bringing back the fresh, clean appearance of your pool. It’s an excellent solution for pools that have been neglected, are battling ongoing algae problems, or have stains that routine maintenance just can’t fix.
Acid washing is particularly effective for tackling stubborn algae, including black algae, which can embed itself deep into plaster. By treating the root of the problem, this process helps promote a cleaner, healthier pool environment. When performed by the experienced team at SoCal Poolfection in Simi Valley, acid washing is safe, efficient, and offers long-lasting results that leave your pool looking revitalized with minimal downtime.

Acid Wash Services in Simi Valley – SoCal Poolfection’s Deep Clean Solution
If your pool looks stained, cloudy, or just plain tired, it might be time for an acid wash. At SoCal Poolfection, we offer professional acid wash services in Simi Valley to help bring your pool surface back to life. Acid washing is a deep cleaning process that removes stains, mineral buildup, and algae that regular maintenance can’t handle. When done correctly, it can restore the bright, clean look of your pool plaster and make the entire backyard feel brand new.
Whether you’re dealing with a green pool, tough algae, or discoloration from years of use, our experienced team knows when and how to apply acid washing safely and effectively. We serve homeowners across Simi Valley with honest, dependable pool service and a dedication to doing the job right the first time.
What Is an Acid Wash?
An acid wash is a specialized process used to clean the interior surface of a swimming pool, typically plaster or concrete. It involves draining the pool and applying a mixture of water and muriatic acid directly to the surface. This solution removes a thin layer of plaster, taking with it stains, dirt, algae, and mineral deposits that have built up over time.
It’s not something that should be done frequently, but when your pool is heavily stained or covered in algae, an acid wash can give it a fresh start.
When Should You Consider an Acid Wash?
Here are some signs it might be time to schedule an acid wash:
-
Your pool is green and hasn’t responded to chemical treatments
-
You see brown, yellow, or black algae stains embedded in the plaster
-
The water is cloudy even after cleaning and balancing
-
Your plaster looks dull, blotchy, or discolored
-
There is calcium scale buildup on the tile or plaster
If your pool needs to be drained for any reason, such as equipment replacement or extensive repairs, it’s the perfect time to add an acid wash. Since the pool is already empty, we can clean the surface thoroughly and make sure it’s spotless before refilling.
Understanding Algae: Green, Yellow, and Black
Algae is one of the most common reasons pool owners call us. It’s not only unsightly, but it can also affect your water quality and damage your plaster over time.
Green Algae is the most common. It spreads quickly and can make the water look cloudy or bright green. It floats in the water and sticks to walls and steps. In early stages, it can be treated chemically, but when it gets out of control, a full acid wash may be needed.
Yellow Algae, also called mustard algae, is more stubborn. It looks like a yellow or brownish dust and usually forms in shaded areas. It’s resistant to normal chlorine levels and often returns even after brushing. Acid washing removes it from the plaster pores.
Black Algae is the hardest to kill. It appears as small black spots and digs deep into the plaster. It resists brushing and chemicals. In many cases, acid washing is the only way to kill it at the root.
Acid Wash vs. Chlorine Wash: What’s the Difference?
Both chlorine and acid washes are used to deep clean pool surfaces, but they are used in different situations.
Chlorine Wash:
-
Uses liquid chlorine to kill algae and bacteria
-
Best for green pools with organic stains
-
Gentler on plaster
-
Ideal if surface stains are light
Acid Wash:
-
Uses muriatic acid to strip a thin layer of plaster
-
Removes mineral stains, calcium buildup, and embedded algae
-
More aggressive cleaning method
-
Ideal for tough stains and discolored plaster
If you’re unsure which method is right for your pool, our team at SoCal Poolfection can inspect the surface and recommend the best option. In general, a chlorine wash is best for a light-to-moderate green pool, while an acid wash is the better choice for heavy staining and black algae.
Benefits of an Acid Wash
An acid wash does more than just clean your pool it transforms it. Here are some of the top benefits:
-
Removes Stains: Eliminates discoloration from algae, leaves, rust, and minerals.
-
Kills Algae at the Root: Especially helpful for black and yellow algae.
-
Improves Appearance: Restores the original bright look of your plaster.
-
Prepares for Refill: A great reset before adding fresh water.
-
Increases Home Appeal: A clean pool adds value to your home and makes the backyard more enjoyable.
Perfect Time for Tile and Calcium Cleaning
If you have calcium buildup on your pool tile, the best time to clean it is while your pool is empty for an acid wash. Our team can remove the scale from tile and grout using safe, professional methods that protect your tile and make it shine like new.
Combining acid washing with tile cleaning ensures a full refresh for your entire pool area. It’s a smart way to get everything done at once while saving time and hassle.
Safe and Professional Service You Can Count On
Acid washing involves working with strong chemicals, so it’s a job best left to professionals. At SoCal Poolfection, we follow strict safety protocols to protect your pool surface, landscaping, and nearby structures. Our trained technicians use high-quality equipment and proper gear to complete the job quickly and safely.
We also handle all local water discharge regulations, so you don’t have to worry about where the drained water goes.
