Identify the Type of Stain on Your Pool Plaster
Organic Stains
Organic stains come from natural sources like leaves, twigs, and other vegetation that fall into your pool. These stains are usually green or brown and can be slimy or powdery. If you have trees or bushes close to your pool, you’re more likely to experience organic stains.
Bleach is one of the best solutions for removing organic stains. Simply mix one part bleach with three parts water, apply the solution to the stain, and let it sit for a few minutes. Then, scrub the area with a brush and rinse thoroughly with water.
Vitamin C is another effective solution for organic stains. Crush up vitamin C tablets or use a vitamin C solution and apply it directly to the stain. Let it sit for a few minutes and then scrub the area with a brush. Rinse thoroughly with water.
If the stain is particularly stubborn, you may need to use a stain-removing product specifically designed for organic stains. Be sure to follow the product instructions carefully and wear protective gloves and eyewear.
Prevention is key when it comes to organic stains. Keep your pool area clear of debris, and consider installing a pool cover to protect your pool from falling leaves and twigs.
Metal Stains
Metal stains are a common problem for pool owners, and they can be caused by a variety of metals, including copper, iron, and manganese. Here are some tips for identifying and removing metal stains from your pool plaster:Identify the Source of the Stain
Before you can remove metal stains from your pool plaster, you need to know what type of metal is causing the problem. If you have a copper stain, it may be caused by copper in your pool water or copper-based algaecides. If you have an iron stain, it may be caused by iron in your pool water or iron-based products used to treat your pool.Use a Metal Sequestrant
A metal sequestrant is a chemical that binds to metals in your pool water, making them less likely to stain your pool plaster. Be sure to follow the manufacturer’s instructions when using a metal sequestrant, as using too much can cause other problems.Try an Ascorbic Acid Treatment
Ascorbic acid is a powerful oxidizing agent that can break down metal stains on your pool plaster. To use an ascorbic acid treatment, you’ll need to lower your pool’s pH to around 7.2, then add the treatment to your pool water. Follow the manufacturer’s instructions carefully.Use a Stain Remover

Choose the Right Cleaning Solution for Your Pool
Before you start removing stains from your pool, it’s essential to choose the right cleaning solution. Using the wrong product can cause further damage to your pool’s plaster. Look for products that are specifically designed for removing pool stains, and always follow the manufacturer’s instructions.
Acid-based solutions: If you’re dealing with mineral or metal stains, an acid-based solution can be effective. These solutions contain hydrochloric or muriatic acid, so be sure to wear protective gloves and goggles when using them. Always add acid to water, never water to acid, and never mix different types of acid-based products.
Chlorine-based solutions: Chlorine-based products are effective for removing organic stains such as algae and mildew. They work by oxidizing and breaking down the organic material. Be sure to use the correct concentration of chlorine, as too much can damage your pool’s plaster.
Natural solutions: For a more eco-friendly approach, you can try using natural solutions such as baking soda or white vinegar. These solutions can be effective for removing light stains and are less harsh on your pool’s plaster. However, they may not be as effective as acid or chlorine-based solutions for tougher stains.
Enzymatic solutions: Enzymatic cleaners use natural enzymes to break down organic material in your pool. They are an effective option for removing organic stains and are less harsh than chlorine-based solutions. However, they may not be as effective for mineral or metal stains.
Determine the Type of Stain and Select the Appropriate Cleaning Product
Before you begin cleaning your pool, it’s important to determine the type of stain and select the appropriate cleaning product. For organic stains, you’ll need an enzyme-based cleaner like natural pool enzymes. For metal stains, use a metal sequestrant to prevent the metals from discoloring your pool water. For mineral stains, a citric acid-based cleaner or ascorbic acid will work well.
It’s important to read the label of your cleaning product and follow the instructions carefully. Some cleaners may require a longer soaking time or multiple applications for best results.
When selecting a cleaning product, consider using a product that is safe for both your pool and the environment. Look for cleaners that are biodegradable and free from harsh chemicals.
Be sure to wear protective gear such as gloves and eye protection when handling cleaning products, and always store them in a cool, dry place out of reach of children and pets.
