No one wants to jump into a pool and find unsightly rust stains on the walls or floor. Rust in a pool can be an eyesore, but it can also signal underlying issues with your pool’s equipment or structure.
Whether the rust comes from metal fixtures, water with high iron content, or debris left in the pool, it’s important to address it quickly to maintain a clean and enjoyable swimming experience.
So let’s find out simple and effective ways to remove rust from a pool –
What Causes Rust Stains in a Pool?
Rust stains can form in your pool for several reasons, and identifying the cause is the first step to preventing them from coming back after you clean. Here are some of the most common causes of rust in a pool:
- Metal fixtures: Ladders, railings, screws, or even metal debris can rust over time and deposit rust stains onto your pool’s surfaces. If these metals corrode and flake, they will leave orange or brownish rust marks.
- High iron content in water: If your water source has a high concentration of iron, it can lead to rust formation in your pool. This is especially common if you’re filling your pool with well water.
- Metallic pool equipment: Sometimes, pool pumps or other equipment have metal components that can rust and cause stains to spread through the water.
- Debris in the pool: Things like metal tools, nails, or other small objects that end up in your pool and go unnoticed can cause localized rust spots if left in the water for too long.
Once you identify the cause, you can take the necessary steps to remove the rust and prevent it from returning. Let’s dive into how to effectively remove rust from your pool using simple techniques and readily available products.
Step-by-Step Guide to Remove Rust from A Pool
To remove rust from a pool, use ascorbic acid or a dedicated rust remover to treat stains, then brush the area and vacuum any debris. Prevent future rust by addressing potential sources like metal pool parts and high iron content in the water.
Removing rust stains from your pool isn’t as difficult as it may seem. The right tools and cleaners can make the job easy and prevent further damage to your pool surfaces.
Step 1: Identify the Source of the Rust
Before you start cleaning, take a moment to inspect your pool to find where the rust is coming from. If it’s caused by metal parts like screws or ladders, you may need to replace or treat those parts to prevent rust from spreading further.
- Check pool fixtures and equipment: Look at metal ladders, railings, screws, and any metallic parts of your pool’s pump or filter system.
- Examine the water source: If you use well water or know that your tap water has a high iron content, consider treating the water to reduce iron levels.
By identifying the source, you can ensure that you’re not just treating the symptoms but also addressing the root cause of the rust.
Step 2: Treat Rust Stains with Ascorbic Acid or a Rust Remover
Ascorbic acid (Vitamin C) is a popular and effective solution for removing rust stains from pool surfaces, and it’s safe for use in pools without affecting water chemistry. Alternatively, you can use a rust remover designed specifically for pools, available at most pool supply stores.
Using Ascorbic Acid:
- Apply ascorbic acid directly to the stain: Sprinkle or place a small amount of ascorbic acid powder on the rust spot. You can also dissolve the powder in water and apply it to the stain using a sponge or brush.
- Let it sit: Allow the ascorbic acid to work for about 5–10 minutes. You’ll notice the stain starting to lighten as the acid breaks down the rust.
- Brush the stain: After the acid has had time to work, gently scrub the stained area with a soft pool brush to lift the remaining rust.
Using a Commercial Rust Remover:
- Follow product instructions: Most commercial rust removers for pools come with specific application instructions. Apply the remover directly to the stain, let it sit, and then scrub with a soft brush.
Pro Tip: Avoid using harsh scrubbing pads or stiff wire brushes, as they can damage the surface of your pool.
Step 3: Brush the Pool Walls and Floor
Once the rust remover or ascorbic acid has broken down the stains, it’s time to give your pool a thorough scrub.
- Use a soft-bristle pool brush: Brush the areas where the rust stains were treated, paying special attention to corners and crevices where rust may be hiding.
- Brush in circular motions: Gentle circular brushing helps lift the stain without damaging the surface of the pool.
This step ensures that any remaining particles of rust or debris are loosened and can be easily removed in the next step.

Step 4: Vacuum and Clean the Pool
After brushing, it’s important to remove any debris or rust particles from the pool. This step prevents the rust from settling again and causing new stains.
- Use a pool vacuum: If you have an automatic pool cleaner, let it run over the treated areas to pick up loose particles. For manual vacuums, carefully vacuum the bottom of the pool to ensure all rust debris is removed.
- Clean the filter: Check and clean your pool’s filter after vacuuming. Rust particles can clog the filter, reducing its efficiency.
This final step ensures that your pool is not only free of rust stains but also thoroughly cleaned of any remaining debris.
Step 5: Test and Balance Your Pool Water
After removing rust, it’s essential to test and balance your pool water to prevent further issues. Rust stains can form due to imbalanced water chemistry, so maintaining proper pH and chlorine levels is key.
- Test for iron and pH levels: Use a pool test kit to check the iron content and pH level of your water. If the iron level is high, consider adding a sequestering agent to help remove metals from the water. Your pH should be between 7.2 and 7.6 to prevent future rust stains.
- Balance your water chemistry: Adjust the chemical levels as needed to ensure your pool water is safe, clear, and rust-resistant.
Preventing Rust Stains in the Future
The next step is prevention once you’ve removed the rust stains from your pool. Here are a few tips to help you keep rust from coming back:
Treat Your Water for Iron
Consider using a sequestering agent if your water source contains high iron levels or other metals. This product binds to the metals in the water, preventing them from oxidizing and causing stains. Adding it regularly to your pool maintenance routine can prevent rust buildup.
Replace or Coat Metal Fixtures
If your pool ladders, screws, or railings are rusting, replace them with stainless steel options or coat them with a rust-proof sealant to prevent corrosion.
Remove Metal Debris Quickly
If any metal objects accidentally fall into your pool—whether it’s tools, hairpins, or other debris—remove them as soon as possible to prevent rust spots from forming.
Monitor Water Chemistry
Regularly testing your water and keeping the pH, alkalinity, and metal levels balanced will help you avoid rust and other staining issues.

End Note
Rust stains in your pool can be frustrating, but they’re not permanent! By using ascorbic acid or a rust remover, scrubbing the affected areas, and vacuuming up debris, you can restore your pool’s pristine appearance in no time. Don’t forget to address the source of the rust—whether it’s metal fixtures, high iron content in the water, or debris—to prevent stains from reappearing.
Keeping your pool clean and free from rust requires regular maintenance, but the results are worth it. With the steps outlined in this guide, you can enjoy a sparkling, rust-free pool all summer long.
