Rust stains on pool plaster can mar the appearance of your swimming pool, turning what should be a sparkling oasis into a less inviting space.
These stains usually occur due to metal objects left in the pool for an extended period, metal components of the pool itself corroding, or from the local water supply if it is high in iron.
Fortunately, removing rust stains from pool plaster is a task that can be tackled with the right approach and some elbow grease.
In this guide on how to get rust off pool plaster, we will explore the steps and methods to effectively remove rust from pool plaster, restoring your pool’s pristine condition and ensuring it remains a focal point for relaxation and entertainment.
What is Pool Plaster?
Before we delve into the methods of removing rust from pool plaster, it is essential to understand what pool plaster is. Pool plaster is a cement-based coating used to create a smooth, waterproof surface on the walls and floor of a swimming pool.
This surface helps to seal and protect the underlying structure of the pool while also providing a visually appealing finish.
You may be wondering why pool plaster is susceptible to rust stains. Despite its waterproof properties, pool plaster is still a porous material. This means that it can absorb and retain moisture, especially if the pool water has a high concentration of minerals or chemicals.
When metal objects are left in the pool or metal components of the pool corrode, they leave behind iron oxide, which is responsible for the rust stains on pool plaster.
Why Does Rust Need to Be Removed?
Aside from being unsightly, rust can also cause damage to your pool plaster over time.
As rust stains penetrate deeper into the surface of the plaster, the damage can become irreversible, requiring costly repairs or even replacement of the plaster.
Additionally, rust can also affect the pool’s water chemistry, making it difficult to maintain a proper balance.
If left untreated, rust can also spread to other areas of the pool, such as metal fixtures and equipment, leading to more extensive damage. Therefore, it is crucial to address rust stains on pool plaster as soon as possible to prevent further damage and maintain the overall aesthetic and functionality of your pool.

8 Easy Step-by-step Guidelines on How to Get Rust Off Pool Plaster
Step 1: Drain the Pool
The first step in removing rust stains from pool plaster is to drain the pool. This will allow you to have better access to the affected areas and also prevent any of the cleaning solutions from being diluted or diluted by pool water.
The pool should be drained to the level of the rust stains. It is not necessary to drain the entire pool. You can use a submersible pump or siphon to drain the water. But do not drain more than half of the water to avoid any damages.
Step 2: Mix Cleaning Solution
After draining the pool to the appropriate level, the next step is to prepare the cleaning solution that will be used to tackle the rust stains. If using white vinegar, mix an equal part of vinegar with water in a bucket. For more stubborn rust stains, you can use pure vinegar for a stronger solution.
Alternatively, prepare a paste by mixing baking soda with a small amount of water or lemon juice to achieve a thick consistency. Ensure the solution or paste is well mixed before proceeding to the next step. This mixture will help in breaking down and lifting the rust stains from the plaster surface.
Step 3: Apply the Cleaning Solution
Once your cleaning solution or paste is ready, apply it directly onto the rust stains. If you’re using vinegar or lemon juice solution, you can pour it over the stains or use a sponge or brush to apply it, ensuring the area is thoroughly covered.
For pastes made from baking soda and lemon juice or water, use a nylon brush or sponge to spread the mixture over the rust stains.
Allow the solution or paste to sit on the stains for at least 30 minutes.
For more stubborn stains, it may be beneficial to leave it for up to an hour to allow the acidic solution to penetrate and break down the rust more effectively. During this time, the solution will work to dissolve the iron oxide, making the rust easier to remove.
Step 4: Scrub the Stains
After allowing the cleaning solution or paste to sit on the rust stains for the designated time, it’s time to start scrubbing.
Using the pool brush or scrubber with stiff bristles or a nylon brush, begin to gently scrub the stained areas in a circular motion. The goal is to lift and remove the rust stains without damaging the plaster.
For more persistent stains, applying additional pressure may be necessary, but always be cautious to avoid scratching or harming the surface of the pool plaster.
If you’re dealing with particularly stubborn rust stains, reapply the cleaning solution or paste and allow it to sit for another 30 minutes before attempting to scrub again.
Through patience and careful scrubbing, you should notice the rust stains beginning to fade or completely disappear.
Step 5: Rinse the Plaster
Once the rust stains have been thoroughly scrubbed and removed, the next step is to rinse the plaster surface.
Use clean, fresh water to wash away any remaining cleaning solution, paste, or loosened rust particles. If you have a garden hose, it can be an effective tool for rinsing the plaster, offering a steady and forceful water flow to ensure all residues are cleared away.
Be sure to rinse the area comprehensively, as any leftover cleaning agents or rust particles can cause further staining if not fully removed. After rinsing, inspect the plaster to ensure all rust stains have been eliminated. If any stains persist, you may need to repeat the cleaning process on those specific areas.
Step 6: Refill the Pool
After ensuring that all rust stains have been successfully removed and the plaster surface is thoroughly rinsed, the final step is to refill your pool. Before doing so, inspect the pool for any damages or leaks that may have been exposed or caused during the cleaning process.
If the pool is clear of any such issues, proceed to refill it using a hose or water truck, depending on the size of your pool and available resources.
It is important to monitor the water chemistry as the pool refills and make any necessary adjustments to pH, alkalinity, and chlorine levels to ensure the water is safe for swimming.
Refilling the pool can take several hours or more, so plan accordingly. Once filled, allow the pool’s filtration system to run continuously for at least 24 hours to ensure the water is properly circulated and treated before using the pool again.
Step 7: Prevent Future Rust Stains
To prevent future rust stains in your pool, it’s important to regularly maintain both the water chemistry and the pool’s physical structure. Ensure that the pH, alkalinity, and chlorine levels are checked weekly and adjusted as necessary to keep the water balanced.
This not only provides a safe swimming environment but also reduces the risk of rust formation.
Additionally, inspect the pool for any signs of metal objects, including toys, tools, or equipment, that could corrode and leave rust stains. Remove these objects from the water when not in use.
Using a sequestrant or metal chelator can also be helpful as they bind with metals, like iron, to prevent them from depositing on the pool surfaces. Regular pool maintenance, careful observation, and immediate action if metals are introduced to the water, can significantly diminish the likelihood of rust stains reappearing.
Step 8: Enjoy Your Clean Pool
With the rust stains successfully removed and preventive measures in place, it’s time to enjoy your clean and sparkling pool once again. Regular maintenance and prompt attention to any potential sources of rust will help keep your pool looking its best for years to come.
