The Ultimate Guide to Cleaning & Removing Pool Stains


Having a clean, sparkling pool isn't just about aesthetics—it’s also important for maintaining water quality and ensuring your pool stays in top condition for years to come.

Why Do Pool Stains Appear?

Before removing pool stains, it’s essential to understand what causes them. Stains can occur for numerous reasons, including:

  • Metal Contamination: Metals, such as copper, iron, or manganese, often seep into pool water through pool equipment, pipes, or even well water.
  • Organic Matter: Falling leaves, algae, dirt, or debris can lead to organic stains if left unattended for an extended period.
  • Chemical Imbalance: Unbalanced water chemistry can cause certain materials to react in ways that discolor pool surfaces.
  • Hard Water and Calcium Deposits: High levels of calcium or minerals in the water can leave behind stubborn, chalky stains.

Knowing the source of your stains can make it easier to tackle them effectively.
 

Types of Pool Stains

Not all pool stains are created equal! Here’s a quick rundown of the most common types and how to identify them:

1. Metal Stains

  • Appearance: Ranges from reddish-brown to black or green-blue streaks.
  • Source: Metals like iron, manganese, or copper. These stains commonly result from deteriorating pool equipment or water sources with high mineral content.

2. Organic Stains

  • Appearance: Green, yellow, or brown patches.
  • Source: Leaves, algae, berries, or other organic debris that sits on the surface for too long.

3. Rust Stains

  • Appearance: Orangish-brown marks that often look like rust spots.
  • Source: Screws, rebar, or metal objects left in the pool.

4. Calcium Buildup

  • Appearance: White, flaky deposits that often form on the waterline or around tiles.
  • Source: Hard water or improper balancing of chemicals like calcium hardness and pH.
     

Steps to Clean and Remove Pool Stains

1. Identify the Type of Stain

The first step in cleaning pool stains is determining their type. Perform a simple test by sprinkling ascorbic acid (Vitamin C) or a pool stain remover over the stained area.

  • If the stain lightens or disappears after a few minutes, it’s likely due to metal contamination.
  • If there’s no visible change, then you may be dealing with an organic stain or a buildup like calcium.

2. Test and Balance Your Water

Unbalanced water chemistry can worsen stains or cause new ones to appear. Use a pool water test kit to check the following levels:

  • Chlorine
  • pH
  • Total Alkalinity
  • Calcium Hardness
  • Metals

Aim to keep pH between 7.4 and 7.6 while ensuring proper balance of chlorine and metals. Here in Winter Park, hard water is fairly common, so calcium levels require special attention.

3. Scrub the Stains

For light staining, scrubbing with a stiff-bristle pool brush is often sufficient. Use a cleaner compatible with your pool’s surface material, whether it’s vinyl, fiberglass, or concrete.

💡 Pro Tip: Add baking soda directly to your pool brush to provide extra scrubbing power for stubborn organic stains.

4. Use Pool Stain Removers

Store-bought stain removers are specially designed to target specific stains. When purchasing a stain remover:

  • Opt for metal stain removers if your stain is due to metals.
  • Choose organic stain treatments for stains caused by leaves and dirt.

Follow the product directions carefully.

5. Shock the Pool

For stains due to algae or dirt, “shocking” your pool can help. Pool shock raises chlorine levels and sanitizes the water, effectively breaking down organic contaminants.

  1. Calculate the correct amount of pool shock needed for your pool size.
  2. Add shock treatment in the evening to allow overnight stabilization.
  3. Brush the pool and run the filtration system for at least 24 hours.

6. Prevent Calcium Buildup

Calcium buildup can be minimized with the use of descalers, which break up hard water deposits. Additionally, keeping your calcium hardness balanced (between 200 and 400 ppm) will prevent further scales and stains.
 

Tips for Preventing Future Pool Stains

An ounce of prevention is worth a pound of cure! Incorporate these tips into your maintenance routine to prevent stains from forming:

  1. Regular Cleaning and Skimming:

Remove leaves and debris from the water daily. Regular vacuuming ensures no dirt gets time to settle.

  1. Monitor Metal Levels:

Use a professional-grade sequestrant chemical to control metals like iron and copper in your pool.

  1. Balance Your Water Chemistry:

Keep chlorine, pH, and alkalinity levels within their recommended ranges. Test your water regularly, or have it done by experts like Pure & Simple Poolcare in Winter Park, FL.

  1. Upgrade Pool Components:

Older pool equipment can leach metals into the water over time. Consider upgrading to newer, high-quality materials to avoid this problem.

  1. Schedule Professional Maintenance:

Expert pool services can ensure your water remains balanced consistently, reducing the likelihood of stains, buildup, and algae blooms.
