How to Clean Pool Stains With a Vacuum

Stains on your pool surface can be an eyesore and may lead to bigger maintenance problems if ignored. Knowing how to use a vacuum to remove stains keeps your pool clean, inviting, and easier to maintain.

Identify the Type of Pool Stains

Before cleaning, identify the cause of the stains to choose the best cleaning method.

  • Organic Stains: Leaves, algae, and plant debris leave brown or green marks

  • Metal Stains: Iron, copper, or manganese cause rust-colored or bluish stains

  • Calcium or Scale Deposits: White or gray buildup from hard water leaves rough patches

Quick Tip

Rub a chlorine tablet gently on a small section of the stain. If it lightens, it is likely organic. If not, it may be metal or scale.

Prepare the Pool for Vacuuming

  1. Skim and Brush: Remove floating debris and loosen dirt with a pool brush

  2. Check Water Chemistry: Balanced water reduces new stain formation

  3. Assemble Your Vacuum: Connect the hose, pole, and head to the filtration system

Safety Note

Turn off the pump when attaching your vacuum to avoid air entering the lines.

Vacuuming to Remove Pool Stains

Using a vacuum correctly is key to lifting stains and debris.

  • Move the vacuum head slowly over stained areas

  • Overlap passes to ensure full coverage

  • Focus on stubborn spots and let the suction lift debris gradually

Step-by-Step Manual Vacuuming

  1. Prime the hose to remove air

  2. Attach the vacuum head to the telescopic pole

  3. Lower it into the pool and connect to the skimmer

  4. Vacuum in straight, slow lines, overlapping as needed

Deep Cleaning Stubborn Stains

Some stains require extra attention beyond standard vacuuming:

  • Use a Stain Remover: Apply pool-safe products to target the discoloration

  • Brush Along With Vacuuming: Agitate the stain so the vacuum can pick it up

  • Shock the Pool: Organic stains often fade after a chlorine shock treatment

Dealing With Metal and Scale Stains

  • Add a metal sequestrant if you have recurring metal issues

  • Use a stain eraser or pumice stone for scale buildup

  • Consider a stain and scale prevention product in your weekly maintenance

Preventing Future Pool Stains

Keeping up with pool care can reduce the risk of stains:

  • Skim leaves and debris daily

  • Brush walls and floor weekly

  • Test and balance water chemistry regularly

  • Use a pool cover to prevent new debris accumulation

By vacuuming properly and combining it with routine maintenance, your pool will stay bright, clean, and ready for swimming all season.
