Why Do Rust Stains Appear in Pools?

Rust stains typically appear as reddish-brown discolouration on pool surfaces and can stem from several sources:

• Metal objects accidentally dropped into the pool (hairpins, toys, tools)

• Corroding metal pool components (ladders, handrails, light fittings)

• Iron content in source water, particularly from bore water

• Metal equipment in contact with pool chemicals

• Deteriorating internal pool equipment, like heaters or pumps

Identifying Rust Stains

Before treatment, confirm you're dealing with rust rather than algae or other stains. Rust stains:

• Appear as reddish-brown or orange marks

• Don't brush off easily

• Often form in specific patterns related to metal contact

• May reappear in the same location if the source isn't addressed

Effective Rust Stain Removal

Step 1: Test and Balance Your Water

Start by testing your pool water chemistry. Imbalanced pH levels can contribute to metal oxidation and make stain removal more difficult. Aim for:

• pH between 7.2 and 7.6

• Total alkalinity between 80-120 ppm

• Calcium hardness between 200-275 ppm

Step 2: Apply a Specialised Rust Remover

Our Stain Removal products are specifically formulated to dissolve rust stains without damaging pool surfaces. For best results:

1. Apply directly to the stained area

2. Allow the product to work for the recommended time (usually 10-15 minutes)

3. Gently scrub with a non-abrasive brush

4. Rinse thoroughly

For stubborn stains, a second application may be necessary.

Step 3: Prevent Future Staining

Once you've removed the stains, take preventative measures:

• Add a metal sequestrant to your regular pool maintenance routine

• Remove metal objects from the pool promptly

• Inspect and maintain metal pool components regularly

• Consider using a pre-filter when filling your pool with bore water

• Install sacrificial anodes if metal staining is a recurring issue
