Could Your Pool Towels Be Affecting Your Water Quality?

You throw a towel over your shoulder after every swim. But here is something surprising. Your laundry habits could be affecting your pool or spa water more than you realize.

Residue from detergents, fabric softeners, and dryer sheets can transfer from towels to swimmers, and eventually into the water. Over time, this can contribute to cloudy water and filter buildup.

🧺 How Towels Impact Pool and Spa Water

Laundry products are designed to stay in fabrics, but that means they can also enter your pool or spa water.

Here are a few common issues:

• Fabric softeners leave residue on towels
These coatings transfer onto skin and into the water when swimmers dry off.

• Perfumed detergents can introduce phosphates
Certain detergents leave behind compounds that contribute to algae growth.

• Dryer sheet oils can clog filters
Residues from dryer sheets can accumulate in pool and spa filtration systems.

Soft towels are great, but they should not bring extra chemicals into your soak.

Spa water has much less volume than a pool, so even small residues can affect water clarity quickly.
