Prevent Yellowing of SwimwearUpdated 2 months ago

Yellowing of swimwear after use in pools is mainly caused by chlorine, sunscreen, and body oils. Here are the key reasons:

1. Chlorine & Pool Chemicals

  • Chlorine and other pool sanitizers (like bromine) break down fabric dyes over time.
  • Chlorine interacts with elastane (spandex) in swimsuits, causing it to degrade and change color.
  • High chlorine levels can leave a yellowish or greenish tint, especially on white or light-colored swimsuits.

2. Sunscreen & Body Oils

  • Sunscreens containing avobenzone can react with chlorine, forming yellowish stains.
  • Body oils and lotions can bond with chlorine, creating a film on the fabric that traps discoloration.

3. Hard Water & Mineral Buildup

  • If the pool water has high iron or mineral content, it can contribute to yellowing.
  • Minerals from water can accumulate in the fabric and oxidize, leading to discoloration.

4. Improper Washing & Drying

  • Not rinsing your swimsuit immediately after swimming allows chlorine and sunscreen to set in.
  • Air-drying in direct sunlight can worsen yellowing because UV exposure speeds up fabric breakdown.
  • Using harsh detergents or bleach can degrade fibers, making yellowing more noticeable.


How to Prevent Yellowing:

*Rinse immediately after swimming in cold, clean water.

*Hand wash with mild detergent (or a mix of water & white vinegar to neutralize chlorine).

*Avoid wringing out swimsuits, as it damages fibers.

*Dry in the shade, not direct sunlight
