How to Remove Stains from Swimwear: A Step-by-Step Guide

Quick Answer

To remove stains from swimwear, rinse the suit immediately in cold water, then treat the stain with a gentle stain remover or mild detergent. Avoid hot water, bleach, and wringing. For tough stains like sunscreen or chlorine, soak in a solution of cold water and a small amount of gentle detergent before washing by hand with a soft cloth.

Swimwear takes a beating from sun, salt, chlorine, and the very products designed to protect you. Sunscreen, tanning oils, and even makeup can leave unsightly marks on your favorite bikini or one-piece. The good news: most stains can be lifted with the right technique and a bit of patience.

In this guide, we’ll walk you through a simple, effective process for removing common swimwear stains without damaging the fabric. You’ll learn how to clean swimwear properly, avoid common mistakes, and keep your suits looking vibrant for many seasons.

Understanding Swimwear Stains

Swimwear fabrics are often delicate and can react badly to harsh chemicals. Sunscreen and tanning products contain oils and UV filters that can cling to fibers and cause yellowing or discoloration. Chlorine, on the other hand, can fade colors and weaken elasticity over time. Salt water and sweat can also leave residues that attract dirt.

Knowing what type of stain you’re dealing with helps you choose the right treatment. Oil-based stains like sunscreen need a degreasing agent, while mineral stains like chlorine may require a gentle soak. Always check the care label on your swimwear for specific instructions, and test any stain remover on an inconspicuous area first.

• Act fast: the sooner you treat a stain, the easier it is to remove.
• Never use hot water on swimwear as it can set stains and damage elasticity.
• Avoid bleach and fabric softeners—they can break down elastane and fade colors.

Step-by-Step Stain Removal Process

Follow these steps to effectively remove stains from your swimwear. Remember to be gentle and avoid scrubbing too hard, as this can damage the fabric.

Start by rinsing the suit in cold water immediately after wearing. This helps remove surface dirt and prevents stains from setting. Then, apply a small amount of mild detergent or stain remover directly to the stain and gently work it in with your fingers or a soft brush. Let it sit for 10-15 minutes, then rinse thoroughly with cold water.

• For stubborn stains, create a soak with cold water and a capful of gentle detergent. Submerge the suit for 30 minutes, then rinse.
• If the stain persists, repeat the treatment before washing the suit by hand in cold water.

Washing and Drying Your Swimwear

After treating stains, wash your swimwear by hand in cold water with a mild detergent. Gently squeeze the water out without wringing or twisting, as this can damage the fabric’s shape and elasticity.

Rinse thoroughly to remove all soap residue, then lay the suit flat on a clean towel to dry. Avoid hanging it in direct sunlight, as UV rays can fade colors. Never put swimwear in the dryer—heat can melt the fibers and ruin the fit.

• Use a dedicated swimwear detergent if you swim frequently—it’s formulated to be gentle and protect colors.
• Roll the suit in a towel to absorb excess water instead of wringing.

5-Step Stain Removal Routine

1. Rinse immediately: Rinse your swimwear in cold water as soon as you get out of the pool or ocean. This removes chlorine, salt, and loose particles before they settle into the fibers. Checkpoint: If you can’t rinse right away, keep your suit in a plastic bag with a little water to prevent stains from setting.
2. Treat the stain: Apply a small amount of gentle stain remover or liquid detergent directly to the stain. Gently rub with your fingers or a soft cloth. Avoid scrubbing too hard to prevent fabric damage. Checkpoint: Always test on an inconspicuous area first to ensure the product doesn’t discolor the fabric.
3. Soak if needed: For stubborn stains like sunscreen or chlorine, soak the suit in cold water with a capful of gentle detergent for 30 minutes. This helps lift oils and chemicals from the fibers. Checkpoint: If the stain is oil-based, use a drop of dish soap—it breaks down oils effectively.
4. Hand wash gently: Wash the suit by hand in cold water with mild detergent. Swish it gently, then rinse thoroughly until no soap remains. Checkpoint: Never use hot water or bleach, as these can set stains and damage elasticity.
5. Dry flat away from sun: Lay the suit flat on a towel, roll it up to absorb excess water, then unroll and lay it flat to dry in the shade. Avoid hanging and direct sunlight. Checkpoint: Ensure the suit is completely dry before storing to prevent mildew.
