FAQ: Washing, Yellow Stains, and the Sauna
How often should swimwear be washed, and can it be tumble-dried?
Swimwear should be rinsed in cold water after each use to remove chlorine, salt, and sunscreen, which break down the fibers over time. A full wash with a mild detergent for delicate fabrics is recommended after the swimwear has been worn several times or has been exposed to a lot of chlorinated water. Hand washing is preferable to machine washing, as the gentle treatment helps preserve elasticity and shape for longer.
Tumble drying is generally not recommended for swimwear. The heat from the dryer breaks down the elastane fibers, which are essential for the fit, and can cause the material to lose its elasticity. Instead, it’s recommended to hang the swimwear to dry, preferably in the shade, as direct sunlight can fade the colors over time.
How do I prevent yellow stains on my swimwear?
Yellow stains on swimwear typically result from a combination of sweat, sunscreen, chlorine, and heat, which react with the fibers over time. The most effective prevention is to rinse your swimwear in cold water immediately after use, so that residues don’t have time to set in. Sunscreen should, whenever possible, be applied well in advance of putting on your swimwear, so that it absorbs into the skin rather than transferring directly to the fabric.
If discoloration does occur, you can try a mild, oxygen-based stain remover designed for delicate fabrics. It is also recommended to avoid tumble drying, as heat can permanently set a stain in the fibers.
Should swimwear fit snugly, and can you wear it in a sauna?
Swimwear should fit snugly against the body without being too tight. Since the material—typically a blend of polyamide or polyester and spandex—expands slightly upon contact with water and during use, people often choose a size that feels slightly snug when the swimwear is dry and new. A fit that’s too loose increases the risk of the swimwear shifting or losing its shape after repeated use.
Whether you’re allowed to wear swimwear in a sauna depends on the specific venue’s rules. Some swimming pools and sauna clubs allow swimwear, while others enforce a policy based on hygiene and technical considerations, as wet swimwear can, among other things, damage the wood in the sauna. It is recommended that you familiarize yourself with the guidelines of the facility in question and, as a general rule, always sit on a towel in the sauna, regardless of whether you are wearing swimwear or not.
