Quick answer

Rinse your bikini in cool water immediately after every wear, wash it gently by hand with a mild detergent, and lay it flat to dry away from direct sun. Store it flat or folded, not stretched on a hanger. These habits keep elastic and prints intact so your swimwear looks new for many seasons.

You’ve found a bikini that fits perfectly and makes you feel great. Now you want to keep it that way. Sunscreen, chlorine, salt, and even body oils can break down swimwear fabrics over time, but a few simple habits will protect your investment.

This guide walks you through the exact steps to clean, dry, and store your swimwear so it stays in shape. We’ll also point out common mistakes that shorten a bikini’s life and show you how to avoid them.

Why swimwear needs special care

Swimwear is typically made from elastane blends that give it stretch and recovery. Chlorine, salt, sunscreen, and heat degrade these fibers, causing sagging, fading, and loss of shape. Hand washing and air drying are the easiest ways to prevent that damage.

Even if your bikini is handmade with high-quality materials, it still needs gentle handling. The O rings, adjustable straps, and lined fronts on styles like the Venom Spark Bikini Bottoms can snag or warp if washed roughly. Treat each piece like delicate lingerie, not like a towel.

  • Avoid washing machines and dryers—they are the fastest way to ruin stretch.
  • Never wring or twist your bikini; it damages the fabric and hardware.

Step-by-step swimwear care routine

Follow these steps every time you wear your swimwear to keep it fresh and extend its life. Each step includes a common mistake to watch for so you can correct it right away.

Remember that handmade items may have unique trims or limited materials, so always check the care instructions that came with your purchase. If in doubt, hand wash and air dry.

  • Rinse immediately after wearing—don’t let damp swimwear sit in a bag.
  • Use a gentle swimwear detergent or a tiny amount of mild soap.
  • Lay flat to dry in the shade; hanging can stretch straps.

Your 5-step bikini care routine

  1. Rinse immediately after wearing: As soon as you take off your bikini, rinse it in cool water to remove chlorine, salt, and sunscreen. Use a gentle stream, not a forceful jet. Common mistake: leaving it rolled up in a wet towel or bag, which encourages mildew and set-in stains. Checkpoint: Rinse before it dries completely.
  2. Hand wash with mild detergent: Fill a basin with cool water and add a drop of gentle swimwear detergent or baby shampoo. Submerge your bikini and gently squeeze the water through the fabric. Never rub or scrub. Common mistake: using regular laundry detergent or bleach, which can break down elastic and fade colors. Checkpoint: If the water looks dirty, repeat with fresh water until clear.
  3. Rinse thoroughly and remove excess water: Drain the soapy water and rinse your bikini under cool running water until no suds remain. To remove excess water, lay it flat on a clean towel and roll the towel up, pressing gently. Do not wring or twist. Common mistake: twisting the bikini like a rag, which stretches and weakens fibers. Checkpoint: The towel should absorb most of the water; the bikini should feel damp, not dripping.
  4. Lay flat to dry in the shade: Reshape the bikini and lay it flat on a dry towel or drying rack away from direct sunlight and heat sources. If drying outdoors, choose a shaded spot. Common mistake: hanging by the straps, which can stretch them out, or drying in direct sun, which fades colors and damages elastic. Checkpoint: Ensure air circulates around the bikini; flip after a few hours if needed.
  5. Store flat or folded, not stretched: Once completely dry, store your bikini flat in a drawer or folded in a breathable bag. Avoid hanging it by the straps for long periods. Common mistake: storing damp swimwear in a plastic bag, which traps moisture and causes mildew. Also, keep it away from rough surfaces that can snag O rings or hardware. Checkpoint: Store separately from heavy items to prevent snags.

Product care notes

  • Venom Spark Bikini Bottoms: O ring details, lined front and fully adjustable straps. The O rings and adjustable straps can snag or bend if washed with heavy items. Hand wash separately and fasten straps before rinsing to prevent tangling.
  • Sinister Sapphire O Ring Bikini Bottoms or Thong: High waist bikini bottoms with O rings to the sides, fully lined in the front and edged in elastic for comfort. The elastic edging and O rings need gentle handling. Avoid pulling or stretching the sides when cleaning; support the fabric and rinse without wringing.
  • Watermelon Bikini Bottoms: Lined in the front with soft elastic banding around all edges for a luxury finish. The soft elastic banding can lose recovery if exposed to heat. Always dry flat away from radiators or direct sun to maintain the fit.

With these simple steps, your bikini will stay in great shape season after season. Remember to rinse after every wear, hand wash gently, and dry flat in the shade. Your handmade swimwear deserves that little extra care, and it will reward you with a perfect fit every time.
