Quick answer

A mild, temporary odor from a new silicone toy is normal and usually fades after a few washes. Persistent or strong smells often come from absorbed body oils, trapped moisture, or improper storage. You can remove most odors with a simple baking soda paste or a thorough wash with mild soap and warm water.

Why silicone toys can develop an odor

Silicone is naturally non-porous and resistant to absorbing odors, but it can still pick up smells from body fluids, lubricants, or the packaging itself. New toys sometimes have a faint factory scent that dissipates quickly. If the smell lingers after a few uses, it's usually because oils or residues have been trapped on the surface or in tiny crevices.

Another common cause is storing the toy in a sealed plastic bag or a closed drawer without airflow. Moisture and warmth create a breeding ground for bacteria, which can produce a musty or sour odor. Silicone itself does not harbor bacteria, but surface residues can.

How to safely remove odor from silicone toys

Start with a simple wash: use mild, fragrance-free soap and warm water. Scrub the entire surface with your hands or a soft cloth, paying attention to ridges or textured areas. Rinse thoroughly and pat dry with a clean towel. This removes most surface residues.

If the smell persists, make a paste of baking soda and a little water. Apply it to the toy, let it sit for 10–15 minutes, then rinse and wash again. Baking soda neutralizes odors without damaging silicone. Avoid using vinegar, bleach, or alcohol, as these can degrade silicone over time or leave behind a smell of their own.

For stubborn odors, you can place the toy in a well-ventilated area for a few hours after cleaning. Sunlight can help, but avoid prolonged direct sun exposure, which may discolor or degrade the material. Never boil or dishwasher-clean a silicone toy unless the manufacturer explicitly says it's safe, because high heat can warp or damage the silicone.

When to stop cleaning and consider replacement

If you've cleaned the toy thoroughly and the odor remains strong or changes to a chemical or burnt smell, stop using it. A persistent chemical odor could indicate that the material is not pure silicone or that the toy has been damaged. Check the manufacturer's care instructions. Tantus toys are made from 100% Ultra-Premium Silicone, which is hypoallergenic and hygienic, so they should not develop a lasting chemical smell under normal use.

Also inspect the toy for cracks, tears, or sticky spots. Any physical damage can trap residues and bacteria, making the odor impossible to remove safely. In that case, it's time to retire the toy and replace it with a new body-safe option.

Diagnosis: Is the smell normal or a warning sign?

  • Symptom: Faint, plastic-like or 'new toy' smell right out of the package. Normal. Wash with mild soap and warm water; the smell should fade after 1–2 washes.
  • Likely cause: Residual oils, lubricant, or body fluids on the surface after use. Wash the toy immediately after each use with soap and warm water to prevent buildup.
  • Corrective action: Make a baking soda paste, apply to the toy, let sit for 10–15 minutes, then rinse and wash again. If the smell disappears, the toy is safe to use. Continue regular cleaning.
  • Stop or replace: Strong chemical or burnt smell, or odor that persists after multiple cleaning attempts. Stop using the toy. Check for damage. If the toy is cracked or sticky, replace it with a new body-safe silicone toy.
