Silicone is used to make a number of modern products. Since it has a rubber-like consistency and resists heat, this material can be used to make insulation, cookware, toys, dry cleaning solvents, shampoos, menstrual cups and sex toys, and many other items.
While you may not need to deal with removing smell from silicone in all these applications, this guide will provide you with information you (or a friend) are most likely to be curious about: cookware, menstrual cups, and sex toys.
These cups are constructed with tiny holes, and if they smell funky it's possible that some vaginal fluid or mucus has become trapped in these cavities. The silicone itself shouldn't be the culprit, and you don't necessarily need to throw the cup away. To get rid of the smell, you will need to get a needle or a pin and excavate these holes to remove any buildup of material. Once you've finished, boil the cup before using it again.
A buildup of soap residue may be contributing to the funk you are noticing from the cup. Silicone is supposed to be inert, so you should be looking for something outside of the cup as the problem. Clean the cup with Dial Body Wash or Dove soap to try to get rid of this problem.
Another solution to the issue of a smell silicone menstrual cup (after trying the pin thing) is to dilute two drops of tea tree oil in two Tablespoons of water and place your cup in the liquid. Place your cup in the sun or outside for a day. This should get rid of the smell. Boil the cup at the end of the day and rinse with cold water before using it.
Mix up a solution of bleach and water (one part bleach to five parts water) and let it sit in the silicone pan. Follow up by running the bakeware through the dishwasher.
Pay a visit to your local sporting goods store to get an odor eliminator for hunting. Apply the scent eliminator to the silicone bakeware, leave it in and wash thoroughly. The smell should be gone.
A solution of white vinegar and water should get the smell out of silicone and clean your bakeware, too. Mix it up, leave it in overnight and wash as usual.
Tomato juice works on dogs that have been sprayed by a skunk, so it should be able to handle the smell in a silicone pan.
This hands-on approach to getting your silicone sex toys freshened up and ready to go for the next close encounter of the best kind involves using some dishwashing soap first. You can go with an antibacterial one if you want. It won't hurt the silicone, and you are mostly interested in finding a product with grease-cutting properties here. When you are looking for a mechanic's hand cleaner, avoid one that has pumice; that will scratch the toy. Stick with something that is a "goop" instead. Again, think grease cutter to get rid of the stank and you should be good to go.
Baking soda is a good, clean choice for removing stinky smells from all kinds of things, and silicone is no exception. Put a half cup of soda in a gallon of water and throw the toy in. Give it a good soaking. Repeat this part of the cleaning if you don't feel confident that the smell is coming out. The baking soda won't damage the toy at all. Then spray the toy with Febreze. You can also tag-team the spray freshener with a toy cleaner solution if you like.
