Clean the majority of silicone items by hand with warm or hot water and a mild soap. Most items are dishwasher-safe, although it's recommended to avoid immersing silicone items with internal electrical or mechanical components.
In general, avoid cleaning silicone items with harsh soaps or scouring pads. This tends to degrade the material, causing damage.
One common problem with silicone bakeware is a persistent oily residue left behind that is difficult to remove. Over time, the residue can build up and inhibit the non-stick properties of the material. Clean such a residue by first washing the item in hot water with a grease-cutting soap. Apply a paste of baking soda and water to the still-wet sticky area and gently scrub with a cloth. Leave the paste to dry, then wash the item again in a mild detergent to remove all baking soda.
Silicone rubber is an elastic polymer used in a wide variety of applications due to easy forming and manufacturing. The material, consisting of the elements silicon, hydrogen, carbon and oxygen, withstands a wide range of temperatures. It is strong, inert to a wide range of chemicals, and relatively lightweight. Silicone is commonly found in houseware items, clothing, medical devices and home repair materials.
