What is silicone?

Silicone is straight up amazing! It is far superior to plastic, more durable, and more ocean-friendly than plastic. It lasts longer and stands up better against heat and cold than plastics. Because it’s completely inert and safe to heat to super high temperatures, it’s safe to use for both cold and hot drinks. It’s also safer for your family, too, with no toxic chemicals like BPA to worry about.

All GoSili items are 100% silicone. It is stain-resistant, hypoallergenic, and has no open pores to harbor harmful bacteria. The company is dedicated to building a social movement away from toxic and unsustainable plastic wares by providing the alternative to them. With the excessive amount of plastics linked to negative health and environmental issues, GoSili is creating a cultural shift away from the overuse of these “throw away” plastics.

Is silicone plastic?

NO way dude. Silicone is a type of rubber that is free of toxic chemicals and is built to last, withstand extreme temperatures, endlessly reusable, soft and pliable and is inert.

Are my GoSili products dishwasher safe?

Yes! Every GoSili product is dishwasher safe on both the top and bottom rack. We recommend GoSili cup tops and lids to go on the top rack of the dishwasher to ensure they do not fall to the bottom. If you have an OH Cup Lid, we recommend turning it inside out to clean (either by hand or in the dishwasher).

Are my GoSili products microwave safe?

Yes! Every GoSili product is microwave safe.

Do I need a brush to clean my reusable straw?

No need for a brush! Simply place your straw in the dishwasher. No dishwasher? No problem! To wash the straw by hand, place a drop of soap in the opening of the straw. Roll the straw between two fingers and rinse until the water runs clear.

How long will liquids stay hot or cold in the cups?

The temperature control is similar to glass and ceramic cups. Since the cups are microwave safe, you can pop it in the microwave for a quick reheat!

How are the cups microwave safe with the stainless-steel ring embedded around the top of cup?

GoSili cups are completely safe to use in the microwave. Because the metal is circular the electrons within the metal continue to move within a circular motion, rather than building up on a sharp edge such as a fork which would cause sparks and damage your microwave.

Where’s the opening on the spout of my universal sippy top?

By the nature of silicone many scores and slits in the material seem as though they are not there. However, if you pull on the sides of the sippy spout, you will notice that the opening will appear. Upon first use, give the sides a good pull and the spout will work great!

Can silicone products absorb smells?

Liquids with strong odors – like coffee – may cause a lingering effect. But not to worry! If this happens, here are some ways to remedy the situation: rinse with hot water after each use rub with white vinegar or lemon to stabilize the odor soak in baking soda and hot water run through dishwasher.
