What types of products can I put in a GoToob?
The GoToob is designed to work with a wide range of fluids from shampoos and conditioners to facial cleaners and sunscreen. GoToobs are even made of FDA food-safe silicone so you can put soft food products like peanut butter and yogurt in them. While GoToobs are designed for a range of fluids and soft products, it is still possible that you can find an incompatible fluid. This is why we recommend running a trial on all new products -- try only a small amount of the new product overnight in a safe environment where a possible reaction or leak won't damage anything. If you find a new incompatible fluid, please email us. We will add it to the appropriate list of incompatible fluids, and we will be happy to replace your GoToob if it has been rendered unusable.

Why are GoToobs incompatible with some fluids?
While silicone is one of the most impervious materials in common commercial use today, reactions can still occur (no material is completely impervious). The incompatibility often relates to silicone's porous nature (some fluids can seep or evaporate through the pores of the silicone) or a combination of chemicals that causes the silicone to expand. Unfortunately, we can't tell you specific chemicals or ingredients to avoid because it can be a combination of them that causes leaking and reactions. We provide updated lists of non-recommended fluids based on customer reports on our website and offer a lifetime warranty on all our products.

How do I know if my fluid is incompatible?
Your fluid is incompatible if it leaks from the GoToob, changes the shape or color of the silicone tube, evaporates from the tube, or dries up shortly after being put in the tube. Most reactions occur overnight; this is why we recommend an overnight trial run with a new product.

I only want to dispense a small amount of the fluid I put in the GoToob, but a lot comes out. What can I do?
The GoToob has been designed to work with a wide range of fluids -- from soft food products to thin liquid soaps. This means that the valve has been designed to dispense a wide range of viscosities. We find that the best way to get a small amount of a thin fluid is to squeeze the tube quickly -- the longer the squeeze, the longer the valve is open and thus the more fluid that is dispensed.

What are the care and cleaning instructions for GoToobs?
The tube and collar are dishwasher safe (top rack only). The flip cap can be hand-washed in warm, soapy water.

Can parts of GoToobs be replaced under the lifetime warranty?
Yes. In your warranty request email, please let us know what has happened and what part has been damaged.

How can I make the suction cup on the 2 fl. oz. size stick to the wall longer?
One of the limitations of the silicone material that GoToobs are made out of is that the suction cup only holds temporarily in the best of environments -- when stuck to a clean, smooth, non-porous surface (and the suction cup is moistened). This is why we promote it as "great for moments when you need both of your hands free." It would be great if the suction could hold longer, but unfortunately that is just a limitation of the material itself. While we have been successful with the suctions holding for about a day, all the conditions had to be just right.

Why do some fluids dry up if left in GoToobs for months while some get more watery?
These types of reactions can occur because of the porousness of silicone. While some fluids can dry up, this is usually over several months. Also, we've received reports that adding a small amount of water can restore fluids to their normal state.

Are there multiple styles of GoToobs?
In 2011, we redesigned the collars, which led to a slight change in the tube shape as well. The newer design of collars is a two-piece design (an outer ring unsnaps from the inner ring). The older collar is a one-piece design that can twist around showing the content IDs on the tube itself. We changed the design to allow for a blank space on the inner ring where customers can write in their own content IDs with a Sharpie.
