Another method is to add a few drops of paint thinner to the gum to brand it softer, notwithstanding, this might weaken the adhesive properties of the glue.
Keep reading to learn more than about how to soften the glue and how to prevent it from drying in the container.
How Does Glue Dry?
There are various kinds of synthetic glue that are fabricated from dissimilar chemical substances which is why they dry in different ways and at different rates.
White Mucilage or PVA-based glue comprise water in their formula which affects the consistency of the glue. The h2o basically acts as a solvent that keeps the glue in a liquid class until you desire it to stick.
Once you employ the mucilage on a surface, the water will be exposed to air then it will gradually evaporate. When the water evaporates, the glue will harden and dry considering all that will exist left are the sticky base of operations components in the glue, PVA polymers, which will bond with the surface.
Notwithstanding, when the glue is sealed inside the container, it will not exist exposed to enough air to crusade the h2o to evaporate which means the glue will remain in a runny liquid course without sticking to the inside of the container.

On the other hand, Super Glue is different and tends to become dry insides its container more often than white glue. That is considering super mucilage is made from a chemic component called cyanoacrylate which reacts quickly with wet or water vapor in the air and forms extremely strong bonds with any surface.

How to Ready Glue That's Stale in the Container?
If your gum becomes dry while it'southward within the container, don't be quick to throw it away as in that location might be some hope of salvaging it and getting it soft once again.
Poke a Hole in the Cap

In that case, you can easily fix the issue by breaking through that thin hard layer. You lot can do that by poking a hole on the cap of the container using a pointed tool such as a pivot or a screwdriver.
Heat with Water
If all of the glue is dried inside the container, you will need to expose it to heat to make it soft.
The best way to practice that is to cascade boiled water into a wide container and then identify the glue container in the water until it'south completely submerged.
Exit the gum container to soak in the water for 10 to xv minutes before taking information technology out. Wait until the container is absurd to touch and press on it firmly to squeeze the softened glue out. If the glue has not softened the first fourth dimension yous heat information technology, exist patient and give it a few more tries.
Use a Paint Thinner
If heating the glue with water does not soften it enough, y'all tin can try calculation a few drops of a pigment thinner to the glue to make it runnier. However, keep in heed that using also much of the paint thinner might cause the adhesive properties of the glue to weaken so it will become less glutinous.
Tin can Yous Brand Dry Glue Pasty Once more?
If the mucilage has lost all of its moisture when information technology dried information technology will be nearly impossible to make information technology viscid once more. You might be able to soften the glue or even get information technology to a liquid form past exposing it to heat, but the adhesive backdrop of the glue volition be too weak to class bonds with any surface.
How to Prevent Glue from Drying in the Container?

If you've lost the cap of the glue, you can try to cover the elevation with tape or stick whatsoever minor difficult object in the hole to prevent air from entering the mucilage container.
You as well need to brand certain the gum is stored properly. It's recommended to put the gum container in a sealable bag (a zippo-lock bag) then shop it in a cool dry out place. For added protection, put a small packet of silica gel where y'all're storing the glue container to help trap and retain moisture.
How to Soften Mucilage That's Dried on a Surface?
To soften the glue that'southward stale on a surface, yous can press a fabric that has been soaked in hot water with soap on the surface for about 10 minutes. If the hot water does not penetrate the gum, you can utilize olive oil, vinegar, acetone, rubbing alcohol, or lemon juice instead.
