What child likes to use a glue bottle when no glue comes out? The answer is no child does.
Here is how we keep our glue bottles working like champs. Everyday to every other day we remove the lids from the bottles and place them in a pan of water. We then bring the water to a boil with the lids in it. Once it comes to a boil we turn off the heat and remove from the burner.
We remove the hot pan from the stove and cover it with a damp cloth so that it keeps steaming. Once the water is cool we make sure that water goes through the opened lid.
I know that this sounds like a lot of work (about 10 minutes) but you will be glad that you do it when it is time to work on a small group project that requires glue. Every thing will run smooth and you won’t be messing with unclogging the bottles.
The bottles in my classroom have been there for 2 years now and are still like new.
