While glue is slightly cooled, but still soft, mushroom out the top.   Let glue harden and you have an airtight seal to your caulk tube.  No more waste.

Update, I pulled the hot glue plug out of the above tube of caulk tonight because I needed to seal up an outdoor light. Still is good 2 years later.

Good tip. Better than plugging it with a tapered dowel. As I used to do until I saw this tip! One point though, are there no adverse chemical reactions between the hot glue & the Caulk / sealant, etc?

Not to my knowledge. Beats the old screws I used to use.
