What to Do With Open, Half Used Caulk Tubes

We all have open tubes of caulk which sit and dry out.  So what is a person to do about it?

Step 1:

Using a flatblade screwdriver, scrape out about last inch of opening.

Step 2:

Using a q-tip, wipe inside clean.

Step 3:

Using a hot glue gun, fill inside with glue and make it slightly overflowing.

Step 4:

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.
