Caulk Savers are these thin orange doohickeys that you insert into opened caulk tubes to plug them up. In addition to the plugging-action, the long stem of a Caulk Saver creates a channel in a caulk tube, preventing the caulk from drying up and clogging the neck of the tube.
The Caulk Saver’s dual-action of sealing a caulk tube to outside air and preventing tough clogs from the inside should help keep your opened tubes fresh and ready to use.
We’re actually in the later stages of a 12-week test of these Caulk Savers, so keep an eye out for our full review. For a little over $1 each, a single Caulk Saver costs a lot less than having to run out and buy a whole new tube of caulk.
