Preserving Open Caulk Tubes

I don't know if this has been asked here before, but does anyone have a method for saving an open tube of caulk? I've tried electrical tape, wing nuts, drywall screws, a bubble of caulk, and lots more that I can't even remember, but none work for very long. Thanks

Ha! tiny condoms for tiny caulks.

I have never seen those before Tom, thanks.
I get a bunch of the stupid squeeze tubes of color match for laminate counters, and they all have a cap on them.
I throw out the caulking and save the caps for my regular caulking tubes.

I have pretty good luck with duck tape, silicone is harder to keep for any length of time but when i can
I buy the one where the entire nossle tip screws off and it makes it easier to clean out a dried plug. Remember
to check the dates on the tubes and dont use out dated tubes.
Shoot, you mean caulk is dated like my beer?!

In my experience, it depends on the caulk. I mostly use Solar Seal and have done nothing to cap them and used partials months later with no problems (without cutting the tip larger.) Same with OSI Quad. The little bit exposed to the air dries and doesn't seem to dry too far down.

Latex is tough to keep around for long unless you cut the tip larger to get the dried caulk out, even with tape or a nail. Same with Vulkem.

Any partials of non-latex caulk that hardens too far down in the tip, I just save for under a door or for other non-visible purposes.

I've actually had pretty good luck using a 4.5 gallon mud bucket with about 1" of water in it. I put the tips into the water and it prevents air from getting to the material and drying it out. Throw a lid on to help prevent the water from evaporating in it and you're good. Some of the cheap caulk will actually "soak up" the water though...if u use the tube after a few days your first few squeezes of the trigger will shoot mainly white water....but I've only had that happen with that DAP crap Alex caulk. None of the Sherwin Williams latex has done that to me yet. Gotta be careful not to have too much water in the bucket when you've got a cardboard type tube too....

For latex caulk & tubes of wood filler with caps I have discovered that soaking a tiny bit of rag with water then taping or shrink wrapping that to the tip keeps the caulk good for far longer than any other method. In the case of a tube with a cap just stick a little wad of wet rag into the tip of the cap & screw on tight. Still looking for a good solution for storing silicones. Thrown out way too many tubes of Geocel & worst of all nearly full 5200 even though those comes with a removable & cleanable tip. Often end up cutting a dried tube in from the back & applying the caulk with a putty knife. I save the dried tip tubes for jobs where putty knife applications are warranted. Pretty pitiful...

No, a buddy of mine came up with it, so yes a bit of a vested interest, but it doesn’t change the fact that it works. He got the idea from his uncle who used an old Wax toilet ring, but he found that it would melt out in hi heat, and who wants to keep an old toilet ring in their truck, so he came up with some mixture that wouldn’t do that. Again, I keep tubes in the truck in the middle of summer, and have never had an issue.
