How do you keep a Super Glue tip tube clear so the lid is not always glued on, or it clogs?

Has anyone tried a toothpick? But even they seem too large and will just get stuck as well! I keep it stored up right, but it NEVER FAILS!

Thank you in advance! That is how I got here actually!

  • This is clearly a problem with no obvious solution, because a few years ago, I bought a pack of 8 or 10 small tubes of superglue for £1 - obviously intending that you will dispose of the entire tube after one use. If you can find this deal anywhere, maybe it will save you a lot of trouble. – Lefty Jul 5 at 8:18

I found the following hints for using maintaining the Super™ glue (cyanoacrylate) applicator-tip clear.

  • When opening a new bottle of glue it is important to make a clean cut on the nozzle using a razor or sharp knife. Ragged edges will capture excess glue.
  • After using the glue, tap the bottle down hard on its base. Squeeze the bottle to blow air through the nozzle Clean the nozzle and squeeze the bottle again and you should hear air blowing through the tip.
  • If a build-up of glue does occur, try scraping off the cured glue with your finger nail. If using a razor or knife to scrape off the cured glue, they can cut into the plastic nozzle —— any ragged edges will capture even more glue next time the bottle is used, which will compound the problem.
  • If the tip does get clogged with dried glue, you can heat a pin/needle in a candle flame and poke it into the opening. The heated needle melts away the dried glue like a hot knife through butter. Heated needles can be a challenge to hold —— you'll need to use something to keep from burning yourself.
  • The writers also include a disclaimer with this method due to any possible fire hazard, but they verify that it has worked like a charm from their personal experience.
  • One user compared "Super™" with "Krazy™" and found that the Krazy glue works a little better, the applicator is easier to use, as it doesn’t glue itself closed as easily as the others.

    I find the part with "tap the bottle down hard. Squeeze the bottle to blow air through the nozzle" interesting. So simple, that I did not think of it :) +1 – virolino Jul 5 at 6:09

It can't always be prevented, but it's easy to resolve. You can drill out the clog using a small drill bit (1-2 mm) and a variable-speed drill.

A very simple trick is to wipe excess glue off the outside of the applicator before screwing the lid back on. Use a dry paper towel or scrap of paper or fabric, but be careful not to glue the wipe to your fingers.

Using a wet towel can set the glue very quickly (so you can see excess glue and scrape it off), but if the moisture gets into the applicator, your glue sets there as well and clogges up immediately.

I had several tubes of superglue glued shut by a tiny drop at the very tip. Just wiping the tip off helped a lot, but sometimes wet glue gets into the lid before I wipe it off. Then I wrap a piece of paper towel around a tooth pick and wipe the inside of the lid as well.

Keep the glue stored with the lid facing up.

Thinking out of the box: Don't use Super Glue at all. No matter what you do, when exposed to air it will harden. Instead buy a 2 part epoxy (for a very similar price). Not only is epoxy much stronger, but it will always flow freely because the two parts of the epoxy only harden in contact with each other (not the air).

  • how long does it last (according to your own experience: what's the longest delay did you tried?)? – JinSnow Aug 1 at 14:20
  • @JinSnow Do you mean the delay between application and initial hardening? It's anywhere between 1 minute to 30 minutes depending on which one you get. (The number is written on the packaging) Personally, I use 5 minute epoxy and that works well enough for me. - After application you should let it sit for a few hours before usage, to make sure it's nice and strong. – Benjamin Aug 1 at 15:48
  • No, sorry for my bad english. I mean how long does it last after opening this kind of epoxy syringe? (According to your own experience: what's the longest delay did you tried?) – JinSnow Aug 2 at 7:02

    I've got a 10 year-old epoxy glue tube. I recently used it, it needed some encouragement to get flowing again (one of the components had gunked up in the nozzle, so I drilled that out). – Hobbes Aug 2 at 9:02

    @JinSnow I've kept epoxy tubes in my toolbox for years and never had one clog on me. Of course, I'm careful to wipe the tube of excess before capping it and I always keep the whole thing in a plastic bag. — ¯_(ツ)_/¯ — Works for me. – Benjamin Aug 2 at 13:44

There may be nothing you can do with those cheap multi-packs of glue that are like little toothpaste tubes, but I've found that going for a dedicated sizeable bottle helps. The bigger bottles sometimes have a metal pin molded into the lid that helps keep the nozzle clear. I also find it helps to blow the nozzle clear and then leave the bottle open and upright until any glue on the outside has dried and can be picked off with a fingernail. Storing the bottle upright also seems to help.
