Remove hot glue with DNA!

Learned that a few years ago when was gluing what amounted to flying butress supports to extremely thin bowl from board projects. I had to be really cautious when removing the glue. I used dna to help break the bond and a fishing line garrot to saw through it

It works with removing double stick tape.

works the other way too!

I recently bought an industrial grade hot glue gun and a wide variety of hot glues. I can heat the sticks that need it to over 400 degrees. So far I have found that you can remove DNA with hot glue too. OUCH!

Sticking pieces glued together with hot melt in the freezer will allow the glue to pop right off as well. No chemicals needed@

Mineral spirits will work almost as well as alcohol.

Probably any alcohol would work. The first video used IPA(isoprppyl alcohol), not DNA, which is denatured ethyl alcohol.

Works with any alcohol?

Why don't you try it with a good single-malt and report back?

Pretty Scary....

I have never had much faith in hot glue. It must be stronger/better than I give it credit for, but if alcohol will turn it loose this quickly and easily I would not want stake my life on it.

I use it to stick things together temporarily and not much else.

Barry -- Hot melt glue can form a very strong and durable bond (depending on the type of glue, the materials involved, etc.) It is often used commercially for bonds that are intended to be permanent. We used a lot of hot melt glue in the furniture mill where I learned the trade. I think many woodturners would benefit from adding hot melt glue to there arsenal. It's particularly good for attaching a blank to a glue block or instead of a paper glue joint on inside out turning.

The fact the bond can be dissolved by DNA does not mean the bond is weaker than other glues any more than the fact a screw is easier to remove than a nail indicates screws are weaker than nails.

Yes indeed

Bill Howatt

You've got that right. I never thought of the DNA or freezer use to break the bond and always have turned off waste blocks held on with hot-melt glue because they weren't coming off any other way. Wood should be dry though.

The glue should be the "heavy-duty" yellowish stuff not the craft clear sticks.
