What foam gun?

[23vc]

Yeah left mine for months for sure, probably not years tho.

cartridge cleaner (probably some wd40 generic stuff).

It is normally acetone.

I'll be using it regularly For new door frames tbh.
Plus any other holes I can find.

But again the end of the nozzle where it exits is exposed and will expand/harden?

That was my point sorry.

I premed it had to be flushed out after each use.
Or I was going to cap off/tape the end so it's not exposed.

Thanks for the advice.

You can spray some of the acetone cleaner on the end of the nozzle to clean it.

This may not be needed, if you scrape off the foam when you next use it.

You don’t need to ‘flush’ it

With the gun I linked, I just scrape off anything around the nozzle, and sometimes give it a quick rub across the end with sandpaper or rub it on a brick. I just leave the can on. Max length of time is easily 4-5 months.
