I have had several spray foam cans and I've noticed that after they
are used once and not emptied, the straw in the spray foam can
obviously gets full of spray foam. How do you clean it properly to
have no spray foam in it after use ? I tried tilting the can upside
down to blow air into the straw but that didn't work. Is there a
recommended way to clean that straw ? I checked the can and NOTHING
was provided for that.
Thanks.

It's a single use product, so forget using multible times. What you
have left over does look real when sprayed out in a swirl pile and
staimed dark brown though!!

imho:

I was told for polyurethane expanding foam, and this was re-affirmed
after reading fire blocking foam can, that you leave the straw alone
filled with foam. When you want to use the can again, you snip off an
inch of the straw and then start again. It seems the tip will harden
and protect the rest of the straws contents. Check the the can out,
it might have a different set of instructions.

What I have done is put a steel coat hanger into the straw. When you're
ready for reuse, pull the steel out, the foam will dry around it, and you're
good to go!

Although, I do like the spray in a swirl and stain it brown option!

Now you know why they come in regular size and tiny little 12-oz
cans...
