Expanding foam removal

[s--p--o--n--i--x]

Does anyone know what will remove expanding foam from a confined space?

Where exactly have you put it?

Oo-er, we're not still on with that thread about popes and rats are we?

If not, try:

A sharp spoon on a stick?

[s--p--o--n--i--x]

I ain't put it anywhere. Someone else on the other hand has stuck it somewhere inaccessible...

Oh, err. I don't know what to say. I'm glad they confided in you, anyway, and I very much hope that something can be done about this, erm, unfortunate situation.

I think acetone is a solvent for it - at least that's what my can says to use to clean the injection tube. Acetone is nasty stuff and has nasty fumes though, so take care.

That may take the paint of..

I use the acetone spray as well. It clears the tube fine but the bloody foam aerosol bit rarely cleans properly. The second time I try to use it, it struggles to come out and forget trying to use it a third time, the press down action is totally screwed by then and I find myself having to rip a screwdriver through the top and spoon the contents into the cavity before giving up and dumping the bloody thing in a carrier bag to ooze out it's contents :-)

Sums it up pretty well ;-)

These tins of foam do seem to be one-use items.

Where do you get it in a spray? I have only seen it in bottles.

Screwfix do it. Won't work on foam that is set though, not in my experience anyway.

I believe that acetone only goes for uncured urethane. Possibly Nitromors will do it, but probably the best bet is to mill it out with a drillbit hoovering as you go. Heat will also collapse it, but beware molten drops of the stuff. Like most molten polymers it sticks to skin and burns deeply. Ouch. BTDTGTTS
