I've never had a problem with 3mm sheet, using a fine blade, maximum
'attack', and maybe running the machine at about half speed. But cutting
some 5mm stuff the metal was softening and clogging the blade, which was
very hard to unclog. Reducing the speed led to a lot of vibration and
snatching.

I couldn't find any Freezit so I tried a can of VCR head cleaner. This
is very volatile stuff and feels really cold if you squirt it on your skin.

I held the nozzle close to the work and just gave a quick blast every so
often. It worked really well. It completely solved the problem. I was
able to cut with the machine on full speed. The stuff cleaned off easily.

I would think that ordinary switch cleaner would work.

Interesting. FYI paraffin is the usual lubrication for cutting or
milling aluminium.

WD40 works very well also

Cut 12mm recently with no fluid.
Bit rough but just about doable with cheap jigsaw.
