I have a Vax 5150 or several years vintage. It doesn't get used very often,
just an occasional bout of carpet cleaning.

The water take-up pipe in the cleaning reservoir has a porous bronze
filter, which also acts as a weight to keep the take-up pipe down at the
bottom of the reservoir.

By a process of trial and error elimination, I've found that the filter is
pretty much clogged up, presumably with a mixture of dust and old dried-in
detergent solution.

Any thoughts as to a suitable means of de-gunking? I've tried three or four
changes of boiling water, switch cleaner (which evaporates almost on touch)
and a quick immersion in cellulose thinners, all of which have only made a
marginal improvement.

Soak in something aggressive like petrol and BLOW the **** BACKwards out
of it.

If that don't work, ditch it.

A standard quick cleaner would be caustic soda and boiling water. You
cant really use HCl here.

If that fails, the most powerful cleaner of all is a long soak in warm
bio washing powder - by long I mean days.

I would try running it through the dish washer, or perhaps the washing
machine, on hot. For the latter, perhaps put it in a sock, closing the
end with a plastic clippy thing, as used to seal half eaten bags of
crisps etc.

Works well with grubby Lego, inside a pillow case :-)

Good soak and backflow, how much "suck" is there in use? You probably
need to match that with the "blow".

You could probably replace it with no fines concrete. The cleaning
solutions are alkaline.
