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.


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