Hi All,

A little while ago I was given a batch of pretty sound carpet tiles
that I thought might be good in the hall, spare / work room in the
interim (so probably another 10 years then) ;-)

I asked here about giving them a clean up any one of the replies was
'give em a good scrubbing in the bath' and that's what I've just done
(to 20 of them anyway).

A pressure washer works well too.
