I don't know what's inside it and to find out would destroy the fuse.

Also, what if it appears to work? Could it not then let through far
more than the rated current?

Hardly, the resistance of the wire inside it will be a fraction of an
ohm, the resistance of the 'damp sand' (or whatever) will be tens if
not hundreds of ohms. Water isn't a very good conductor, distilled
water is almost an insulator, it's mostly down to dissolved impurities
that water conducts at all.

Would detergent make a difference when it has been in the washing
machine - or indeed heat?

(Again, not a serious question as I shall use a new fuse from the
packet when the time comes.)
