From Sandra Lister
Slugs
(29 July, p 34) are also good at removing burned-on food. I once left
some potatoes to boil dry. The smell was nasty, so I dumped the pan upside down
in the garden. It remained there for a few weeks and when I decided to have a go
at cleaning it I found that slugs had already done the job. (Note: the pan was
subsequently washed.)
Since then I have often used this method of cleaning. It is particularly good
for ovenproof glassware that has burned-on brown marks.
