We’ve had an email from Plum:

We’ve got five bottles of mouthwash in the bathroom cupboard – all tried once but never again because they were vile! I was wondering if you had an idea if they could be used for any household cleaning tasks like brown sauce on brass.

Good question. In my experience, most awful tasting mouthwashes are very alcohol-y and alcohol does have antibacterial/antiseptic qualities — does anyone know if it would be enough for cleaning instead of rubbing alcohol?

If you don’t mind having a minty face, I suspect it could be used as a facial toner – a lot of toners have similar amounts of alcohol in them (although alcohol in toners is very drying – the best skin thing I ever did was switching away to alcohol-free cleaning products).

Any other suggestions?
