Think of them as a less pleaseant form of those Dettol multi surface wipes you can buy in any supermarket.

To be honest Geoff because they come in a pack that is about 3" thick, the top ones tend to be a bit too dry and the bottom ones are absolutely swimming. The only way I've found to kinda counteract this is as you use them is to store the pack the other way up every day (works provided you remember to clip the pack firmly closed when you turn them upside down....!)

I laugh in the face of danger. Then I hide 'til it goes away.
