I use the same cloth that I wash up dishes with to wipe the table/table mats and the kitchen counter-tops.
I change the cloth regularly and microwave it most evenings too.
I always thought this was normal (after all the only surfaces I wipe with it are 'eating' ones), but a friend came round the other day and was shocked.
Do you have a separate table/counter-tops cloth to the dishcloth? AIBU for not doing that?!
