I have started to wonder if ppl wash the mop heads after use? I lent my neighbour our mop and was actually embarrassed when I handed it over - it looked far greyer than I realised. I can be quite anxious and now sat wondering if ppl actually rinse it out or even wash mop heads? Or change them after each use? I try to use my ones more than 3 times, even if they look a little grey as I don't like waste, but am I being a filthy ho-bag? Will the neighbour call me slovenly? (Lighthearted).
