My MIL called in for a coffee the other day, sat down to sort out some money she owed me and managed to drop a coin down the side of sofa cushion. She slid her hand down to retrieve it and her hand came out covered in all this black dust!
She said (half jokingly), OMG how often do you clean down there?
After she went I took cushions off sofa and was horrified to find dust, a small plastic toys, loose change and a few screwed up tissues! I've now given it all a good hoover with nozzle and put cushions back on sofa. How does all that muck get under there? I do hoover/clean regularly but don't think about UNDER the sofa cushions. Anyway, all lovely and clean now
