Well I had a shower today and as usual was struggling to wash my back. Afterwards I got dried, used my toe drier which was easier today but then I noticed ¾ of the way twixt my handle and the 'drying' sponge was another 'cleaning' bit. If I had noticed earlier I would have had to take off the 'drying sponge' temporarily then washed my back with the other brushy bit.
Och well, next time, but it did prove easier
