Two extra uses for a hairdryer:
1)For warming up those home waxing strips you normally have to rub between your hands (a quick blast will do it- no-one wants nasty burns)
2)For warming the bed before you hop in.
Chamomile tea-not just a revolting soothing bedtime drink- for nappy rash, make a mugful, allow to cool, then soak a strip of muslin cloth in it and put the cloth in the nappy overnight. (I got this tip off MN years ago and tried it on DS2, who had appalling nappy rash. One night's worth nearly cleared it up, two nights' worth and it had gone completely).
Also, fill an empty shampoo/bubble bath bottle with hot water, shove in a few chamomile teabags, shake, leave to infuse, then drain into a clean bottle for a final rinse for blonde hair.
And finally- use a small amount of clear car wax on newly-cleaned glass shower doors. Helps the water run off more quickly and means less cleaning off of limescale marks.
