Washing hands, there are 2 ways to do this and not get scalded so it amazes me anyone does.
1. If you have a mixer tap then you run the water at the correct temp and wash you hands.
2. If you have a hot & cold tap you pop the plug in and fill the sink with enough water at the right temp to wash your hands.

It really cant be any more complicated.

No-one was talking about washing their hands! A poster referred to scalding his or her hands in the water used for washing dishes. I suggested this could be an issue if the water is at, say, 45°C for six days, but then 65°C when you weren't expecting it. If you put your normal amount of hot and cold in the sink, it'll be too hot.

Out of interest, when you wash your hands in the sink, or under the mixer tap, how do you check the temperature is right before risking scalding your hands? Do you use a thermometer?

I don't use a thermometer no, I use the good old fashioned method of swishing my fingers through the water in the sink or under the running tap (quickly). I've never been burned yet.

My Mrs has a bath at about 1000 degrees I'm sure, that water is normally still too hot for me about 3 hours later.
