This isn't so much a clean-up tip, as an explanation for the tube of toothpaste in your kitchen.
If you burn yourself, and it's still stinging after you've held it under the cold tap for ever, dab some toothpaste (not gel) on it, and that will take the sting out of the burn.
I heard this from my neighbour, who was brought up in damp, grey Bedford, got married at 17, and went off to America, where she started married life by getting painfully sunburnt. Her older and wiser in-laws told her to take her clothes off, and they proceeded to smother her in toothpaste. She thought they were mad while they were doing it - but it worked, and now she tells everyone else.
