For moisture and smell of vomit
If your child, dog or cat has vomited, I have a good tip for removing the gift.
Take the coffee grounds out of the filter and sprinkle it over the vomit. The acrid odor is immediately alleviated, the moisture is bound.
Wait a few minutes, then you can without disgust - helps nothing - eliminate the coffee with the dustpan and the hand brush. Now sprinkle on a sachet of baking powder and after a while suck away the rest.
Of course, this only works if you do not have a modern coffee machine with the capsules!
