Eliminate bad smells from rooms:
Fill a jar with water and add a little vinegar. Leave it in the room uncovered until the smell disappears. This is a perfect idea for newly painted rooms.

In this case, it is advisable to change the water every 12 hours and repeat the procedure for at least three days.
