Light a candle
One way to get rid of solvent fumes is to light a candle and let it burn in the room for a few hours. The open flame will burn out the flammable substances in the solvent. Candles still pose a potential fire hazard so place the candle on top of a bowl or a saucer of water to catch any dripping, hot wax and keep young children out of the room while the candle is burning.
A bucket of water
If you don’t want to risk a fire by lighting a candle to burn off the fumes, you can simply place a few buckets of water around the room to absorb the solvent vapours. It is not as efficient as a candle, but is a safer option if you’re painting a room finished with or made with wood.
Onions
Cut large onions into quarters and set them out on plates throughout the room. The residual smell of onion will disappear much quicker than the smell of paint would have.
Vinegar
Place bowls of white distilled vinegar around the room to neutralize odours.
Lemon
Place lemon slices in bowls all over the newly painted room for a day or two and throw them out later to remove any unpleasant paint smells.
Ventilation
Open all doors and windows for as long as possible during the day and night. Putting a fan in the room for this period will also hurry along the process of clearing up any lingering, unpleasant paint smells
