When I came home tonight, there was a strange odor in our house. It smelled like nail polish remover. Nobody in our house had nail polish or remover out, or anything that smells like it. It seems to be the strongest by our washer and dryer. The living room and kitchen also smell. It does not smell in the basement, bedrooms, bathroom, or upstairs. Does anyone have any idea of what it could be? I have googled it and can't find any information about what it could be. Could gas smell like that at all? Please help. Thanks.
