You may be surprised to know how many common products contain toxic or irritating chemicals that can affect indoor air. For example, freshly dry-cleaned clothing may give off solvent vapors. Air out your freshly dry-cleaned clothes in an unoccupied room. Petroleum solvent-based paints release solvent vapors during use and during brush cleaning. Use water-based paints whenever possible, but make sure they do not contain mercury.
Paint stripping chemicals can contain methylene chloride, which is a suspected cancer-causing agent.
Never store gasoline in the home. Pesticides should only be used when absolutely necessary. Even moth balls give off potentially hazardous substances in small amounts. Pesticides should be stored in the garage or away from inhabited areas. Hire a licensed pesticide applicator if you have a major pest problem.
