Cleaning Products

  • Never mix household cleaners. Never, ever mix bleach with other cleaners or soaps, especially ammonia products. These mixtures can create deadly fumes.
  • Avoid products with the antibacterial Triclosan. Germs can be stubborn and adaptable. The use of Triclosan may create resistant germs. Simple soap and water are just as effective. Find more tips on Cleaning Products from the WA Toxics Coalition.
  • Choose a product with little or no scent and avoid aerosols. Perfumes can irritate people who have sensitive skin or respiratory ailments. Aerosols can send propellants and solvents throughout the air. Pump sprayers or wipe-on liquids are a better choice.
  • Avoid air fresheners and fabric softeners. These products can send particles and perfume chemicals into the air and trigger asthma and skin reactions.
  • See Guide to Safer Products for safer substitutes to potentially hazardous household products.
