Products that contain quaternary, chlorine, pine oil or phenolic can be a disinfectant. They should display an EPA Registration Number on the label and be labeled as a disinfectant. Use the hottest water safe for the fabrics you are laundering. For colorfast or white textiles, add ¾ to 1 cup chlorine bleach in the wash cycle. However if there is a large amount of iron in the water, can cause rust stains to appear on fabrics. For fabrics that cannot be washed with bleach, add 1 cup of pine oil disinfectant such as Pine-Sol or 1 cup of phenolic disinfectant such as Lysol to the wash.
