If you’ve been stocking up on cleaning products keep these guidelines in mind. Most products can last up to two years. Some signs to look for is, of course, is that they don’t work as well. A powdered product will get lumpy and liquids will separate and get cloudy. Detergents containing bleach and enzymes tend to break down quicker. To preserve your cleaning products store them in a cool, dry place with the packages closed. Dish detergents usually last about 3 months, laundry detergents about 6 months, and bleach about 1 year.
