Components of Household Cleaning Products
Abrasives
- Abrasives like pumice, quartz, and nylon meshes help remove dirt through friction.
Acids
- Mild acids, such as vinegar and lemon juice, effectively remove hard-water stains.
- Oxalic acid is a strong rust remover but is highly poisonous, often found in toilet cleaners.
- Hydrochloric and sulfuric acids are used in diluted forms in some cleaning products.
Alkalies
- Alkalies are soluble salts that emulsify dirt and grease for easier cleaning.
- Mild example: Baking soda (sodium bicarbonate, NaHCO3).
- Strong example: Sodium hydroxide (lye or caustic soda) is used in heavy-duty cleaners.
Bleaches
- Chlorine is the most commonly used bleach, while non-chlorine alternatives are emerging due to safety concerns.
Detergents
- Laundry detergents can also serve as household cleaners. Builders enhance their effectiveness by loosening oily dirt.
Sanitizers
