- Oxygen Bleach
- Sodium perborate, Hydrogen peroxide, works best if used in hot water
- Soil Removal-Laundering
- Detergents-surfactants, builders. Bleaching-chlorine, perborate
- Surfactant Action
- Breaks up water droplets that surround soil particles by lowering the surface tension and allowing water to penetrate, micelles surround soil and suspend it
- Builders

- Soaps
- made from fatty acids and alkali; doesn't perform well in hard water
- Synthetic Detergents
- made from petroleum, natural fats and oils; dominate home laundry market
- Surfactants
- alter properties of water and soil so that dirt can be removed, Surfactant molecule: Hydrophobic Body and Hydrophilic Head
- Synthetic Detergents
- Surfactants, Builders, Surfactant Action, Bleach, Chlorine Bleach, Oxygen Bleach
- Dry Cleaning
- special cleaning solvents that dry quickly. Perchloroethylene (perc), Environmental Concerns-exploring alternatives
- Chlorine Bleach
- stronger of two types, Chlorine-oxidizes colored matter, rarely recommended for colored fabrics: Clorox and Purex
- Bleach
