Study Notes
Stain Types and Characteristics
- Protein-based stains (e.g., blood, sweat, grass) contain globular proteins that coagulate when exposed to heat or chemicals, making them difficult to remove
- Tannin-based stains (e.g., coffee, wine, ink) contain chromogens that can bind to fabric, causing discoloration
- Oil-based stains (e.g., grease, oil, makeup) consist of lipids that can penetrate fabric and resist water-based cleaning
- Oxidizable stains (e.g., fruit, rust) contain enzymes that can break down and cause color changes
Stain Removal Techniques
- Pre-treatment: applying a stain remover or laundry detergent directly to the stain before washing can increase removal chances
- Enzyme-based stain removers: effective for protein-based stains, as they break down proteins into smaller peptides
- Solvent-based stain removers: effective for oil-based stains, as they dissolve and remove lipids
- Oxidizing agents: effective for oxidizable stains, as they break down chromogens and restore original fabric color
- Soaking: submerging fabric in cold water or a stain remover solution can help loosen and remove stains
Laundry Practices for Stain Removal
- Act quickly: the sooner a stain is treated, the higher the chances of removal
- Blot, don't rub: gentle blotting can help remove stains, while rubbing can push them deeper into fabric
- Avoid heat: heat can set stains, making them more difficult to remove
- Check care labels: some fabrics may require special cleaning or stain removal procedures
- Launder in cold water: hot water can set stains or cause dye bleeding, while cold water can help preserve fabric color and integrity
