Stain Categories and Removal Methods
Different types of stains require specific cleaning approaches:
- Water-Soluble Stains: Use water alone or water mixed with a mild detergent.
- Oil-Soluble Stains: Require volatile or refined oil solvents.
- Stains Requiring Bleaching: More stubborn stains may need a bleaching agent for effective removal.
General Stain Removal Tips
- For Fresh Stains: Start with water and a small amount of detergent to prevent interference with further removal attempts.
- Absorb Excess Moisture: Use sawdust, talcum powder, paper towels, or fuller’s earth to soak up wet stains.
- Prevent Re-Staining: Mask off lower areas to prevent loosened stains from redepositing. Polyethylene film and plastic tape can help, except on rough surfaces.
Application Techniques
- Use a soft cloth or brush to apply cleaning solutions, working from the outside inward to avoid spreading the stain.
- Multiple applications may be needed for complete removal.
- Older stains may be harder to remove, and cleaning efforts might alter the stone’s appearance by removing atmospheric dirt.
