What is the correct method for removing grease spots on fabrics?

The correct method for removing grease spots on fabrics is to apply a volatile dry solvent. This approach is effective because volatile dry solvents are designed to encapsulate and dissolve grease and oil-based stains without adding moisture to the fabric. By using a solvent, you prevent the grease from being set deeper into the fabric, which can happen if excess moisture is applied, as that can spread the stain or lead to water marks. Additionally, solvents evaporate quickly, which minimizes the chances of introducing additional moisture that could affect the fabric.

On the other hand, the method of blotting immediately is useful for many types of stains, particularly liquids, but may not be as effective for grease, as it could just smear the stain rather than fully remove it. Washing in hot water might seem like a practical idea, but it can set grease stains, making them more difficult to remove. Using a dry clean method could be a viable option for some fabrics, but it's typically less effective at dealing with grease stains unless specifically paired with solvent treatments. Therefore, applying a volatile dry solvent is the most targeted and effective approach for grease removal on fabric surfaces.
