Your Questions: Grease Stains

By Dr. Laundry September 25, 2007

I received this inquiry recently from Robert, who has been dealing with a tough stain!

Q: Can a small amount of Lestoil be added directly to a load of greasy restaurant clothing? I know it is used directly on a stain for pre-washing, but can I add a bit to the wash load when all clothing in the load is greasy? Thanks!

A: The simple answer is yes. You can add Lestoil to washer, but for greasy clothes, it is best to apply products full-strength to the grease. That way it can start dissolving it before it gets into the wash water. Grease and oil don’t mix well together. So adding Lestoil or other grease cutters to wash simply dilutes them and then they must seek out the greasy stains in the wash water. Both very inefficient practices. Hope this helps!
