How To Remove Stains From Unknown SourcesStains from unknown sources fall into two categories - either they appear seemingly from nowhere, on a garment you use frequently, or they are mystery spots on a vintage item that has stains without clues as to their age & origin.
For the first case, try the following steps (if the stain has set, lubricate it with eucalyptus oil or glycerine overnight first). Then follow with the steps for fruit & vegetable stains.
In the case of mystery spots with no known age or origin, the only option is to eliminate the possible components of the stain by trying a variety of solvents. Use this list in order, blotting and applying as much as the fabric will allow:
- dry cleaning solvent
- detergent (diluted in water)
- borax (diluted in water)
- ammonia (diluted in water)
- an enzyme pre-soak (like Shout, diluted in water)
Note that some fabrics cannot handle some solvents, so always test first in an inconspicuous area.
