Solvent Spotting with Isopropyl Alcohol for Ink and Waterproof Cosmetic Stains
Rex says
Rex Sterling, Ph.D. · Head of R&D, Clean Report · Meet Rex
"Dab 70% rubbing alcohol onto a ballpoint pen scribble or waterproof mascara smudge on a white pillowcase using a cotton pad, and the solvent dissolves the ink instantly without spreading the stain."
The science
-
Alcohol dissolves some dyes
Isopropyl alcohol can solubilize some inks and waterproof cosmetic binders, but stain formulas differ.
-
Blotting controls spread
Work from the outside toward the center with an absorbent backing. Flooding can move dissolved color into a wider ring.
-
Test fabric first
Test an unseen seam for dye transfer and follow the care label. Alcohol is flammable; keep it away from heat until fully dry.
Do this instead
Follow product and surface manufacturer instructions. Never mix cleaners.
