protectME is primarily intended to repel liquid stains. It will certainly help cleaning oily stains (chocolate, tomato sauce, sunscreen etc) and dirt marks but we can’t guarantee that there will be no marks left. This is especially true when force is applied onto the fabric, i.e. fingers smudging chocolate all over your new couch. Please always use a light dabbing motion when trying to remove liquids from protected fabrics, trying to absorb the liquid or stains into a cloth, rather than scrubbing with force.
