One such niche is the category of brands that solve unique problems; in this case the “problem” is people who leave drink glasses on furniture without a coaster.
Jasco Furniture White Ring Remover is one of those brands; it is basically a small hand towel inside a jar doused with some sort of secret waxy potion. When you rub the cloth on a tabletop drink ring, it removes it. The product is made by Homax of Bellingham, Wash.; from what I understand the JASCO name has been dropped and it is now the Homax White Ring Remover. Ingredients aren’t listed, though it really smells like wax.
Curious if other folks find it useful.
