I remember these; I was always a fan of Phyllis Diller even though, during the era this commercial aired, it wasn't "cool" (mostly to high-toned women)to appreciate self-deprecating females in comedy. Screw 'em.
Actually everything promoted in this commercial turns out to be true. When I lived in Hyde Park NY, the water was so hard that every time I used chlorine bleach you could see the wash water turn yellow as it was added. The solution turned out to be the peroxide bleaches and/or heavy duty water softeners.
