Glamorene Rug Cleaner
Growin up, we had room-size rugs made out of wool that could not get wet. Before holiday season, parents would have the rugs picked up and dry cleaned. I remember they used to spot clean the rugs with this suff called Glamorene. Came in a jar and looked like wet sawdust. You sprinked it down, massaged it into the nap and let it dry. In about 20 mins, you vacuumed it up and carpet was clean. I recall that it really did work well.
