Dry cleaning at home that "Works in Gasoline or Naptha Like Soap Works in Water". Can you imagine that, what a concept. but I would think quite dangerous. The instruction sheet says another thing to remember : When lifting the garments out of the gasoline, lift out slowly, because to lift out quickly you may create a spark of friction.... Maybe this is why this jar of Solvite is almost full. There is no date, but looking at the drawings of the women it probably in the 20's. The jar label is in great shape as you can see by the pictures; the instruction sheet has very little wear. the box however is worn, sides are all together, however there is no top and bottom loose.  This is a great display piece and an interesting conversation piece for your collection.
