We took the horrible orange carpeting up in the 1930's house that we just purchased. There are beautiful hardwood floors underneath. The green padding that was under the carpeting has turned into almost a clay type substance. Some of it comes up easily, bit other parts (especially in heavy traffic areas) has hardened. It is removable, but it is quite difficult. Is there a product out there that will help soften this old padding for easy removal?
