I decided to rip up very old carpet on my stairs only to find a very nasty surprise of very well glued down underlay. I was able to scrape off most of the black under lay but now i am left with a set of black nasty stairs and all the glue. What is the best and quickest way to remove? What type of sander can i use or what type of stripper is the best? I need to do this myself as it is a rented house (don't tell my landlord i'll break that news after i fix it :whistling2: ).
