Today I had a rubber roof installed on my back porch. At the top of the steps there is one glob of tar or roof cement. It is on the top concrete step where I will probably step in it when the sun heats it up and makes it soft. Also my guide dog often lays there. To remove I have a few ideas wonder if there is a better way. I don't want to scrape and use paint thinner I think that would create a bigger mess. My ideas are to freeze it and use a wire brush attachment in my drill and have the shop vac collecting the stuff. To freeze I thought about dry ice if it is available in a fairly small quantity. Or using a can of air this will freeze if I hold the nozzle very close or last resort pile ice cubes. Any ideas? Lenny http://www.geocities.com/lenny_mchugh/
