Brick floors with gum marks and stains -how are they cleaned and restored?


I would try a high pressure hot water tool with vac pickup or a steam generator. The heat should release the gum and the pressure force it out of the pores. The stains are generally blackened soils held by the gum or film it left when the bulk was removed.
