My buisness partner and I are cleaning houses for an extra income. A coustomer called us to clean a room approx. 15x30 room. This room hasn't been cleaned in 20 years. The folks that lived in this house was a heavy cigar smoker.The best thing that we found to clean this room was with a white vinegar and water. Then later after it dries go over it with a murrphys oil for the shine. This oil also gives it a better smell. If anyone was to find something better, I sure would like to know. Thanks to anyone that can help!!!
