Details:
We have a dark residue on our walls from smoking and also from an air-purifier that wasn't working properly...instead of cleaning the air in the area it was placed in our house it produced a dark, slightly sticky-ish residue on all surfaces. We didn't notice it at first &the air-purifier was running for approx. 1 1/2-2mths. Then we noticed that everytime we cleaned our glass tables, TV screen &dusted there was this dark residue on everything no matter how often we cleaned the surfaces. We first thought that it was just from smoking in the house, especially in the area where this air-purifier was which is the main reason that we got &placed this air-purifier there so that it would help w/the smoke smell! But then we started to notice the dark residue was everywhere, all surfaces &the walls &trim/molding so we got rid of the air-purifier immediately. But now we have this residue on the walls and trim work/molding &doors &it is REALLY hard to clean:( Any help or ideas- PLEASE PLEASE!
