For Mold problems:
1. Repair any leaks. Moisture breeds mold.
2. Dehumidify the room. Place a dehumidifier in rooms that contain 55 percent humidity or more.
3. Protect yourself. Wear plastic gloves and a medical-grade mask to protect your lungs.
4. Seal off the room. Block doors and windows before you begin cleaning a room. Use plastic sheeting and painter's tape to seal duct work and other openings, too. This prevents the transfer of mold into other rooms.
5. Use an exhaust fan. This helps pull the air out of the room.
6. Use an air purifier while working. This helps protect you from inhaling too many of the particles.
7. Dust the rooms. Mold spores attach to dust and other airborne particles and use them to travel around.
8. Clean the moldy areas. Use a spray bottle to moisten the areas and keep the mold particles from becoming airborne while cleaning.
9. Disinfect the area. Use a commercial disinfecting spray to spray the mold spots. This helps to kill any spores left behind, even if you can't see them.
10. Dry the area with an old towel.
11. Seal up all sponges and other cleaning supplies. Place anything you used that touched a mold spot in a zip top bag, seal it, and throw it away. Don't carry the bags through your apartment; this could release lingering mold spores from the bag. Instead, throw them out the window, and then dispose of them in a trash can.
