Run a load of whites with some bleach... full load that is...Even if it is just some white shirts or tees.. Not chemically soaked clean up rags... The dryer has a burner in there or an electric heat element.I'd hold back on any aerosols or sprays that can go boom...Unplug the drier.. Get in there with a vac.. clean the lint tray and that area well. tilt it to one side, ( just a bit.) Don't knockaround any little devices which can be costly to fix.. Just get the lint out. Make sure the port hose is free from holes ( and )is made of some kind of metal, not that cheesey vinyl springy hose. A clogged hose is not safe, it will release nasty carbonmonoxide into the room over time. Here's one big time thing to remember. As you are cleaning with all of these sovents and cleaners ( the rest of the place ). Try to put a fan it the window. You don't want to overwhelm yourself to a point where you are going to feel sick during your move. Make sure you take a reading off all of the meters ie ( electric /gas/water.) so the utility companies don't try to hit you for the last tennants bills. I know I'm getting carried away here but what the heck. Here's a trick of mine. Before you fill that refrigerator. Shut down all of the power fuses to your apartment to make sure you are not juicing any other tenants stuff... Trust me, it's happened to me.. Mostly at night when everyone is home using all the lights and tv's.. and don't let them know you are checking this. They will think you are a luney toones but better to be smart than cheated.. You can even check to see if the meter is spinning before you have plugged anything in... (everything must be unplugged)...In my apartment the landlord had a refrigerator in his garage outside connected to my juice...sure as heck.. I caught it...he still got the best of me when I left though....So, good luck with your new place and I hope this helps...Mr Clean Erasers, Lysol, Bleach, Murphys oil soap.. Sponges,Rags etc....
