The inside of the dryer usually remains relatively clean since only freshly laundered clothes are put inside. However, crayons and pens that accidentally end up in the dryer can leave stains on the drum. Even without such stains, it is essential to remove lint periodically. To properly clean a dryer, you need a sponge, all-purpose cleaner, a toothbrush, WD-40 spray, rubbing alcohol and a dryer vent brush.
Unplug the dryer
For your safety, unplug the dryer before cleaning it.
Wash the outside of the dryer
Use a sponge and all-purpose cleaner to clean the outside of the unit. Clean around the controls using a toothbrush to reach difficult areas.
Clean the drum
Spray the all-purpose cleaner on the sponge. Wipe down the inside of the unit. If there are marks inside, use the abrasive side of the sponge to scrub the drum. Use the WD-40 spray to dissolve melted crayon. If ink has stained the drum, use rubbing alcohol.
Clean the lint trap
While the lint trap should be emptied after every load, a vacuum can be used to clean any lint that has accumulated around the trap. Remove the vent duct from the back of the machine, and check for lint buildup. Remove any lint using the dyer vent brush. Reattach the vent, and plug in the machine. If you have used solvents inside the drum, leave the door open to allow them to evaporate before use.
