Even if there are no stains to remove, you should clean the inside of the dryer about once a month to prevent odors and debris from accumulating. Use a cloth dampened in warm soapy water to clean the drum and dry it with another clean cloth. If you clean the inside of the dryer with anything other than soap and water, take several hours to use it again. Leave the dryer door open and allow any fumes or debris to dissipate before reheating it.
And prevent fires in other parts of your home by learning how to put out a grease fire, how to clean the oven, and how to clean the stove. According to the Fire Administration, clothes dryers cause about 2,900 home fires each year, and about a third of them are due to a lack of dryer cleaning. Yes, you need to know how to clean a dryer vent, but your education starts with learning how to clean dryer lint. If the dryer vent vent outside your house is located higher than the dryer, you may want to clean the duct from there.
