Turn washer to highest level and hottest temperature. With nothing in the drum but water, put two cups of bleach in and let the washer lid sit open allowing the hot water and bleach clean the drum. After letting that mixture sit for awhile close the lid and let the cycle go all the way through to the end.

Once the cycle is complete, start it over again at the highest level and hottest temperature and add the two cups of white vinegar into the water. Again let that sit for awhile with the lid open. After letting it sit, close the lid and allow for the cycle to finish.

If you can, remove the fabric softener dispenser and bleach dispenser from the machine and scrub them. Remove the agitator from the drum and clean the inside of that too. Once all that is finished, re-do the two steps of bleach and vinegar again. Your washer should be completely clean after that.

My suggestion is that you DO NOT use fabric softener in your loads. Instead replace it with a cup of white vinegar, or nothing at all.

When you go to dry your laundry DO NOT use dryer sheets because they are a fire hazard and also produce a film in your dryer allowing lint to adhere to the inside increasing your chances of having a fire.

Also I suggest that you have a chimney sweep come and clean out your lint trap that goes from the dryer to the outside of the house. This improves the dryers ability to dry your laundry and decrease the chance of a fire.

By doing all these things your laundry will come out cleaner and smell better than you ever imagined.
