When it comes to washing machines, front loaders are definitely the latest trend. These high-tech machines are highly efficient and easier to load and unload — not to mention more attractive than their older counterparts. One of the only drawbacks to a front-loading washer (or high-efficiency top loader) is the fact that they must be cleaned periodically. This cleaning is necessary to prevent and eliminate odors, since these machines are more prone to mold and mildew (even if you can’t smell it!). Lucky for all of us, these cleanings are very easy to do.
