7 Best Washing Machine Cleaners for Odor, Mold and Grease

Your washing machine washes your clothes so does it really need cleaning? Yes it does.

Many people believe that because washing machines are constantly in contact with detergent and water, that they will always be clean. That is not true. In fact these machines are prone to dirt and germs because they are exposed to moisture and have many crevices which often trap and accumulate dirt.

Moisture which doesn’t dry properly causes mildew or mold which could be behind the unpleasant smell coming out of your washing machine.

There are many washing machine cleaners which can be used to clean and care for your washing machine. In this article we look at 7 best washing machine cleaners to help you find an ideal product for your machine.

We recommend Weiman washing machine cleaner because you don’t have to run a washing cycle when you use it.

Benefits of Using the Best Washing Machine Cleaner

To get rid of odors

Low temperature or economy washes help to save money but they create a perfect environment for bacteria to breed. These cause a musty smell in the machine and if left long enough, the same odor is transferred to your laundry.

Proper machine operation

There is a lot going on in a typical wash. There are a host of chemicals in detergent, dirt from dirty clothes and fabric softener.

Residues from all these can get caught in different parts of the machine. When this happens they form a thin film which traps bacteria. These bacteria can then grow and clog the inner mechanisms of the machine so water doesn’t get as hot as it should. Bacteria could also interfere with detergent action so that it is not as strong as it should be.

Products Tackle Specific Problems

Washing machine cleaning products can be pricey. As a cost effective alternative, many people use baking soda and vinegar or bleach.

While these are effective in achieving a deep, general clean and getting rid of odors, they cannot match up to store bought cleaning products.

Apart from a thorough clean, these products allow you to tackle specific individual problems which homemade solutions cannot do.

If you live in a hard water area for instance, you can select a cleaning product which gives a thorough clean but is also specifically formulated to deal with limescale.

If you have many pets and are constantly dealing with pet hair in your machine, you can get a product which cleans but is specifically made to tackle hair in machines.


Most homemade washing machine cleaning solutions are time consuming or require more water.

When using bleach for instance, it is recommended that you leave the bleach in water in the drum for an hour before proceeding with the process. Homemade solutions also require you to run a few cycles for a satisfactory clean.

Store bought cleaners are often packed in convenient forms such as tablets and only need a single cycle for a complete and thorough clean. This saves you time, water and electricity if your multiple cycles are done with hot water.

Weiman Washing Machine Cleaner and Deodorizer

If you can’t afford the time to run a cycle to clean your washing machine, the Weiman spray-and-go formula is best for you.

You only need to spray and go. You don’t even have to wipe. This not only saves you time but also saves you water as well as electricity if you usually clean using hot water. It removes residue and deodorizes to control odors.

Another advantage of a spray cleaner is that you get to reach all problem areas, including the door seal and gasket which often harbors a lot of residue. A wash cycle will not reach these hidden parts.

It is bleach free, has neutral PH and contains no VOCs. It doesn’t matter what kind of machine you have. This spray can be used on front load, top load and high efficiency machines. It is also compatible with all septic systems.

One demerit is that this spray cleaner needs to be used quite frequently in order to enjoy the intended results. While other forms of cleaners are used anywhere between once a month and once every few months, recommended frequency for this one is after the last load of the day.


  • Convenient use – spray and go
  • Saves time and water
  • Reaches all problem areas
  • Can be used on any machine


  • Requires frequent use

Factors to Consider When Buying the Best Washing Machine Cleaner

Your Specific Need

Just about any cleaner you come across is made to meet certain standard needs such as kill germs, get rid of mildew and odors.

With these needs taken care of no matter what you pick, you can then look for a brand which specifically mentions a need which is specific to you.

Limescale and hair are some specifics.

Does it remove limescale?

Limescale is that whitish scaly deposit you notice in your machine after a few months of use. It is a side effect of hard water.

Every time this kind of water passes through your washing machine, deposits are left in the drum, seals, hoses and other parts of the machine.

If you live in a hard water area, it is more likely to be a problem for you. Select a washing machine cleaner which mentions limescale as one of the problems it tackles.

Does it remove hair?

Pet hair in your clothes can be a stubborn problem in washing machines. When mixed with water it forms clumps which can prevent proper draining. If you have several cats for instance, you will need a washing machine cleaner which tackles pet hair.

Form of cleaner

Washing machine cleaners come in different forms. They could be in tablet, powder or liquid form. It is up to you to pick what works best for you.

Tablets are convenient because they are pre-measured quantities. You only need to throw one into the drum and start the machine.

Powders are often packed in pre-measured sachets so you just snip and empty the contents into the drum. Liquids are more soluble than tablets and powders so they work faster.

Method and frequency of use

Each manufacturer indicates a recommended frequency. Some are best for regular monthly maintenance and others provide a deep clean which is necessary every few months.

Multi-purpose products

It doesn’t hurt to have a good quality, effective cleaner which can be used for other cleaning.

Most washing machine cleaners are made for that and that alone. Others like Ecozone washing machine and dishwasher cleaner can be used for both of these purposes.

If you come across a cleaner which can serve another need for which you ordinarily purchase a separate product, it becomes more convenient and probably ends up being cheaper.


If you thought there is no need to wash a washing machine, now you know different. Finding a good cleaning product can be confusing because there are so many to choose from.

Look for a product which meets your individual needs and performs well in terms of the standard expected outcomes of thorough cleaning and odor removal.
