  • Do not use any other kind of detergent. High-Efficiency (HE) detergent is needed if you have a HE washer. Mold thrives in the presence of too much suds left behind by non-HE detergents. For the same reason, only use the prescribed dosage of detergent.
  • After each wash, leave the door open to enable the machine’s moisture to escape. Mold cannot grow in a moist environment, which is what happens if you don’t do this.
  • Remove damp clothing as soon as possible after a washing machine cycle. Additionally, this keeps your garments from smelling musty, which is a bonus.
  • Using your mildew cleaner, clean the door gasket on a regular basis. Make sure to do this at least once a week in order to keep mold at bay.
  • If the location where you keep the washer is humid, use a dehumidifier to keep the air dry. It’s possible that the mold is caused by water or humidity from outside the machine, thus it’s important to address this issue. A dehumidifier should be installed in the room.

Why Should I Clean the Seal?

It’s no surprise that the inside of a washing machine is a breeding habitat for mold because washing machines utilize a lot of water.

This can quickly escalate into a major issue if not addressed on a regular basis. Even though the rubber seal is typically disregarded in cleaning plans, it can become less than hygienic over time and contribute to bad aromas.

Cleaning the inside of the drum and running service cycles are important, but you should also check the seal’s interior, which is difficult to reach.

How often should I clean the rubber seal?

Do a service wash every time! Washing machines should be serviced at least once a month, according to most manufacturers, especially if they get a lot of use or if the clothes they wash are extremely dirty.

In addition to cleaning the seal on a regular basis, keep an eye out for any symptoms of mould growth. In order to avoid mold buildup, you should clean the seal immediately after unloading the machine if you see filth on the seal’s surface while cleaning the machine.

Always inspect the rubber seal folds after washing to make sure no undissolved washing tabs have gotten caught there if you’ve unintentionally washed tissues. Some of the foul odors in a washing machine may be caused by these.

Cleaning the Seal During a Service Wash

Add one cup of bicarbonate of soda to the drum and around the seal before running a standard service wash on the machine. Dishwasher detergent should also have a cup of bleach and a cup of baking soda added.

For those without access to bleach, you can substitute two cups of vinegar with one-quarter cup of baking soda in addition to one-fourth cup of water.

Run the machine a few times when empty and set the temperature to 90 degrees. The importance of this is amplified if you use the machine at lower, more cost-effective temperatures.

You don’t have to run the service wash a predetermined amount of times. To get the greatest results, you may need to run the machine multiple times if it is noticeably dirty or if this is your first time using a service wash.

After each cycle, take a glance inside the drum to check whether the stench persists or if there are any visible black spots on the surface. If so, repeat the cycle. The hard-to-reach areas on the interior of the seal can only be cleaned after the service washes have been thoroughly evaluated.

Using a clean cloth and some washing up liquid, gently clean the seal with the solution.

The interior of the seal is infamous for accumulating grime and bacteria and can obstruct the door drainage holes, so be careful to clean both the inside and underside the seal as well.

If washing up liquid alone isn’t cutting it, consider white vinegar instead, as explained in the following tip.

Cleaning the Seal with White Vinegar

If a service wash did not remove all of the debris from the rubber seal, you can use white vinegar to clean it. You’ll need white vinegar for this method, and we prefer to use cotton wool balls and buds.

Using cotton wool balls (or pads) dampened in white vinegar, scrub or wipe away the mould from the rubber seal.

Allow the white vinegar to settle for only a few minutes before wiping away any particularly persistent mould.

Use a cotton bud to get inside the hard-to-reach areas of the seal. Use a cotton bud dipped in vinegar to clear out the mold and particles that have built up between the seal’s fold.

To thoroughly wipe the entire seal, you’ll probably need a lot of cotton buds, so gather your supplies now.

Make sure to thoroughly clean the interior of the seal to remove any mold or dirt that may have accumulated.

It’s possible that the accumulation is worse at the seal’s bottom, but it doesn’t mean the top is any more hygienic and should be left to its own ways.

Rinse the vinegar and debris from the seal after it has been thoroughly cleaned. Running a hot, empty cycle in the washing machine is the quickest and most convenient way to accomplish this.

Preventing the growth of mold in your Washing machine

If you don’t clean your washing machine on a regular basis, mold will eventually return, no matter how thoroughly you clean it. Additionally, you should take the following additional measures to prevent mold formation, which are outlined below.

  • Make sure to leave the door open for as long as possible after using your washing machine. It will allow the moisture in the machine to escape, preventing mold growth. In order for the washing machine to dry properly, the door must be left unlocked.
  • Another thing you can do to prevent mold formation is to take the garments from the washing machine as soon as possible. Remove the clothing as soon as possible when the cleaning cycle is complete. It will assist to keep your appliance smelling fresh and clean. The fast evaporation of moisture is another benefit.
  • Use only the proper kind of detergent for the right kind of washer. If you have a high-efficiency washing machine, then use high-efficiency detergent to clean your clothes. The use of non-high efficiency detergent on a high-efficiency washer will encourage the formation of mold. As a result, it is imperative that you use the correct type of mold inhibitor.
  • You should avoid using fabric softener when washing your garments in a machine. The rubber seal is susceptible to mold growth when exposed to fabric softeners, therefore stay away from them.
  • Don’t overfill your washing machine’s detergent tank. Using more than the prescribed amount can leave a detergent residue. Mold growth relies heavily on detergent residue.
  • Routinely clean the washing machine as well as the dispenser and gasket. Mold can be eradicated by wiping them down with a towel once a week.
  • You can use a dehumidifier to minimize the humidity. It keeps mold from growing inside your washing machine by removing excess moisture. A dehumidifier can be installed in the laundry area.

Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.
