How to remove dishwasher smells


What causes bad smells in the dishwasher?


It's important to consider why your dishwasher smells before starting to clean it as this can prevent more smells in the future.

One of the most common reasons for dishwasher smells is standing water which can cause mould to grow inside. This can happen if the dishwasher is left closed for a significant period of time leaving water to stagnate inside. You can prevent this by ensuring that the dishwasher is opened regularly and aired out.


Another common reason is due to the accumulation of food scraps and dirt in the interior which can lead to the growth of mould and bacteria. Fortunately this can be easily removed through regular cleaning, as well as a deep clean every 6 months.


Clean the filter


The filter is a key component of a dishwasher and prevents food items from clogging the drain. Over time, the build up of these food items and liquids can cause foul smells.


Remove the drain from the  dishwasher (found on the floor) and wash with hot soapy water. Use a soft brush to scrub in smaller spaces and remove all dirt.

Check the drain for signs of build up and wipe using hot water and a sponge. If the drains smells foul then pour spray white vinegar inside and leave to soak for 5 minutes before rinsing with hot water. White vinegar is a natural way to disinfect and clean your dishwasher and remove odours without using chemicals.


Once clean, reinsert the filter ensuring that it locks into place.


Wipe the interior


Dirt and food grime can slowly build up on the inside of the dishwasher and cause unpleasant odours. Before tackling the walls, gently remove the upper and lower spray arms for a deep clean. Use hot water and a sponge to remove food particles. If necessary, use a cotton swab to reach inside smaller holes. Run water through the holes to make sure that all the holes are clear and unblocked.


Remove upper and lower racks and run them under hot water. Spray with white vinegar and leave to soak for 5 minutes before scrubbing with a soft brush. Remove white vinegar traces using a sponge.


Spray white vinegar into the inside of the dishwasher covering all the walls from top to bottom. Leave to sit for five minutes before wiping with a soft damp cloth to remove any remaining residue.


Place the spray arms and racks back into place, ensuring that they lock into place.


Run a cycle


Place a bowl with white vinegar onto the top rack of the dishwasher and run a short cycle. This will rinse the inside and remove any remaining scents.


Top tip: Run a short cycle with vinegar occasionally for a quick clean in between deep cleans

Start by wiping the wood with a soft dry cloth to remove any dirt. Lay a soft t-shirt over the water stain and gently iron in circular motions for at least thirty seconds. The heat from the iron will help the moisture from the water spot to evaporate. Repeat the process until the stain has been fully lifted. How to remove water stains from wood with baking soda Baking soda is a natural, cheap and effective way to remove moisture that is trapped in water stains on wood. Mix a tablespoon of baking soda with water until a paste is formed. Apply the paste to the water stain with a soft cloth and rub for a few minutes. Always follow the grain of the wood and avoid applying the paste to areas around the stain. Leave the paste to work for five minutes and remove using a dry cloth. Apply a little oil or furniture wax to re-seal the affected area. How to remove water stains from wood with vinegar Mix equal parts of white vinegar and olive oil into a bowl and apply the mixture to the stain using a dry cloth. The vinegar will work to lighten the stain while the olive oil will help to restore shine in the wood. Wipe in the direction of the wood grain until the stain has been removed. Finish by wiping the mixture away with a clean cloth.

How to remove blood stains Top tip: always check the manufacturing label for guidance and avoid using warm or hot water as this can set the stain. How to remove fresh blood stains Acting fast when treating blood stains will make the stain easier to remove. Rinse the stain in cold water immediately to try and remove blood from the fibres. If treating a lighter material, use distilled white vinegar to life the stain. Spray the affected area with the vinegar and leave to soak for at least 15 minutes. Use a soft cloth to blot the vinegar away and place the item in the washing machine on a cold cycle. For darker materials, mix a few tablespoons of water with baking soda until a paste is created. Place the paste on the affected area and leave for at least 20 minutes. Scrub the paste mixture away using a soft brush (such as an old toothbrush) and wash on a cool cycle. How to remove dried blood stains Dried blood stains can be tougher to remove and may require more patience and elbow grease. Start by removing any solid deposits by scraping them away with a blunt knife. Soak the item in a bowl of cold water, laundry detergent and a few tablespoons of salt for at least one hour. Salt is an effective way to break down blood stains without using any harmful chemicals. Then, remove excess water from the fabric and apply more detergent to the affected area. Place the item in the washing machine on a cool cycle. If the stain is still visible, repeat the process above and create a thick paste using cornstarch and water. Apply the paste on the blood stain and leave to dry before scrubbing away with a soft brush.

Sleep is one of the most important aspects of our health and one of the biggest factors to getting a good night's sleep is the comfort of a mattress. But how often should you replace your mattress? We've put together some key indicators that show that it's time to replace your bedding. Read our top tips for when it's time to replace a mattress below. At MMCS we have over two decades of experience in cleaning properties across the North East. Our trained staff use environmentally-friendly cleaning materials to make your property sparkle around your schedule. From one-off deep cleans to a regular holiday let changeover service in Northumberland, get in touch to book your service today. Understanding when to replace a mattress Noise Your mattress shouldn't make any loud noises, even if you toss and turn regularly in your sleep. If you start hearing loud sounds such as grinding metal or springs then it could mean that your mattress is not supporting you as well as it could be. As well as keeping you awake throughout the night, the moving springs can create an uneven surface which can later cause body aches and pains. If you notice that your mattress is making noises, it's often a sign that it needs to be replaced. Allergies Dust mites are a common household allergy. The build up of dust can cause allergic reactions such as sneezing, a dry mouth and throat and a runny nose. While regular vacuuming and deep cleaning of the mattress can help to ease this , older mattresses tend to store more dust and could be the root issue for allergy symptoms. If you don't notice any improvement after deep cleaning and vacuuming your mattress, it could be a sign that it needs to be replaced. Aches and pains If you find yourself regularly waking up in pain or stiffness in areas such as your hip, neck, back and shoulders then it could be a sign that your mattress is no longer supporting you. Over time, older mattresses tend to drop and sag in places which reduces support that can impact the alignment of your spine while you sleep.
