Last update: 12 May, 2022

Although we may think that our kitchen is free of bacteria after cleaning, in many cases that isn’t the truth. 
It’s not just the sponge in our sink that is full of germs. In addition, there are many other mistakes when washing dishes that we make that cause too much residue and spread germs.
TCharles Gerba is a microbiologist at the University of Arizona. After numerous studies , he has come to the conclusion that 50 to 80% of all diseases caused by contaminated food originate at home.
These pathogens cause 6.5 million cases of gastroenteritis per year.

The most common mistakes we make while washing the dishes

1. Not using the right soap

It’s a very common mistake not to choose the right soap, or to use a lot of product.
By using too much soap, there may be residue that covers the dishes and ends up in the food.

  • All that’s needed is hot water and soap.
  • Read the labels of cleaning products and follow the instructions that indicate the proportion you must dissolve in water.

2. We waste a lot of water

It’s best to put all the utensils to soak in hot water so that the grease is easier to remove and the dishes dry faster.
  • If you have two basins, fill them with hot water and put the plates and cutlery to soak.
  • You can also put them in a soaking basin and then wash and rinse them.

It’s important to turn off the faucet while you wash each dish individually.  You can use a small bowl of water to wash each dish. That way you do not waste a lot of clean water.

3. Use a plastic sponge

The highest levels of contamination in the kitchen can be found in sponges and dishwashers. These are a perfect home for thousands of bacteria like E. coli and Salmonella .
That’s why it’s a good idea to use a sponge with natural fibers. After scrubbing, hang it to dry completely. Also, it is recommended to change it every week.

4. Not washing glasses and knives properly

This is a very common mistake: when washing knives quickly, a quantity of residue remains. However, you should take longer during this task until all traces of food disappear.
Glasses are also difficult: milk bacteria can often be on the sides, even after washing.
So, you have to check them carefully and rinse them very well to prevent bacteria from growing easily.

5. Not washing your hands first

Hands can be a source of contamination of bacteria and viruses.
Before washing dishes or placing them in the dishwasher by hand, it’s important to wash your hands with soap and warm water.

6. Beware of cutting boards

In the case of meat or vegetable cutting boards, it’s recommended to rinse them first.
Then, drain to let the water run off and then disinfect them with a product or a chlorine solution for two minutes.
  • It’s a mistake to wash them with a sponge and soap as we tend to do. That way, they’re not properly cleaned.

7. Washing in a dirty sink

Your kitchen sink could have more germs than your toilet.

  • It is recommended to clean the sink daily with vinegar and baking soda or with vinegar and salt.
  • This way, everything will be disinfected when washing the dishes without accumulating new bacteria.

Remove food before cleaning
  • First, discard all the food particles from the dishes in a garbage bin. You can use a spatula to remove all the remains of food.
  • Then, place all the dishes and cutlery in hot water to remove the residues and clean them.

One mistake we make is not to remove the food particles, so they’re all over the sink.

Tips for optimally washing dishes

  • Use hot water when washing and put on rubber gloves.
  • Leave the utensils that have touched raw meat for last: this way you will avoid cross contamination.
  • Use a clean, dry cloth to dry the dishes and review it at this time.
  • You can use lemon and salt to disinfect the wooden cutting boards.

It is important to consider all of these points in order to prevent diseases caused by the transmission of germs. In addition to taking care of our health, our tableware will look brand new.
