We decided to find out if the dishwasher is a necessity from the point of view of hygiene and savings or is it about the next blade of housewives. And now what we found out.
How it is best to wash the dishes from a hygienic point of view: manually or in a dishwasher?
In Germany, they decided to conduct a test. 6 used bacteria were given to the laboratory of one of the institutes for checking the presence of bacteria.
The result of the examination: on rags that quickly dry, a small number of bacteria were found. On rags, well -twisted after washing, also lived a little bacteria. The situation is bad with rags, which have been dry for a very long time: 1 cm2 accounted for over 1 million bacteria (at a room temperature of 20 g)!
If you do not want to spread bacteria from a rag, then from time to time put it for 2 minutes in a microwave oven. Thus, you will get rid of 99% of bacteria.
Conclusion: If there is such an opportunity, then it is best to wash the dishes in the dishwasher. Even if you have a small family, it is worth buying a machine, in this case, the dishes can be assembled during the day, and in the evening wash all at once.
Held by the University in g. Bonn, the study shows that the dishes washed in the typewriter, even at the smallest temperature and the shortest program, practically does not contain bacteria.
Anyone who wants to be completely confident in the absence of bacteria must wash the dishes in a machine at 60 grams. Only at high temperatures can the remains of milk in the cup be completely removed. In addition, it may happen that at a low temperature, the drain will be clogged with remnants of the fat. High temperature removes the residues of contaminants.
Which is cheaper: wash the dishes manually or in a dishwasher?
Research conducted by the University in g. Bonn shows that 1 entry of an ordinary dishwasher costs 37 cents. The consumption of energy, water, detergent, salt were taken into account. To wash the same number of dishes, you need to spend 66 cents manually. From the point of view of the attitude to the environment, the use of the dishwasher is also more favorable, since less water is consumed.
