The Mistakes you (still) make when using the dishwasher

Although it is always said that what you do yourself is better in every way, experts indicate that hand washing is less ecological and economical than doing it in the dishwasher. Josep Freixa, delegate of the Winterhalter dishwashing and industrial washing systems in Catalonia, Aragon, Andorra and the Balearic Islands, is clear: “When we wash them by hand, we spend much more water almost without realizing it and we do not achieve such effective hygiene”. Cristina Cusí, Professor of Food & Beverage at the Barcelona ESHOB high school of hospitality, adds that the water in the machine reaches temperatures higher than those supported by the hand, favoring total disinfection.

They convince us. We are going to buy it and we find that there are different types, sizes, and budgets in the market.   Do we know which one to choose? Do we buy it expensive or a better one cheap? And once we have it at home, do we know how to get the most out of it? Do we place cutlery and pots well? Should we always use salt? How do we clean it?

If you continue reading you will discover curiosities such as why we have left marks of drops in the glasses and the real function of the rinse aid, which serves for something more than to make the dishes shine. Above all, you will know the 10 basic mistakes to avoid when washing the dishes in the dishwasher.

1. Pre-wash the dishes with water before putting them in the dishwasher

“It makes no sense to remove food scraps from the dishes by putting it under the jet before entering the dishwasher because we will spend twice as much water, ” explains Cristina Cusí, professor at the ESHOB school in Barcelona. But it is clear that it is essential that the dishes enter the machine as clean as possible, “because the dishwasher can with stains, and with grease, but it is not a waste shredder if they enter, they accumulate, we will have a bad result and they can block it, ”says Josep Freixa, an expert in industrial dishwashers and a representative of the high-end German brand, Winterhalter.

Therefore, we must remove the visible remains with a fork or by hand following the maxim that “the less dirt there is on the plates, the better they will be”. Cusí recommends the pastry tongues (rubber spatulas) to scratch the very difficult fat and drags the crap out of dishes and utensils.

2. Do not adapt to my needs the type of dishwasher and the number of washes

In the domestic market, there are various ranges, categories, and sizes but the key is in its use. “What consumes less to put a large dishwasher full a week or a small one every day with little load?” Freixa asks. It sounds logical to think that the first option is the good one, and we are right. The expert believes that a couple without children may find it cheaper to place the dishes in the dishwasher and when it is full (without overflowing, of course), start it up. “Obviously we have to use common sense and not spend many days with dirty dishes inside the device,” he says and recalls the importance of placing them clean of debris.

What if we don’t have enough dishes? “It is more important to buy more, because there are very good prices, than use the dishwasher more times than necessary.” The best advice is that everyone adapts the dishwashing to their circumstances and needs, taking into account that it will always be more sustainable, efficient and economical to fill it within the established limits than to use it half empty. 

3. Save on the purchase of a dishwasher, because cheap is expensive

In his professional practice, Josep Freixa has verified that the purchase of a quality dishwasher always comes to mind. On the one hand, a good device lasts longer and consumes less energy; and on the other, it also cleans more effectively. “If we could see a dishwasher with glass walls, we would observe how water reaches all corners much better in a good device of a recognized brand than in a low quality one,” he says. Because everyone can see when a dish is dirty, but it is impossible to check hygiene at a glance because bacteria are invisible to the eye. “You can save 500 euros on the purchase, but you will get a worse result and more spending on electricity,” says the expert. source:
