What Is The Point Of Pre-Washing Dishes?

When one gets a dishwasher I would assume that you don't have to wash by hand anymore. When my friend got hers she used to wash the dishes and everything else by hand and then put them in the dishwasher.





I thought the dishwasher takes care of that for you. What is the point of washing dishes before loading them in the machine?What Is The Point Of Pre-Washing Dishes?
It's a good idea to rinse the big stuff off. And especially red sauces.





But I think the practice of actually washing the dishes before putting them in the dishwasher came from a time in the past where dishwashers really weren't that good at their job and neither were the detergents used in them. You'd often find nothing came out clean so people washed every last bit of food off the plate first.





Now dishwashers are so good at what they do, most modern ones even have built in food disposals. But those who were reprimanded as kids for not washing the dishes before loading the dishwasher... well old habits die hard.What Is The Point Of Pre-Washing Dishes?
Depends on the age of your dishwasher how effectively they can ';scrub'; dried on food.





The one I just got years ago can scrub off nearly anything - even if it sat in the rack for nearly a week before I filled it up enough to make a decent load.





If your friends dishwasher is leaving spots she should check for lime deposits blocking her drain, at most RINSE the dishes and try a little baking soda (1-2 Tablespoons) and vinegar (1/4 to 1/3 cup) in there once a month when you run a load to help reduce the scale.
I rinse my dishes before I put them in the dishwasher. They come out cleaner and the food's not baked on.
You don't really wash them completely. You rinse the dishes off because dishwashers don't always get the caked on food off. So, you have to wash them by hand if you don't rinse them anyway.
it means that you have to rinse off all the loose food stuck to the plate just like you should before you wash up by hand so that it keeps the water you wash in cleaner for longer . you don't want bits of food floating around in the washing up water that your trying to clean the things you eat off.
back in the day when dishwashers were new, they recommended a pre-rinse to loosen up stuff. Not so anymore, just scrape scraps off and load. All she is doing is wasting water.
All the above answers are true. While some modern dishwashers have disposals, a lot are still just standard with a mesh screen to catch food particles and stop them from clogging the drain. One should rinse the dishes to keep the food chunks from hanging out in the dishwasher.
Pre washing them loosens up all of the stuck on food. If u don't have a full load every time u are done eating, then the dishes sit in there and the food gets caked on.
