You have likely already seen scathing reviews from customers who felt like they had not been given a good enough experience by the company that they decided to work with.
Restaurant customers are among the most vicious of the lot due to the reason that they will often intentionally leave reviews that will make others doubt whether or not your restaurant is even worth going to. The fastest way to get a bad review is to serve food on any kind of unwashed plate, so suffice it to say that this is something that you should focus on before you do anything else in your day to day routine.
One of the main benefits of a pass through dishwasher is that it can very quickly and efficiently get rid of the dirt and grease on your plates, but in spite of the fact that this is the case you should still follow a step by step process in order to ensure that things are done properly. You need to give the plates a good rinse before you put them in the dishwasher so that the particularly stubborn bits of crusted dirt can be gotten rid of.
Dishwashers are machines and they are obviously not going to give any single plate special attention. Rinsing and giving them a quick scrub before adding them to the dishwasher load can be great for you, and it is highly recommended that you do so. This can result in your plates being both hygienic as well as extremely pleasant smelling, something that the vast majority of your customers are definitely going to appreciate because they would know how much work and effort went into it.
