Busting the “Rinse Before You Wash” Myth

Here at Finish we know that old habits die hard, and rinsing plates before you put them in your dishwasher can be something that may have been ingrained in you for a long time. However, it’s important to remember that your dishwasher can handle a lot more than you think.

Myth: Rinsing plates off before putting them in the dishwasher means they will end up cleaner.

Busted: For some of us this just feels more productive but in reality rinsing plates before you stack them is actually less efficient when it comes to water saving. After scrapping all food particles from plates and dishes before stacking them; the dishwashers can clean using high temperatures to ensure your plates will be hygienically clean.

If your plates are coming out streaky or have residues on them, it may mean that your machine is in need of Finish Rinse Aid, which has five power actions to help with rinsing away, film protection and fighting spots for a brilliant shine.

Myth: If you don’t pre-rinse the dishes, they can’t go straight from the table to the dishwasher.

Busted: Your dishes can go straight from table to dishwasher - provided all leftover food particles have been scraped off. It is important to remove all food particles off plates before stacking them in the dishwasher to help in preventing food debris clogging up the dishwasher filter and spray arms. Extra care to scrape off as much of the stuck on residue as possible should be taken with “sticky” foods such as pasta and rice, as well as leafy foods such as salad leaves, as they can get into places that aren’t visible.

However, if you aren’t going to be running the dishwasher straight away you may find that the left over food residue on plates after scraping can cause your dishwasher to smell. We suggest that you should clean your dishwasher monthly with Finish Dishwasher Cleaner to clear grease build up from hidden parts like filter pipes and spray arms and neutralise dishwasher odours.[1]

Myth: My parents had to pre-rinse dishes before they went in the dishwasher.

Busted: Dishwashers have come such a long way since your parents were younger and modern dishwashers are fully equipped to handle the large amount of dirty items you may have. In previous decades, dishes had to be pre-rinsed to ensure they were clean but with the advanced technology that goes into appliances, they are more efficient than ever.

So, now that you’ve read why you shouldn’t rinse before you wash, why not give it a go?

Dishwashers not only reduce your electricity and water bills [2], but they can also be much better in terms of water efficiency and the environment [3]. By rinsing plates before putting them in your machine you are effectively undoing all of the hard work that the dishwasher is supposed to do[1].

Lifelong habits are hard to break, but when they are increasing your bills and wasting time, a change will benefit you and your bank balance in the long run. Pre-rinsing is a thing of the past so scrape, don’t rinse. Leave all the dirty dishes to Finish Powerball Tablets – it can tackle even the hardest to remove, stuck on foods.
