The oily gunk that is commonly found attached to the dishwasher filter or the sink's drain filter is often a combination of food residue, fats, oils, and grease (FOG). When you wash dishes with a washing-up liquid, some of the grease and oil can still cling to the plates, glasses, and cutlery. Over time, these residues accumulate and can end up in the dishwasher filter or the sink's drain filter.
Dishwashing detergents are designed to break down and emulsify grease and oil, making them easier to remove during the washing process. However, some grease particles can be particularly stubborn and might not be fully dissolved or removed by the detergent, especially when washed with cold water.
To deal with the oily gunk and prevent it from clogging your dishwasher or sink, you can take a few additional steps:
Scrape excess food: Before placing dishes in the dishwasher or washing them in the sink, it's a good idea to scrape off excess food residue to minimize the amount of grease and oil that enters the drain.
Hot water rinse: Instead of using just cold water, try rinsing the dishes with hot water. Hot water is more effective at dissolving grease and oil residues.
Soak in hot, soapy water: For particularly greasy or oily dishes, consider soaking them in hot, soapy water for a few minutes before washing. This can help loosen the grease, making it easier to remove during washing.
Use vinegar or baking soda: You can try adding vinegar or baking soda to the wash cycle. Both of these substances can help break down grease and remove odors.
Regular cleaning: Clean the dishwasher filter and the sink's drain filter regularly to prevent a buildup of gunk. Removing and cleaning the filters periodically can help maintain the efficiency of your dishwasher or sink.
Proper loading: Avoid overcrowding the dishwasher, as this can lead to inadequate washing and rinsing, leaving behind more grease and food residue.
Remember that while dishwashing detergents are formulated to handle grease and oil effectively, some persistent residues may require a bit of extra effort and the use of hotter water or additional cleaning agents.
