Leftover food is one of the top causes of drain blockages in the kitchen sink. However, this can be avoided with simple drain maintenance. If you do not have a garbage disposal installed, avoid throwing any residual food into the sink. Instead, scrape as much as you possibly can off into the trash can before washing the plate or any other dish off in the sink. You can also make sure to have a drain cover that will allow water to run through, but will catch food particles. Make sure to empty the drain cover out once you have finished washing he dishes.
The second tip for good drain maintenance is to avoid pouring any liquids down the drain that have the potential to solidify. These types of liquids include any type of oils or grease. Instead, use a paper towel to soak up any oil or grease and then dispose of them in the trash can before proceeding to rinse your dishes off as you normally would. This also ensures that you pick up any food particles as well contained inside the liquid to prevent it from going down your drain and clogging it.
A hot water flush should be used once a week for proper drain maintenance. A hot water flush is done by boiling a pot of hot water on the stovetop and then pouring the hot water directly into the hole for the drain. Cold water should be run for a minute or two after putting the hot water into the drain. Repeat the process of each drain in the house twice. The hot water flush helps to break up grease and free food or dirt particles that may be clogging the drain. Performing the flush once a week will keep the dirt, food, and grease from building up inside the drain and will also keep the drain from smelling bad.
Another tip for drain maintenance is the use of a baking soda and vinegar treatment.
When you are done using the drains in your home for the evening, pour one half cup of baking soda into the drain followed by one half cup of vinegar. Put the plunger into the hole for the drain and allow the mixture to sit in the drain overnight. In the morning, perform the hot water flush detailed above. This treatment will break up any dirt, grease and food residue and will leave your drains smelling great.
Last, but not least, use a plunger. If you are new to drain maintenance and your sinks are already clogged, use a plunger in your bathroom or kitchen sink and then keep up with the maintenance. To plunge your bathroom or kitchen sink properly, insert the plug into the sink to keep water in. Fill the sink with three to four inches of water and then remove the stopper. Grab the plunger and use it three to four times. Make sure to rinse the sink out really well to avoid the dirt or residue going back into the drain.
