Cleaning a sink drain with hot water and dish soap

Your kitchen sink is constantly bombarded with food leftovers, grease and oil. That’s why the best way to prevent a clog is to keep your drain free of such build-ups. So, here is how to clean a kitchen sink drain easily:

Time needed: 10 minutes.

  1. Boil water.

    Bring a few cups of water to the boil. The easiest way is to just put on the kettle. Keep in mind that for PVC and plastic pipes, the water should be below boiling temperature to avoid any damages to the piping.

  2. Add dish soap.

    Stir some dish soap into the hot water.

  3. Pour water down the drain.

    Take your hot soapy water and carefully pour it down the drain.

  4. Let it sit.

    Let the water sit for about 5 minutes.

  5. Pour cold water down the drain.

    After 5 minutes have passed, run some cold tap water down the drain to loosen up any leftover build-ups.

  6. Flush again with hot water.

    Bring some more water to the boil and pour it down the drain to completely remove any leftovers.

For increased cleaning power, you can pour a cup of salt in your drain before flushing it with hot water. This will work wonders to get rid of bad drain smells as well.

Deodorising a sink drain with baking soda and vinegar

Nobody wants their kitchen to smell like rubbish or old food. That’s why it’s important to clean and deodorise your sink drain regularly. Luckily, that’s not a hard task at all!

  1. Put in baking soda.
    Pour one cup of baking soda down the drain.
  2. Pour in vinegar.
    Follow the baking soda with two cups of white vinegar. The mixture should begin fizzing up.
  3. Let it sit.
    Let the solution sit and work its magic for 15 minutes.
  4. Rinse with hot water.
    Heat up some water in the kettle and pour it down the drain to rinse it.

And voila! All the nasty odours will have disappeared from your kitchen sink.

Cleaning a garbage disposal with ice, lemon and salt

If you have a garbage disposal, food leftovers may get caught in the blades, resulting in blockages and some nasty smells. So, make sure cleaning the garbage disposal makes it onto your to-do list.

  1. Put in ice cubes.
    Place a few ice cubes down the garbage disposal.
  2. Put in salt.
    Follow the ice cubes up with some coarse salt.
  3. Run cold water.
    Turn on the cold water tap.
  4. Run the garbage disposal.
    While the tap water is running, turn on the grinder until the ice cubes have disappeared.
  5. Rinse with hot water.
    Flush the garbage disposal with some hot water to rinse it.
  6. Peel a lemon.
    Cut up the peel into pieces.
  7. Run the lemon peel through the grinder.
    This will deodorise your garbage disposal and keep it smelling fresh for a while.

How to keep a kitchen sink drain clean

The best way to keep your kitchen sink clean and smelling fresh is to maintain it regularly, so include it on your kitchen cleaning checklist. Flush it with hot water at least once a week.

Avoid putting fat, oil, grease and any food leftovers down the drain to prevent it from clogging. If your dishes and cookware are greasy, wipe them with some paper towels before washing them in the sink.

Try not to use traditional soap in your kitchen sink to avoid the build-up of soap scum.
