Tips for Keeping Drain Clean

1. There are different ways to dispose of common clogs

You can follow different ways of disposing of the garbage rather than draining it down the drain. You can store the grease in some container instead of dropping it into the drain. For the kitchen sink and shower drain, you can use covers that prevent hairs and scum to stick into the drain. After washing the dishes in the sink and bathing in the bathroom randomly you can drown hot boil water, which will prevent the drains to choke.

2. Always Rinse kitchen drains with hot water

Things like food oil can stick to the drain. Always pour hot water just after washing utensils containing food oil. Hot water will easily sink down the food oil down the drain.

4. Toss some baking soda into the drain

Baking soda is a great cleaning agent which can dissolve the waste clogged into the drains easily. On regular basis pour baking soda into the drain to protect it from getting clogged.

5. Install strainers in kitchen sinks

Installing strainers into kitchen sinks can be a smart move. Strainers block the waste food from drowning in the drain.

6. Pour a cup of vinegar down the drain

Vinegar is a great acid created from acetic acid & can do wonders if mixed with baking soda to clear clogged drains.

7. Exercise caution with store-bought cleaners

Commercial Cleaners from the stores can also be effective DIY concoctions. But try to prevent it as much as you can because it should be used with precautions and is not safe in nature.
