And that's where the salt comes in. Table salt can be used to unclog drains, but it's best to use it to prevent clogs from forming in the first place. Just pour a spoonful of this cheap, dirty product overnight and you'll have hardly any clogged drains.

That may sound like a bold statement until you try it. If you have an oily or stained surface, sprinkle on salt and scrub with a soft-bristled brush. The salt will help break up the stain, just as it loosens clogs in drains.

When used alone or combined with baking soda and vinegar, salt breaks down fats, oils, and grease in drains, making them easily run down the drain. In addition to cleaning drains, salt is also very effective at getting rid of drain flies, killing 2 birds with one stone.

While salt will help prevent clogs in all drains, it is best suited for your kitchen sink drain, where fats, oils, and grease are found in large quantities. The shower/bathtub drain is another area where salt will prove effective.

What makes salt pour down the drain at night?

All the drains in your home are designed with a P-trap. A P-trap is a U-shaped curve just below the drain opening, which also looks like an inverted P.

If you want to see a P-trap, look under the kitchen/bathroom sink or on the side of the toilet. However, you cannot see the shower/tub p-trap because it is hidden, but it looks like the one in the sink cabinet.

The P-trap has 2 main functions:

  • Due to its shape, it allows a constant amount of water to be kept there at all times. The water acts as a barrier, preventing sewer gases from going up the drain and using the vent instead. as long as you have onesewer smellin your kitchen or bathroom, one of the P-traps is empty.
  • Catches potential drain clogs, preventing them from clogging the drain further away, where it would be more difficult to unclog.

Any time you have a clogged drain (a drain with standing water or a slow-draining device), the problem is usually with the P-trap. Cleaning the P-trap will cause your device to drain as it should.

When you pour salt down the drain, the salt settles in the P-trap, where it immediately begins to unclog the clog. If it weren't for the P-trap, the salt would just flow down the dedicated drain and into the sewer lines.

Like I said, the main reason to pour salt down your drains and leave it overnight is not to clear clogged drains, but to prevent clogs from occurring. It is always easier to prevent clogs than to deal with one.

To do this, it is enough to pour a tablespoon (or even 2) of common salt down the drain and leave it overnight. For best results, start by running hot water down the drain for about 20-30 seconds.

The hot water will not only melt and remove some of the grease and grease, but it will also replace the cold water in the trap. The hot water in the trap will dissolve the salt better, making it easier for the sludge to break down in the trap.
