More on fighting clogs

Now that you have this handy list to help you, it will make the choice much easier. Or it won’t?

When solving (or dissolving) a clogged toilet problem, you need to use some sort of strategy. Let’s say a smart approach. Normally the first thing to do is try flushing the toilet or using a plunger.

The next step is usually some DIY mixtures which can be helpful and effective.

However, if the thing that caused the block is some kind of object, then using a liquid, powder, gel or whatsoever won’t be of help.

This is very important to note, as you cannot expect any of these products to disintegrate a toy, a comb or a small bottle that ended up in the toilet accidentally.

These formulas are designed to fight clogs that are of organic origin.

Toilet Clogged with Toilet Paper

For physical obstacles, you need a wire coat hanger, a drain snake or a wet/dry cleaner to pull the object out. If the problem is beyond the powers of some methods you can apply on your own, then calling a plumber is the option.

When choosing the right product for the problem, carefully read the labels. See which are ingredients and read the instruction on how to use it.

Some of them work instantly while the others need to be left overnight. Some of the products you can use on daily, while there are those which are applied on monthly basis.

All in all, only when you know what was the cause of the problem you can get down to fixing it. All of these products are indeed great, and if you use them as written, they will give their maximum.

How to Unclog a Toilet without a Plunger or Snake
