Does Caustic Soda Dissolve Hair?

This particular chemical is pretty powerful, and it can dissolve almost anything that is natural – including hair (a paintbrush made with hair will last less than 20 seconds when dipped in caustic soda).

This isn’t all though, as it has been known to dissolve skin and can even remove fingerprints from your hands, as well as burn the skin horribly.

This is why you should always wear gloves and safety goggles when using it, because while it is incredibly effective on drains, it can also cause a lot of damage to your skin and body.

It does, however, practically guarantee that you will have a good drain unblocking experience when you use it, just make sure you check that it can be used with your piping and drain before you buy it as there might be restrictions due to the strength of the product.  You can get a tub of caustic soda at a reasonable deal here

How Do You Unblock a Shower Drain Naturally? 

There are a few ways you can unblock a shower drain naturally – it depends on how severe the clog is and what you have available to you at the time. Here are some of the natural methods that we find work best for you to flick through. 

#1 Boiling Water 

This is often the simplest fix for minor clogs in your drain, and if it is small enough, you should find that this solves everything. All you need to do is fill the kettle up, boil it, and then steadily pour the entire thing down the drain.

The heat of the water is usually enough to remove scum and grunge, or separate small blockages so that the drain is left clear and flowing smoothly again. 

#2 Vinegar and Baking Soda 

This is a really good natural solution for tougher clogs, and it can work pretty well if you don’t want to use chemicals on your drain. First, pour a pot of boiling water down the drain to loosen things up a little, and then pour half a cup of baking soda down after it.

Let it sit for a few minutes before you get a cup of white vinegar and mix it with a little hot water and pour it into the drain. Leave it for around 15 minutes, and then rinse it out thoroughly with hot water. It also deodorises the drain to get rid of any odours that might be lingering.
