Can You Use Hydrochloric Acid To Clean Toilet Bowl?

You deserve to sit in a clean toilet, so you must stay on top of things to ensure you have the necessary supplies to remove debris and stains. There are many varieties of toilet cleaners, but this post aims to examine cleaning a toilet bowl with hydrochloric acid.

With hydrochloric acid, your toilet bowl will be sparkling in no time, making it not only hygienic but also pleasant.

Can Your Use Hydrochloric Acid To Clean Toilet Bowl?

Hydrochloric acid helps clean toilet bowls because it removes grime and dirt effectively, leaving your toilet stain-free. While you could try removing stubborn stains with vinegar, which is much safer to handle, you must consider using the much stronger hydrochloric acid if the problem persists. 

However, since hydrochloric acid is a strong acid, it’s highly corrosive, capable of destroying metal, burning skin, etching stone, and even stripping away enamel. Therefore, you must handle it carefully and don’t use it regularly for the sake of your toilet and drainpipes.

How To Safely Handle Hydrochloric Acid When Cleaning Your Toilet Bowl

Hydrochloric acid is a potent chemical that can hurt your eyes and skin and damage your bathroom floor or anything else it comes into contact with, so you must handle it carefully. Here are the safety precautions to follow if you use hydrochloric acid to clean the toilet bowl.

  1. Put On Protective Gear

Before handling hydrochloric acid, put on chemical splash goggles, chemical-resistant gloves, and a chemical-resistant apron to protect your skin and eyes. In addition, inhaling this acid can cause breathing issues, especially if you are asthmatic, so put on a mask to avoid breathing in the fumes.

  1. Keep Your Bathroom Ventilated

The fumes from hydrochloric acid can be harmful to your respiratory system, so you don’t want them concentrated in your bathroom. Therefore, run the bathroom fan before cleaning your toilet bowl with the chemical. 

  1. Clean Any Spills Immediately

You don’t want the hydrochloric acid you spilled on your bathroom floor or any other surface sitting there for long, thus causing corrosion. Therefore, clean up the mess immediately to protect your property.

Sprinkle a generous amount of baking soda over the stain if it’s recent or fresh. If the stain is much older, mix water and baking soda to create a thick, consistent paste and cover the entire stain with it. 

Once you do so, let it rest for a couple of minutes, then wipe it using a cloth.

  1. Follow The Manufacturer’s Instructions

On the container with the hydrochloric, you will find the manufacturer’s instructions on how to handle the chemical. Make sure you follow them precisely for your safety and to avoid damage.

  1. Store The Acid Well

Set aside a wooden cabinet to store hydrochloric acid and ensure your kids don’t have access to it. Avoid a metallic cabinet because the fumes from hydrochloric acid corrode metals.

In addition, label your acid bottles to avoid mixing them up. 

  1. Handling Hydrochloric Acid Exposure

Get medical attention immediately if hydrochloric acid comes into contact with your eyes or skin. If your skin is exposed to acid, rinse the area with clean water for about 15 to 20 minutes.

You should also rinse for at least 15 to 20 minutes if it gets into your eyes. Additionally, remove your clothes if acid gets on them before it soaks into your skin.
