For what purposes can a mixture of bleach and baking soda be used?

Laundering white clothes:

Add half a cup of bleach and half a cup of baking soda to your white laundry. The baking soda eliminates most of the strong bleach scent while boosting the bleach’s cleaning abilities. The result: whiter, fresher clothes. This is great for white clothes that have discolored with time.

Cleaning walls:

Mixing bleach and baking soda is also good for cleaning walls that are dirty and have molds. In a mixing bowl, pour a cup of baking soda and add just enough bleach to create a paste. Make sure to put on a face mask, gloves, and safety goggles as you’ll be using this on molds, which can create a chemical reaction. If the room doesn’t have a ventilation grate or fan, keep the doors and windows open.

Spread the paste on the walls and scrub with a stiff brush. Scrub until the mold is gone. Leave the room and wait for the paste to dry.

How can you add baking soda to bleach for washing white laundry?

The best thing about baking soda in the laundry is its ability to act as a natural boosting agent for bleach. You can use 1/2 cup of bleach and 1/2 cup of baking soda together for white loads. The baking soda masks some of the bleach smell and makes the bleach even more effective.

  • Next, in a separate bowl combine 1 part bleach with 2 parts water. Add mixture to a spray bottle.
  • Use the bleach solution to spray the affected areas in your bathroom. Let it sit and dry.
  • After the solution dries, respray the area with your bleach solution and this time get in there with a scrub brush.
  • Rinse the wall, and if you still see mold, go at it again repeating until the mold vanishes.
  • In some cases, grout or caulking must be replaced.

Why do you mix bleach and baking soda for household cleaning?

The main active ingredient in household bleach is sodium hypochlorite. In other household bleaches, hydrogen peroxide is the main ingredient. These two chemicals have strong cleaning capabilities and hence can be used for removing stains, cleaning laundry, walls and removing molds along with killing bacteria and other germs.

While washing clothes, a mixture of bleach and baking soda works so well because the chemicals in bleach break down the chemical bonds of a chemical called chromophore.

Chromophores are chemical compounds that give color to clothes, so the breakdown of these chemicals results in whitening of clothes and removal of stains or color.

Tips while cleaning with a mixture of bleach and baking soda:

Mix the two in a well-ventilated area:

It is always a good idea to mix both chemicals in a well-ventilated area. Opening windows while cleaning with bleach is always preferable. Make sure to let in as much fresh air as possible to avoid inhaling any dangerous chemicals and it also helps to dry the treated surfaces faster.

Dilute the chemical mixture with water:

Mixing the two chemicals will create a strong cleaning agent. It is quite strong and can damage some surfaces if it is not diluted with water. This tip doesn’t apply if you need to apply a paste.

Test the mixture on required surfaces before applying:

If you are using this mixture for the first time, it is better to test it on some surfaces such as any countertop, to check whether the mixture is too strong or too weak.
