Can bleach be mixed with washing soda? (2025 Update)

Use 1 T. dishwashing liquid, 1/2 c. household bleach and add warm water to make 1 gallon. Use this to spot clean off the mold spots. Then clean the entire wall (from bottom to top) with a mild soap solution and warm water. If your walls are really dirty use TSP. Clean the entire wall, then rinse the entire wall with clear water, and rinse again. Rinsing is an important step for the paint preparation. You will need to protect the floor/carpeting, plus turn off the electrical outlets.

I do not recommend washing soda nor Oxiclean. But to answer your question, it is safe to mix washing soda and household bleach.

Lowes recommends bleach and dishwashing liquid for outdoor decks, but the MSDS for Dawn says it's unsafe:

Then I read that the State of California had paid for testing bleach and baking soda. It worked for me. It was easy on my hands and cleaned ziplock bags better than anything else. Bottles came clean quickly with no lingering suds or odor.

It also works on stained surfaces. I don't recall using bleach and baking soda outside the kitchen and bathroom because I've had good luck with borax or borax and ammonia on mildewed paint. Now that casioculture has mentioned washing soda and bleach, I think I'll try baking soda and bleach the next time I clean mildewed paint. The latter mixture would have a lower pH, which would make it easier on the hands and help the bleach work faster.

Watch the pressure build up when you mix washing up liquid and bleach in a bottle and shake. It can be extremely dangerous. I soak my sink with hot water, washing soda, bleach and washing up liquid then bung in any dishcloths or tea towels, scrubbies etc. every night.

At the time, I didn't know anybody had ever said it was dangerous, but I threw a lot of bottles and ziplock bags away because washing them that way didn't work very well.

Do those three substances complement each other?

American bleach is typically 5 or 6% sodium hypochlorite in water. What's yours?

Are you familiar with baking soda (sodium bicarbonate)?

I think they do. However - my sink cracked this week, I find it hard to believe any chemical has done that or weakened it, more like someone dropped a saucepan or heavy container. Boiling water may have cracked it and I did drain the potaoes in it the day before.

I don't have a bottle to hand, I will let you know

of course. mixed with bleach it brought my sink up a treat. Don't suppose that would have weakened it? ;-)

what do you mean when you say "washing soda" never heard thsi term before. A couple of product names would be helpful. Have never heard of a sink cracking....more likely something heavy dropped in it. Cannot imagine draining boiling water would do such a thing.

I doubt the brand names I give will be of much use. I used to use ICI washing soda crystals but can't get that now. This page has the one I use now on

Washing soda is sodium carbonate

It's actually more powerful than baking soda for some things */(though don't use it for cooking!)/*; I've used it, along with dish soap and borax, to degrease rags, and even a stove hood fan that hadn't been washed for an Age of Man.

Washing Soda (sodium carbonate, or "soda ash"), can also be made by heating Sodium Bicarbonate to 400 degrees F for 1 hour, mixing, and heating for another hour at 400 degrees F.

What the hell is "washing up liquid" supposed to be? That is not the name/term for any kind of cleaner. Do you mean "dish soap?"

It’s what we call dish soap in the UK. You do know it’s okay for one thing to be called different things? The American term is not the only one or the right one.
