Mixing water, hydrogen peroxide, and bleach together is not recommended and can be hazardous. The combination of these substances can produce potentially dangerous chemical reactions and release toxic gases.
Hydrogen peroxide (H2O2) is a mild bleach and can be used as a stain remover or disinfectant on its own. However, mixing hydrogen peroxide with bleach (which contains sodium hypochlorite, NaOCl) can result in the production of chlorine gas (Cl2), which is highly toxic. Chlorine gas can cause severe respiratory irritation, coughing, breathing difficulties, and in high concentrations, it can be life-threatening.
It's important to follow the instructions on cleaning products and use them as directed. If you need to remove stains, it's best to use one cleaning agent at a time and avoid mixing different chemicals together. If you're unsure about a particular stain or cleaning method, it's advisable to consult the instructions on the product's label or seek advice from a professional cleaner. Additionally, always ensure adequate ventilation when working with cleaning agents and avoid inhaling or ingesting them.
