I sprayed 12% H2O2 in the house to clean mold. It's affecting me now. How can I remove/clean it or neutralize it?

Answer 1

If you have accidentally sprayed 12% hydrogen peroxide (H2O2) in your house and are experiencing adverse effects, it's essential to take immediate action to minimize the impact. Here are some steps you can take to remove, clean, or neutralize the hydrogen peroxide:

1. Ventilate the area: Open windows and doors to allow fresh air to circulate and ventilate the affected space. This will help dissipate the fumes and reduce your exposure to the hydrogen peroxide.

2. Evacuate the area: If you are experiencing severe symptoms or discomfort, it's advisable to temporarily leave the area and seek fresh air in a well-ventilated space.

3. Personal protective equipment: Put on appropriate personal protective equipment (PPE) before handling or cleaning the area affected by the hydrogen peroxide. This should include gloves, safety goggles, and a mask to protect yourself from further exposure.

4. Dilution and removal: If the hydrogen peroxide is present in liquid form, you can dilute it with water and clean it up using absorbent materials like towels or rags. Gently blot and remove as much of the liquid as possible without spreading it further. Avoid rubbing, as it may increase the fumes or spread the hydrogen peroxide to a larger area.

5. Cleaning surfaces: After removing the liquid hydrogen peroxide, clean the affected surfaces with a solution of mild detergent or dish soap mixed with water. Dampen a cloth or sponge with the solution and gently wipe down the surfaces to remove any residue. Rinse the cloth frequently and repeat the process until the area is thoroughly cleaned.

6. Air out the space: Continue to ventilate the area by keeping windows open and using fans to promote airflow. This will help remove any residual fumes or odors.

7. Seek medical assistance if necessary: If you are experiencing persistent or severe symptoms after exposure to hydrogen peroxide, it's important to seek medical advice or contact a healthcare professional for appropriate guidance.

Remember, hydrogen peroxide in high concentrations can be harmful, and it's important to handle it with care. If you have concerns or questions about the cleanup process, you may consider contacting a professional cleaning service or seeking guidance from local authorities or poison control centers for further assistance.
