Hydrogen Peroxide (3%) Will NOT Clean Your Home

There are websites touting that H2O2 can be used to clean just about everything HydrogenPeroxidein your house. Really? It has many uses, and the information about H2O2 has been around a while, but sanitizing your bathroom or kitchen are not part of those uses. You’ll see why in a moment. My degree was in hazardous waste,  so I’m a bit alerted on the subject of toxic chemicals. Additionally, I’m not eager to jump on the bandwagon of new information from the internet until I get the research.

Here’s some quick information about Hydrogen Peroxide:

  • Household grade is 3%
  • It’s an oxidizer and corrosive to humans (meaning it can cause destruction of human tissue depending on strength, length of exposure, and part of body exposed.)
  • Is not recommended to ingest or take even diluted over a period of time as a mouth rinse. Use with caution. Use responsibly.
  • In order for household grade to actually disinfect hard surfaces, it must remain on that surface wet for 6 – 8 minutes before significantly reducing household germs.

That’s just too much waiting time for me.

Scroll down to the header Hydrogen Peroxide on this page: CDC – Disinfection

I know it may read like scientific and math gibberish, so here’s the gist of it:

“In an investigation of 3%, 10%, and 15% hydrogen peroxide for reducing spacecraft bacterial populations, a complete kill of 106 spores (i.e., Bacillus species) occurred with a 10% concentration and a 60-minute exposure time. A 3% concentration for 150 minutes killed 106 spores in six of seven exposure trials 658. A 10% hydrogen peroxide solution resulted in a 103 decrease in B. atrophaeus spores, and a >105 decrease when tested against 13 other pathogens in 30 minutes at 20ºC.”

Don’t confuse Clorox brand Hydrogen Peroxide Disinfectant with household H2O2.  According to the Clorox Company:


“Prior to the development of improved (emphasis mine) hydrogen peroxide, standard hydrogen peroxide was not considered a practical disinfectant for hospital use due to its instability. However, scientific advances have been made to the formulation of hydrogen peroxide products to associated weaknesses such as instability, limited antimicrobial efficacy and long surface contact times.”

Don’t let “instability” scare you. It just means it didn’t work in that environment for hospital disinfecting needs.  And…

“Clorox’s hydrogen peroxide healthcare products are ready-to-use and combine hydrogen peroxide with activators, stabilizers and surfactants to offer fast-acting solutions that are noncorrosive and compatible with many healthcare surfaces and medical equipment.”

If you use this type of cleaner, wear gloves.

Personal resolution: There are a variety of simple,natural and effective cleaning recipes all over the internet. Sometimes I will concoct them. For fast, aggressive germ killing, I use all-purpose bleach spray.
