Hydrogen peroxide is a good drain cleaner

H2O2 (hydrogen peroxide) harmful to drains and pipes?

  • Hi,
    I just desenfected an old aquarium of mine with a 3% H2O2 (hydrogen peroxide) solution and now I am wondering whether I can simply dump the H2O2 into the sewer pipe of the sink or whether it eats a hole in the pipe or something. Can anyone help me with the question?

  • Hi,
    at 3% nothing happens except that it may foam a bit. The H2O2 also disinfects the tube but does not eat any holes;)

  • Fast answer Christina Thanks, then I can throw it away now

  • Hello,
    I have a question about that. Do you want to pour the H2O2 out of the basin or the rest in the bottle?
    I think you mean what you disinfected the pool with? If so, then you can throw it away without any problems, since hydrogen peroxide converts into water and oxygen when it comes into contact with air

  • Hi,
    I poured the desenfication stuff onto a plate and wanted to venture the rest on the plate.

    Doesn't it convert into oxygen and water when it comes into contact with water, otherwise it would be bad to desenfect

  • Hi
    I think you don't have to worry about that. I recently asked at the pharmacy if I could bring the empty bottles of 30% hydrogen peroxide (I mix it down to 3% myself) back for disposal. The answer I got was that I should simply rinse the empty plastic bottles well and then I could dispose of them in the household rubbish. The hydrogen peroxide would be so diluted in the drain that it doesn't matter, Danme explained to me.
