How do you dispose of hydrogen peroxide?
Answer:
Dump it in your toilet or tub overnight. By morning it will have removed some crud from the tub or killed a bunch of germs in the toilet and transformed itself into water and oxygen which will dispurse in the air.
I would say it would be okay to pour it down the drain. hydrogen peroxide (H2O2) will turn into water (H2O) and oxygen if exposed to light or organic material, which is why it comes in a brown bottle.
It will clean your pipes too!
I found this online:
Disposal: Unused or unwanted portions of household hydrogen peroxide should taken to a hazardous household waste collection center. If a collection center is not available, 3-5 % peroxide solutions can be flushed down the drain. If you use a septic tank or lagoon, dispose of small quantities over several days. For information about disposing of 10% peroxide solutions, contact your local fire department or wastewater treatment plant.
