Hey everyone, I have a question about drain cleaners. What is their pH level? Are they acidic or alkaline?
Also, how does the pH affect their effectiveness in unclogging drains? Which type is safer and more effective for home use?
Looking forward to your answers. Thanks!

Hi @johnbruce1
Most drain cleaners are on the high side of the pH range usually 11.0+ (up to 14 which is max range for pH), which means that they are alkaline.
They are effective at cleaning drains because they dissolve the greases etc, but they can also damage plastic and older metal pipes so they need to be used cautiously.
They are not effective if the drains are being clogged by tree roots etc.
The higher the pH level the stronger the cleaning effect is but also perhaps the damage it can cause.
Looking at a few commercially available products they don't specify the pH level on the label so you wouldn't know what it is.
Best option is to watch what is put down the drain and try to minimize clogs from occurring, e.g. use sink strainers, don't pour cooking fats down the drain- allow to solidify and then scrape off pots etc and dispose in garbage bin etc. Also follow the 3 P rule for toilets i.e. pee, poo and toilet paper only to be flushed, nothing else.

Most are caustic and chlorine based which breaks down greases and proteins.
If the water is flowing you likely want to use a foaming type so the full pipe wall is covered, not the bottom alone.as the longer it sits on the clog area the better.
