Used to do this with a tin can full of potassium permanganate (potassium manganate 7 in newspeak). Just heat it till it’s white then put it back after it’s turned purple from absorbing water (I.e. recycle it)
Not even sure if you can buy it now, it’s useful for nefarious things. Used to be in survival kits, it’s a fire starter, disinfectant and mouthwash too.
