I and probably a lot of people using HHO systems would like to know is --- what is the difference in Sodium Hydroxide food grade verses Sodium Hydroxide in drain cleaner? And the Sodium Hydroxide provided by the HHO company. You can buy the drain cleaner that has 100% Sodium Hydroxide locally but have to order food grade Sodium Hydroxide on the internet or from the HHO company of your HHO kit.
Thanks, Duane Darrah
