purchased a couple of used ibc tanks and wondered what would be best way to totally clean the insides out before using as pure storage.
any chemicals i should use/ avoid?
i thought about spraying with virosol then blasting them out with brush and a jetwash.
i need to know they are sterile b4 i introduce pure to them as 2000ltrs down the drain would sadden greatly lol

My last one I just put some washing up liquid in there. Then left it a few days then emptied into my drain then filled it up everyday for a week with water and drained. Then filled with RO water and drained
