Oldwino I think you are mistaking.
Pot-meta is not a cleaning solution.
The strong solution is used for sanitsing your materials, bottles, hoses, racking canes etc.
It will not make things completely sterile but will kill enough bacteria to not contaminate the wine.
The smaller amount (like a campden tablet) is used for keeping the wine healthy and prevent it from oxidising.
For cleaning use something like soda ash or any cleaner and rinse will afterwards.
