Dear italianbruschi,

 

I'm having difficulty in understanding yr post. sorry.

 

What is product / process/  target item / material to sanitize ?

 

IMEX H2O2 is not a frequently used general sanitizer. And neither is nitric acid (very user unfriendly?). Maybe this is some special item / situation.?

italianbruschi,

 

 

Like Charles C., I misunderstood your request...

 

Anyway, I will post this interesting article about sanitation, perhaps it helps. If not, sorry... (perhaps you could explain it better)
