Hey All,
I've had an issue crop up with our non-caustic, sodium metasilicate/percarbonate based deteregent that shall remain nameless, after using it for years with same procedures and no issues.
Here's the problem:
Below the waterline everything looks great. Slightly above where the waterline usually is, there are white spots, raised, chalky splatter marks (not beer stone). After the acid rinse, after the tank dries, there are white streaks down the sides of the tank that are raised.
Here's the real problem:
After discussing this with my chemical supplier to get it corrected, he tells me
a)they haven't changed their formulation in the 15 yrs. we've been open. Maybe not, but I do remember them telling us years ago, after we reported a change in efficacy, that there had been a mixing issue at their plant.
b)that they've NEVER heard of an issue like this before from ANYBODY. This is sort of the reason for my post. The first call I made was to a brewer who it turns out had the EXACT SAME ISSUE a year or so ago, using a slightly different protocol.
Another brewer had to return some of this compound a few months ago. They noticed a difference in color, odor and that "it wasn't working."
I think I've figured out the splattering issue and can mitigate that with a few tweaks of protocol (although I still think it strange that it was never an issue before). Getting it off has been quite a challenge. This supplier has been offering suggestions, most of it has come down to elbow grease and a lot of acid (all kinds!).
I'm not trying to throw anyone under the bus. I'm just trying to figure out if there might be others who have had this problem, and especially any that have had it recently, say, in the last couple of months. I'm looking at going back to caustic, but was also curious about other non-caustic products, if anyone has any recommendations.
Cheers,
Travis
