Sanitizing with San Step
There are two questions that come up when introducing San Step to a new user, and we will address both of them here. The first question is, “How do I get the most out of San Step in use?”
First, to maximize efficiency, use the proper dilution rate, which is 1 oz per 6 gallons of water. By doing so, you immediately save 20% as compared to the leading national brand of acid sanitizer, which calls for a dilution of 1 oz per 5 gallons. If your water is below 50 degrees Fahrenheit, San Step will have a hard time going into solution, so make sure your water is warmer than that.
Secondly, make sure that you clean everything with a good alkaline cleaner such as AmBrew Cleanser or Straight-A. (You can certainly use One Step as well, but that product is designed to take on the role of both cleaning and a final rinse for home users– see our page on using One Step for more information. Basically, we tend to focus and the big guns of our stronger cleansers when we’re using the big gun of San Step.)
Finally, after you clean, rinse with water, and then use your San Step sanitizer and ensure 1 minute of wetted contact time. Wetted contact time means that you can spray a surface or swirl the solution through a vessel and ensure that it is wet during that time. If you are using a recirculating or clean-in-place (CIP) system, allow 2 minutes to ensure that all the nooks and crannies are penetrated.
There is a chance that your solution will be cloudy. If that is the case, it is probably because you used more than the recommended level of sanitizer or that your water is too cold. If the water is too cold, warm it up and all will be fine. If you used too much sanitizer, it’s fine; the solution is still active and what you are seeing is an intermittent aggregation of the fatty acids (they come together and then they move apart). You will not see the biocide precipitating out like you would see with other acid sanitizers.
And how do you make sure that the solution is still good? As long as it stays visibly clean (which it will because you will always clean and rinse prior to using your San Step solution) and the pH is below 4, your biocide solution is active!
The other question that comes up when introducing people to San Step is, “Why does it behave so differently than that high foaming acid sanitizer?”
To that question, we often ask our own, which is, “How much chemistry do you want?” And that is the question we are posing here now, because we’re really not sure if the detailed explanation is something that our customers are interested in. If you are, let us know and we will answer your query and, if enough people ask, we will probably put the answer here on this page (complete with molecular structures and the explanation of resonant charge effects)…
