How to clean the dirt of stainless steel liquor tank

To clean oxides formed inside stainless steel tanks used for fermentation and refining, follow these steps:

1. **Use White Vinegar**: Pour a small amount of white vinegar into the tank and shake it well to ensure even distribution.

2. **Heat the Solution**: Heat the tank briefly to allow the vinegar's acidity to break down the oxides and salts on the tank walls.

3. **Inspect and Repeat if Necessary**: Check if the oxides have been removed. If not, repeat the process by adding more vinegar and heating again.

4. **Clean the Pipes**: After cleaning, ensure the inside of the pipes is thoroughly rinsed to remove any residual acetic acid smell, which could affect subsequent processing.

This method effectively removes oxides while preventing contamination from cleaning residues.
