For a long time I have been looking for ways to clean our storage areas and could not find a solution that would be safe and effective. It's good that we were advised to pay attention to the article https://www.fortador-usa.com/blog/top-best-heavy-duty-industrial-steamers-for-cleaning-choosing-industrial-steam-cleaner which describes the cleaning process using a heavy duty industrial steam cleaner and now we use steam cleaning as it is safe and no need to use chemicals.
