There are a few things you can do to clean a horse stall:

  1. Remove all food and water from the stall. This will help to prevent any bacteria from growing and causing problems.
  2. Remove any manure or other debris that may have built up over time. This will help to clean the stall and remove any smells that may be present.
  3. Rinse the Stall with warm water and soap, then dry it off completely.
