- It’s always a good idea to clean your tub before you drain – add 4 ounces Cascade for every 100 gallons of water in the spa, (or your favorite automatic dish-washing detergent).
- Run the jets on high a few times.
- You can add 4 ounces of bleach for every 100 gallons of water to get it really clean.
- Drain after 4 hours or the next day.
- It doesn’t hurt a thing if you leave it in for a few days.
