This conversion takes 5-days. The Natural Hot Tub Company® Penetrating Cleanser works well in removing past chemical build-up in hot tubs & spas equipment and lines. This water will have a higher concentration of chemicals used in the past and hot tubs & spas should not be used during this time. Please read instructions completely before starting.
- Remove filter(s) and leave out during this 5-day cleansing cycle. Purchase new filters if they are over 1 year old. Clean filters that are less than a year old with The Natural Hot Tub Company® Filter Soak.
- Add 1-full bottle of The Natural Hot Tub Company® Penetrating Spa Cleanser into your existing water, regardless of how old the water is or what chemicals have been used in the past. Be sure all jets are open. Two bottles are recommended if hot tubs & spas are over 5-yrs old.
- Maintain temperature at 90 degrees or higher & run filtration for a minimum of 6-8 hrs per day, 24-7 is best.
- After 5 days, turn off breaker & drain.
- Clean under headrests & bottom of cover with The Natural Hot Tub Company’s® Filter-Soak or Penetrating Spa Cleanser by using 1 capful to 1 cup of warm water.* This is a good time to inspect your cover for any tears, which would allow contaminated water to drip back into your spa water. If your cover has any rips or tears we highly recommend purchasing a new one.
- ‘Back Flush’ by shutting off spa drain, put garden hose into the filter area, and fill until bottom area of spa is full or at least 6-8 inches high. Rinse thoroughly and drain this water out.
- Plug the drain, put clean or new filter(s) back in, fill spa following new spa instructions and turn breaker on. Then complete instructions for New Spas.
*One part household bleach to 10 parts water can be used to clean cover and headrest. Baking soda or vinegar diluted with water is suitable for cleaning the interior of your spa. Never use anything with soap or anything which will leave a soap residue. Remember, unless you blow out your lines with an air compressor you will always leave 3 to 5 quarts of water inside your pipes and lines.
