Add Clorox Spa System Cleanse to remove debris from the plumbing. Run the pump to ensure it reaches all sections of the lines.
Turn off the power, then drain water from the spa using a hose attached to the spigot at the bottom of your tub.
Remove and clean the filter as you normally would. Replace it if it is worn or torn.
Wipe down tub surfaces, headrests and tub exterior or enclosure.
Add fresh water through the filter reservoir to remove any debris before it enters the system. Make sure power is turned off and close all spa drains.
Test & Adjust
Follow the usual testing routine to balance water and get sanitizer levels in the accepted range.
