In brand new spas, Spa Marvel™ Cleanser removes residues leftover from the manufacturing process.Remove the spa filters.Add one bottle of Spa Marvel Cleanser into existing water. Run jets on high for at least 1 hour and then allow to circulate for another 23 hours. If your tub does not have a circulating pump that runs 24 hours a day, then you would need to leave the Cleanser in for a longer period of time to compensate for this. For example, if your spa is programmed to circulate 12 hours a day, then you would need to keep the Cleanser in for 2 days to achieve 24 hours of circulation (12 hours a day for 2 days = 24 hours, 8 hours a day for 3 days = 24 hours, etc.)Drain, flush (rinse the filter well, run water through each jet etc.), clean and thoroughly rinse the tub. Repeat before every drain and refill.Do not use the spa during the cleansing process.Clean both sides of the spa cover. If the cover is cracked or torn, we recommend it be replaced. The inside of spa covers have been known to harbor mould and bacteria, all of which drip from condensation through the cover back into the spa water.
