A cleaner descriptively called Oh Yuk is formulated to clean bacteria, mold and slimy gunk called biofilm from jetted bathtub plumbing lines.
The cleaner targets the buildup that forms in the plumbing lines under the tub, where warm water tends to stagnate. Oh Yuk is added to water in the tub and run through the jets.
The manufacturer, Scientific Biofilm Solutions, recommends using the cleaner once a month.
The product can be ordered from CommercialPool.com, Amazon.com, PSTPoolSupplies.com or Wayfair.com. Prices range from $17.99 to $23 for a 16-ounce bottle and from $57.99 to $67.90 for one gallon.
