Cold Plunge Scum & Body Oils

Cold plunge water picks up sweat, body oils, skin products and other contaminants every time it is used. Those materials can collect at the surface, waterline and filter.

Prevent buildup before it starts

• Shower before entering when possible.
• Keep the plunge covered between uses.
• Maintain the filter on schedule.
• Wipe the waterline regularly.
• Follow the treatment method approved for your specific plunge.

If scum builds up quickly

Heavy or recurring residue can be a sign that the water is carrying too much contaminant load for the current maintenance routine. Clean the vessel and filter and consider whether a water change is due.
