Beating Coastal Humidity: Stopping Waterline Scale & Pillow Mildew

Beating Coastal Humidity is a real challenge for Cape Fear owners, and staying ahead of it is what good hot tub maintenance is all about. If you’d rather skip the chemistry, our team handles it on a flat monthly plan.

Here’s what to know and do.

How humidity attacks your hot tub

Coastal humidity accelerates two problems: mineral scale along the waterline and mildew growth under the headrest pillows, where moisture lingers. Left alone, both get stubborn fast.

Keeping scale and mildew out

• Scrub the waterline on a weekly cadence.
• Remove and clean pillows, then apply a mildew inhibitor.
• Keep calcium hardness in range so scale doesn’t form.
• Air out the cover underside periodically.

Staying ahead of moisture is far easier than removing set-in scale and mildew later.
