Spa Cover Care & Prevention of Mildew

CARE OF THERMAL COVER

The thermal cover for your spa is a durable foam insulation product. Monthly cleaning and conditioning is recommended to maintain its beauty.

To clean and condition the vinyl cover:

Remove the cover from the spa and gently lean it against a wall or fence.
With a garden hose, spray the cover to rinse away and loosen dirt or debris.
Using a large sponge and/or a soft bristle brush, and using a spa cover cleaner or shampoo.
Scrub the perimeter and side flaps of the cover and then rinse clean.
Rinse off the bottom of the cover (using a spa shampoo) and wipe clean with a dry rag.
To condition the vinyl cover (after cleaning), apply a thin film of spa protectant, following the directions on the container. This will reseal the vinyl and damaging effect of the sun’s rays.
Place the thermal cover on the spa and fasten the cover tie-downs.

SERVICE NOTE:

To remove tree sap, use lighter fluid (not charcoal lighter but the kind used in cigarette lighters). Use sparingly and immediately afterwards, rinse with a saddle soap solution and wipe dry.

WHEN TO CONSIDER REPLACEMENT:

If your cover is worn, heavy and waterlogged, it has lost most of its ability to insulate, and will run up your power consumption. Consider replacement with a quality cover. Don’t waste your money on a cheap cover that will only last a year or two.

Warranty defects do not include:

Material abrasions due to misuse.
Minor cosmetic color changes.
Rotting threads or vinyl due to excessive chemicals.
Vandalism.
Foam breakage or moisture retention due to natural absorption of condensation.

IMPORTANT USE REMINDERS:

DO remove snow build-up to avoid foam core breakage.
DO unlock and release all straps before removing cover.
DO cover the spa with the thermal cover when the spa is not in use, empty or full.
DO NOT walk, stand, or sit on the foam insulated cover.
DO NOT drag or lift the spa cover using either the flaps or the tie-down straps. They are not designed to be used as handles.
DO NOT use any chemicals or cleaners except those specially made for spa cover care. Products containing silicone oils will degrade the vinyl and cause harm to vinyl.
DO NOT allow small children to play on the cover.
DO NOT allow children to use the spa unsupervised.
DO inspect the cover for premature wear or deterioration.
DO replace cracked or broken foam inserts.
DO keep cover locked when spa is not in use.
DO avoid exposing cover to excessive chemicals — remove cover when adding chemicals.
DO avoid scraping the cover on abrasive surfaces.
DO avoid exposing cover to extreme heat and cold (-20F°/150°F) and stress conditions which could result in tears or other damage.
DO NOT jerk or pull the cover, especially when vinyl is softened by heat, to prevent threads tearing the vinyl. All water or snow must be swept off or kept from accumulating or puddling on the cover. Children can drown on top of the cover.
DO remove all fallen leaves or other debris immediately to avoid color leaching.
DO remove all debris first when opening the cover.
DO gently fold one side onto the other. Never forcibly open or flip the cover onto one side.
ALWAYS remove cover completely. Never enter the spa with the cover on. ENTRAPMENT IS POSSIBLE!
ALWAYS remove and replace cover by using the handles.
ALWAYS secure cover on spa — improperly secured covers are a hazard.
DO have water chemistry tested by a professional. Any texture change or extreme discoloration of bottom material indicates chemical burn.
DO replace foam inserts — if the foam inserts become cracked, heavy, or damaged in any way to avoid further damage to the cover.

PREVENTION AND REMOVAL OF MILDEW:

Mildew can occur on spa covers when a spa is not kept clean or pH controlled, and the result could be permanent damage to the cover. Usually you can see the mildew or smell it.

To prevent mildew, keep the water balanced properly. Once you have mildew, the following should remove it. However this option may or may not work due to the age of your cover, stitching condition, and core condition. Core may not fit back into encasement:

Mix one cup of bleach, a teaspoon of dishwashing soap to one gallon of water.
Scrub the inside of the jacket thoroughly using a soft bristle brush.
Wipe down each foam core with a washcloth.
Rinse both thoroughly.
Place the jacket in the sun and the foam cores in the shade to dry (foam cores can melt in the sun). – Replace core back into the encasement as soon as possible.
As soon as it dries, spray the cores and the jacket with a mildew inhibitor such as Pine Sol.

Reassemble and put back on the spa. Do not leave unassembled any longer than necessary as the vinyl encasement could shrink which could result in the core not fitting back into the encasement.
