Shell Surface Cleaning
Cleaning Above the Water Line
The perfect product for cleaning the shell surface above the water line (when the spa is filled) is ThermoSpas’s
Multi Purpose Cleaner. This helps to prevent a scum line from forming. Because it is a natural enzyme, it will not
affect the water’s chemistry, it’s safe to use, it won’t scratch the acrylic, and it helps to eliminate mold or
mildew odors without bleaching the surface.
Beware of using products such as Windex, as they will alter the water’s chemistry; or
other abrasive cleansers that can scratch the acrylic surface.
Step 1: Spray the exposed surface area of the shell above the waterline with Multi Purpose Cleaner.
This will not affect the water chemistry.
Step 2: Wait a few minutes and then simply wipe away the grime with a soft cloth or damp sponge. For
heavily soiled areas, spray generously, wait five minutes and scrub with a two-textured sponge.
ThermoSpas offers an accessory called the Mytee Mitt, which is perfect for this use.
Deep Cleaning the Entire Shell Surface
Anytime the spa is drained and dry, we recommend two products when cleaning the entire shell surface:
ThermoGloss and Multi Purpose Cleaner. ThermoGloss helps create a hard, durable, protective coating on the
shell that seals the surface and hides scratches in the acrylic. Multi Purpose Cleaner is ideal for ridding the
surface of any dry residue.
Do not use car wax of any kind.
Step 1: Remove any scum lines using Multi Purpose Cleaner.
Step 2: Shake ThermoGloss well before using and apply only on the shell surface. The surface should be
completely dry upon application.
Step 3: Spread evenly using an overlapping circular motion.
Step 4: Allow the ThermoGloss to dry, spray Multi Purpose Cleaner on the dry residue left by the
ThermoGloss, and wipe the shell surface clean with a dry, soft cloth.
Cleaning the Cover
While your vinyl cover is made to withstand the elements, it is important to care for it by keeping it clean at
all times. Many contaminates may stain the vinyl if left on over a period of time. Remove stains immediately!
Conditioning the Cover
Conditioning the spa cover monthly will prolong its life. We recommend using ThermoSpas Cover Conditioner. It
helps keep vinyl from hardening and cracking, and is especially effective for covers exposed to harsh outdoor
elements like the sun’s ultra-violet rays, snow, and sleet. Cover Conditioner should only be used on the topside of
the cover. To clean the underside of the cover simply use a garden hose and a 2:1 mix of water and vinegar. Allow
cover to dry.
Step 1: Apply ThermoSpas Cover Conditioner full strength with a damp sponge or soft brush.
Step 2: Leave the conditioner on the cover for three minutes. Areas with excessive dirt or residue build-up
may need extra scrubbing.
Step 3: Wipe the cover clean with a damp sponge or cloth.
Step 4: Rinse the cover with water.
Do not use petroleum-based vinyl cleaning products because they may be harmful
to the cover and will void its warranty.
Flushing Lines
There are many plumbing lines in a spa. No matter how clean you keep the water, chemicals clean only the water,
not the plumbing lines. Bacteria and mildew-attracting scum can accumulate in the vast number of spa plumb-
ing lines and fittings. You need to flush and clean them to prolong the life of your spa and keep it running
smoothly.
Flushing and cleaning needs to be done every 6 months to one year, or if you notice a film developing around
the spa fittings. You should perform this procedure just before you drain your spa. We recommend using
ThermoSpas Jet Line Cleaner to dissolve the build up of body oils, dirt, hair, soap, scum, rust and mineral
deposits which are the perfect breeding ground for bacteria and mold.
Step 1: Remove filter(s) and clean.
Step 2: Before spa is drained, empty contents (16 fl. oz.) of ThermoSpas Jet Line Cleaner in to warm spa water.
Step 3: Turn pump(s) “on” and run jets for 15 minutes. (Ensure filter is not in spa and cover is closed.)
Step 4: Turn pump(s) and jets “off” and let sit for 1 hour.
Step 5: Turn pump(s) “on” and run jets & blower for 15 minutes.
Step 6: Drain the spa, hosing off the inside walls while draining.
Step 7: Refill the spa.
Note: Some residual foaming may occur, if so, use ThermoSpas Foam Away to suppress foam.
