The smell of hot tub covers can be irritating, but they're not the only thing that can smell bad about a spa. As moisture gets trapped between the outer surface and the plastic foam cores, it releases mold and other unpleasant chemicals.
If the moisture has penetrated the foam core of the cover, it can quickly grow dark and smelly slime, but it can also make the cover difficult to remove. This is the reason why a replacement spa cover is needed.
There are different reasons of Smelly Hot Tub Cover such as:
1. Broken or damaged.
A spa cover that has lost its roof line is prone to get damaged, and this will cause water to puddle in its place. Even with a duct tape repair, a spa cover with threadbare spots will eventually need to be replaced.
2. Not Removed Regularly.
It's a good habit to remove your spa top every week for 2 hours of air circulation. A better cover can endure longer periods, but it's also a good idea to remove it every time you want to use it.
3. Poorly Made.
Tape and staples are easy to make a good spa cover, but they won't stop the moisture from coming in. Instead, invest in a quality foam panel with a heat welded seam and a thick vinyl layer.
4. Bad Spa Water.
The water in your spa should be regularly filtered and treated to prevent algae and bacteria from growing. Also, keep the underside of your spa cover clean to prevent staining.
5. Not Cleaned / Conditioned.
Not Clean / Conditioned. If your outdoor spa is located in a gazebo or your back deck is covered, then it should be treated with the same care and attention that it would receive if it was in a pool or a patio.
Fix Your Hot Tub Cover!
- Remove to Safe Location: Ideally, the cover should be placed in a safe location away from pets and wild animals. This can be either a sunny location or a dry indoor space.
- Deodorize & Disinfect: Do not use harsh cleaning products on your spa cover. Instead, use a spa cover cleaner that is specifically formulated for the job.
- Remove the Panels: Don't Use the Panel: This step should be avoided if possible, as it could damage the panels. However, if possible, remove the panels and allow the cleaning to take place.
Use a Spa Cleaner Cover to clean and deodorize your spa. It removes most stains, including tree sap and bird poop. It's also effective at repelling dirt.
Mildew or mold may still be present on the surface of the spa. If the issue is still significant, dilute a bit of bleach with a few cups of water.
It's important to use as much water as possible on the spa's cover. Ideally, it should be at least twice per year. However, if it's in the open, it should be at least four times per year.
A new spa cover is often the easiest solution to avoid getting a smelly spa cover. It's a good idea to get one if the cover is more than five years old.
