By doing this, you will allow your hot tub filters to work more efficiently and last longer. This only takes a few minutes and should be done at least once a week if you use your hot tub regularly.

Then, Rinse them down with clean water. Spray the filters down with the cleaner and let them sit for about 15 minutes. This will allow the chemical to sink in and do its job. Then with clean water, rinse the filter thoroughly until all the soapy substance is gone. Make sure you rinse the filters well. Filter cleaner sprays can cause a lot of foaming in your tub when you put the filters back in.
- The Chemical Soap: Use a hot tub filter soak chemical, DO NOT USE HOUSEHOLD CLEANING PRODUCTS dilute the chemical with water according to the directions on the bottle. Make sure you use enough water to completely submerge one filter. If you have room, you can add more filters to the solution. Let the filter rest in the solution overnight or 24 hours. After soaking, be sure to rinse the filters very thoroughly with clean water. Again, you don’t want foamy hot tub water.

Winter hot tub maintenance
If your tub is going to be left empty over the winter months or in any very cold climate where there is a possibility of sub-zero conditions it is very important to remove all the water from the pipework and pumps as well as from the tub itself.
Water that freezes in the pipework and pumps can expand and crack the pipes and pump wet ends leading to major leaks which will leave your tub unusable and will need an engineer to repair.
Frost damage is not covered in the warranty on your tub.
Check the water level in your tub regularly and top up as necessary.
If you keep a check on your water and chemical levels either every day or each time you use the tub and add the necessary chemicals, you should be able to keep your water in the tub for up to three months.
After three months it is recommended that you drain the tub, clean the shell and jets and then refill with clean water.
