If you are looking for some spa servicing tips, maybe this will help you.
The first thing that you want to do is clean your spa. To clean the shell, use a mild, non-sudsing cleaner and a rag to remove dirt build-up. Baking soda can also be used for minor cleaning. After cleaning and drying the shell, apply FreshWater Spa Shine to make your spa look like new. The hot tub cover is cleaned and conditioned by doing this step-by-step instructions: first, remove the cover and wash it with a hose to get rid of dirt or debris on it. Using a soap solution to scrub the vinyl. Then rinse it with a garden hose. Rinse the bottom but do not use soap and wipe it dry with a rag. After you clean it you might want to condition the cover. To do this you should apply Hot Spring Cover Shield™ to it.
Another thing that should be done is cleaning your filter cartridges. The spa filter cartridges can become clogged with mineral particles, etc. which may result in a lower water flow. So, you should clean your filter cartridges every month. Using a hose, spray each cartridge to remove any debris that is between the filter pleats. Use FreshWater Filter Cleaner to keep your filters clean. Your filters should be replaced every three years so they will work properly.
The water that is in your hot tub should also be replaced every once in a while with fresh water. You need to drain your spa water and refill it according to the instructions in your Owner’s Manual to eliminate soap film which may be in the spa water. For clean water right from the start, you should use the CleanScreenTM; Pre-Filter when filling up your spa. This filter removes organic contaminants, metals, and tannins before they make their way into the water.
So if you maintain your spa and keep it looking like new, it will last for many more years to come.
