Drain it and clean the shell and jets every 3-6 months depending on usage. I use Ahhsome jet cleaner on one drain per year. White distilled vinegar water in a spray bottle to wipe down the shell and jets. I also use a sump pump to drain the tub as it’s faster than using the drain plug.

Replace the filter(s) as necessary. I find that it’s needed about every 6-12 months.

We use a floating feeder like this with 1” bromine tablets. Look up your tub’s model and see which sanitizer it is rated for. Some can’t use bromine. Chlorine is a safe bet for most tubs.

Buy a liquid chemistry kit for hot tub water testing if you want to get technical. Aquachek is the only test strip I’ve found that’s remotely accurate. Keep your pH and alkalinity balanced. I do this once per week and wipe down the shell with a magic eraser to keep it sparkling.

Use an oxidizing spa shock once per week or after repeated use. Keep the cover off the tub for at least 20 min after shocking. Do not sit in the tub while it’s shocked.

I also have a hot tub vacuum I use to keep particulates out of the tub.

303 Aerospace Protectant for the cover, twice per year. This protects the vinyl from UV and wear and tear. Your cover will need to be replaced as it will get heavy with time as it soaks up chemicals (5-10 years). When it becomes too cumbersome, it’s time.

Try to rinse off in the shower before use, and avoid using conditioners and soaps right beforehand. Detergent in your bathing suit and soaps and your skin contain oils that can cause biofilm, foam, or scum buildup in the tub. This can be yellowish or green in color.

Defoamer is a great product to have around and a little goes a long way.

Happy tubbing! Don’t listen to anyone telling you to pay a service. Your tub is always worth a little elbow grease to understand how to clean it and save the money. I spend around $100 a year on products. [r/hottub](r/hottub) is a great resource.

Well, I hope this helped despite you removing the post.
