Hot Tub Cleaning Supplies: The Complete Beginner's Checklist for 2026

What Hot Tub Cleaning Supplies Do You Actually Need?

The essential hot tub cleaning supplies are a sanitizer (bromine tablets or chlorine granules), an oxidizing shock, pH and alkalinity balancers, test strips and a filter cleaner. Anti-foam, clarifier and scale control are add-ons you reach for only when a specific problem shows up.

That sounds simple, but a lot of retail shelves make it feel otherwise. Browse a typical spa care category page and you'll see dozens of products with little explanation of what each one does or which order to use them in. Beginners end up guessing. A traditional routine can involve 8 to 12 separate products, each with its own dose and schedule.

This guide explains each supply in plain language, gives you a printable checklist, and compares a multi-chemical routine with a once-weekly approach. If you want a broader overview first, start with our rundown of what chemicals you need for a hot tub.

Essential Hot Tub Cleaning Supplies and What Each One Does

Sanitizers

Bromine tablets for hot tub use dissolve slowly in a floater and stay effective at hot tub temperatures and across a wider pH range. Chlorine granules for hot tubs act fast and are dosed by hand, so they suit people who like precise control. In short, bromine tablets sanitize continuously, and chlorine granules sanitize quickly.

Our BroTabs bromine tablets are the set-and-forget option: drop them in a floater and let them work between treatments. If you'd rather use chlorine, always add granules to water, never mix them with other chemicals, and follow our guide on how to use chlorine granules for hot tubs safely. Still deciding? Our chlorine vs bromine comparison lays out the trade-offs.

Oxidizing shock

A sanitizer kills germs, but it doesn't clear everything. An oxidizing shock breaks down sweat, body oils, lotions and other organic waste that sanitizer alone leaves behind. Chlorine-free oxidizers also let you get back in the tub sooner after treatment. For more on this option, see our page on non-chlorine shock for hot tubs.

Anti-foam for hot tub water

Foam comes from oils, soaps, detergent residue in swimwear and low calcium hardness. Anti-foam for a hot tub works by breaking surface tension, but it treats the symptom rather than the cause. A few drops of defoamer clear the surface quickly, yet the underlying issue (residue, old water) still needs fixing. Read why your hot tub is foaming for the causes, and our hot tub defoamer guide for product advice.

Clarifier and scale or stain control

A clarifier binds fine particles together so your filter can catch them, which clears cloudy water. Our hot tub water clarifier article goes deeper. Scale control protects the heater, jets and pipes from mineral buildup, which matters most if you have hard water.

pH balancers and test strips

Aim for a pH of 7.2 to 7.8 and total alkalinity of about 80 to 120 ppm. Test strips are the cheapest supply you'll buy, and you should use them two or three times a week. Not sure how the two readings relate? Our explainers on pH levels in a hot tub and alkalinity vs pH cover it. Community threads like this Reddit discussion on chemicals for a new spa show that most new owners start with exactly these basics.

Filter cleaner

Rinse the cartridge weekly and deep-clean it monthly with a filter cleaner. Replace cartridges roughly every 12 to 24 months. A clogged filter makes every other chemical work harder.

Use this table as a printable shopping list. It shows what each supply does, how often you'll use it and whether a beginner needs it from day one.

Weekly vs monthly tasks

Weekly means testing, shocking and rinsing the filter. Monthly means deep-cleaning the filter and wiping the waterline. Every 3 to 4 months, drain and refill the tub. Owners in this Reddit thread on cleaning a hot tub describe much the same rhythm.

Cleaning without draining

You don't have to empty the tub every time it looks off. The same supplies keep water clear between refills, and we walk through the steps in how to clean your hot tub without draining the water. Manufacturers' own maintenance collections follow the same logic of sanitizer, shock and filter care.

Safety rules

• Never mix chemicals, especially chlorine with anything else.
• Add chemicals to water, not water to chemicals.
• Keep the cover open while dosing so fumes can escape.
• Store products dry, sealed and out of reach of children.
• Follow label doses every time.

More tips are in our hot tub safety tips.

Traditional routine vs all-in-one weekly routine

A multi-product routine means buying and storing many containers and dosing several times a week. For a closer look at cost and convenience, see comparing hot tub chemicals by price, efficacy and ease of use, and our overview of hot tub cleaning products. We also break down the five must-have hot tub chemical products.

The all-in-one approach cuts that down. TubTabs weekly cleaning tablets are a chlorine-free oxidizer with clarifier, foam control and scale control built in. They're not a sanitizer, so you use them alongside bromine, chlorine or another sanitizer system. BroTabs supply the bromine sanitizer.

The Hot Tub Complete Care Kit (15 TubTabs and 25 BroTabs) is $159.99 and is designed to last 3 to 4 months, versus $250+ for comparable multi-chemical setups. TubTabs are Canadian owned and made, include aloe for softer skin, and arrive at your door in the US and Canada, so there are no pool-store trips. If you already have a sanitizer, TubTabs Weekly Hot Tub Cleaning Tablets are $119.99 on their own.

Keep It Simple: Your Hot Tub Supplies Plan

Start with the essentials: sanitizer, oxidizer, balancers and test strips. Add anti-foam, clarifier and scale control only when a problem shows up, such as foam or cloudy spa water. Consistent weekly care matters more than a large shelf of products. If you like the idea of a calmer routine, our piece on hydrotherapy shows why a well-kept tub is worth the small effort.

For owners who want fewer steps, we recommend the Hot Tub Complete Care Kit at $159.99. It's Canadian-made, includes aloe, and ships to your door in Canada and the US.

Hot Tub Cleaning FAQ

What is the best thing to use to clean a hot tub?

The best approach is a combination of products rather than a single cleaner. Use a steady sanitizer (bromine tablets or chlorine granules), a weekly oxidizing treatment to break down oils and lotions, and a monthly filter cleaning. Drain and refill every 3 to 4 months, and wipe the shell with a cleaner made for hot tubs. TubTabs handle the weekly oxidizing, clarifying, foam and scale control step. Pair them with BroTabs for sanitizer, or choose the Hot Tub Complete Care Kit ($159.99), which includes both. Water-care guidance from spa technicians points to the same routine.

Why do you put a tennis ball in a hot tub?

A tennis ball absorbs surface oils on its fuzzy surface. It floats and soaks up body oils, lotion and sunscreen. It's a low-cost helper, but it doesn't replace sanitizer, oxidizer or filter cleaning.

How to treat hot tub after folliculitis?

Stay out of the hot tub until the rash clears. Mild hot tub folliculitis, caused by bacteria such as Pseudomonas in poorly sanitized water, often fades within days to a couple of weeks. Contact a doctor if the rash is severe, painful, spreading, or comes with a fever. This is general information, not medical advice. To prevent a recurrence, test and correct sanitizer and pH, shock the water, clean or replace the filter, and drain and refill if the water has been neglected.

Do hot tubs reduce cortisol?

Possibly, but the evidence is limited. Some small studies on warm-water immersion report lower stress markers and better relaxation, though results on cortisol specifically are mixed. Treat a hot tub as a relaxation aid, not a medical treatment. People with heart conditions or high blood pressure should check with a doctor before regular use.
