At Froud Outdoor Services, we’ve helped countless homeowners keep their hot tubs running smoothly year-round. With years of experience, we’ve seen everything from sparkling clean spas to ones unintentionally damaged by common misconceptions. Fortunately, most of these issues can be avoided with the right care and expert advice.
Let’s clear up some of the most widespread hot tub myths so you can protect your investment and enjoy a safe, relaxing soak every time.

Myth 1: You Can Use Household Bleach in Your Hot Tub
Fact: Household bleach contains conditioners and detergents that can cause foaming, destabilizing water chemistry, and irritating skin and eyes.
For hot tub owners, knowing what not to put in your spa water is essential. Use only hot tub-specific sanitizers to maintain water balance, safeguard your equipment, and enjoy a clean, comfortable soak.
Myth 2: Antifreeze is Ideal for Hot Tub Winterization
Fact: Automotive antifreeze is toxic and should never be used in hot tubs.
While RV antifreeze (propylene glycol) can be used in some winterization methods, proper draining and blowouts are the preferred approach in freezing climates. This protects against freezing damage without introducing any overly harmful chemicals into your system.
Myth 3: An Ozonator Eliminates the Need for Sanitizers
Fact: Ozonators are excellent secondary systems, but they don’t fully sanitize your water.
They help reduce contaminants by preventing bacteria from multiplying but can’t keep water safe on their own. A residual sanitizer, such as chlorine or bromine, is still necessary to maintain clean, healthy water.
Myth 4: Pool Chlorine Tablets Are Safe for Hot Tubs
Fact: Pool chlorine tablets are not recommended for hot tubs. They are not formulated for use in small, heated bodies of water
Use hot tub-specific granular chlorine or bromine instead. These products are formulated for smaller water volumes.
Myth 5: You Can Clean Hot Tub Filters in a Dishwasher
Fact: Some manufacturers recommend using the dishwasher. But not all filters are created equal, nor will they necessarily get clean in a dishwasher.
A better method is to rinse filters thoroughly with a good nozzle on a garden hose or use cleaners that are specifically designed for hot tub filters.
Myth 6: All “Spa” Products Are Universally Safe for Every Hot Tub
Fact: Products labelled Pool and Spa are most generally Pool products and may not work properly in your spa.
Before adding anything to your water, check your manufacturer’s guidelines or ask your hot tub dealer. This small step can prevent costly damage and water chemistry issues.
