On the other hand, it is not as strong as the other options, such as bleach and other cleaners. Since it is a weak acid, you may need to soak your filter in the solution longer. Sometimes, it may not clean your hot tub filter well enough if it is extremely dirty.

Which Vinegar Should You Use to Clean Your Hot Tub Filter?

I should mention that there are different kinds of vinegar, including apple cider, white distilled, balsamic, and red or white wine vinegar. Which kind of vinegar is best for cleaning your hot tub filter?

Of all the different types of vinegar, the white distilled vinegar stands out when we talk about cleaning. Some people call this “white vinegar.” The vinegar solution contains around 10 percent acetic acid and 90 percent water.

White distilled vinegar is the best cleaning agent because it doesn’t stain like the other darker-colored vinegar. The acidity level of this vinegar is also comparable to that of the other multi-purpose cleaners.

White distilled vinegar is also the most common type of vinegar that you will find in your kitchen cabinets. Therefore, you do not need to take a special trip to the store to purchase a bottle of vinegar for cleaning.

Apple cider vinegar is also another option next to white distilled vinegar. This type of vinegar also contains good cleaning properties. Furthermore, it also contains anti-bacterial properties.

How Much Vinegar Do You Use to Clean a Hot Tub Filter?

The size of a hot tub filter varies. The amount of vinegar you need to clean your hot tub filter will depend on the size of the filter. The goal is to soak the filter in the water and vinegar mixture completely.

But how much vinegar exactly do you need? How much water? What is the mixture ratio?

Some people mix 2 cups of vinegar for every 4 cups of water. This ratio could work if your hot tub filter is mildly filthy. However, you can make your solution stronger by mixing an equal amount of water and vinegar. 

The 50/50 mixture of water and vinegar should be good enough to loosen the dirt and mineral deposits on your hot tub filter. This ratio is also the ratio that most people use. If you think your filter has a stubborn scale, you can adjust the ratio to make your solution a little stronger.
