There are mulitple ways to clean a hot tub filter and all are effective, however you will get different results with each method. Right off the bat I’ll begin by saying what not to use. Do not clean your hot tub filters with: Laundry Detergent Car Wash Hand Spa Dishwashing Soap Or Any bubbly soap for that matter. These methods will clean but not santize, plus if you don’t rinse them off good enough it will turn your spa into a bubble bath and you wouldn’t want that mess. I would recommend using any of the following methods for cleaning your hot tub filters.
Hot Tub Filter Cleaner
This is a simple degreaser that you can find at most pool and spa stores. It can be used it two ways. You can dilute it with water and soak your filters overnight. Or if you want to make it a bit quicker you can put some in a spray bottle and generously spray down your hot tub filters and let them sit for about 15 minutes or so and hose them down with water. Note: Make sure you hose them down extremely well, degreaser can cause bubbles and bubbles means a ton of foam in your tub.
Muratic Acid
This is the old fashioned way of cleaning hot tub filters. Simply dilute some muratic acid with water and soak your spa filters overnight. You can find muratic acid at your local pool and spa store.
Note: Muratic acid is ACID! It burns like crazy so be sure to use gloves if you are going to use this method.
Chlorine
Yep, simply mix some clorine and water together and soak your hot tub filters in the solution. This will clean and santize your hot tub filters and it’s inexpensive espeically if you use chlorine in your hot tub already.
