There are number of ways to clean a Jacuzzi Hot Tub (בריכות ספא) 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.
I would recommend using any of the following methods for cleaning your hot tub filters.
Muratic Acid: This is the old fashioned way of cleaning spa 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.
Chlorine: Simply mix some chlorine and water together and soak your spa filters in the solution. This will clean and sanitize your Jacuzzi Hot Tub (ג׳קוזי) filters and it’s inexpensive especially if you use chlorine in your hot tub already.
Spa 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 Jacuzzi Hot Tub (בריכות ספא) filters and let them sit for about 15 minutes or so and hose them down with water.
