Either spray with your outside hose or let soak!
A filter will last longer if you clean it monthly,however, the older a filter is and the longer you let it sit means the more dirty it is – which will make your water unclear. If your water becomes unclear and dirty, you should start with changing your filter and putting in the correct amount of chemicals before calling for a service check.
Many people spend money and on service checks before cleaning their filter and checking their chemicals. It is very important to stay up to date on your hot tub and pool maintenance to aviod other issues that may occur later on.
