The acid you use to clean the filter can be dangerous, especially before it is diluted. If you don't use proper protective equipment it can burn your skin and the fumes can damage your lungs. Before using it, put on gloves that are made for dealing with chemicals. Also put on a respirator and eye protection, so that if the acid splashes it won't get in your eyes. Muriatic acid is similar to hydrochloric acid. It can dissolve many plastics and metals, as well as skin. This mixture is used to dissolve minerals that accumulate in the filter media. Use another clean bucket with a lid that seals tightly. Add about 2/3 of a bucket of clean water, then carefully pour in enough muriatic acid to give you a 1 part acid to 20 parts water solution. In a typical 5 gallon bucket, this means about 6 gallons of water to 1 1/2 quarts acid. Using a 5% muriatic acid solution to remove calcium deposited in the filter media will increase the filter's performance if high concentrations of minerals exist in your pool water. Too many minerals in the filter reduces the rate that water can pass through the filter. This makes the filtration system work harder than it should have to. The bubbles are an indication the acid is reacting with the mineral deposits, and when the bubbling has quit, the minerals should be dissolved. This usually takes about 10 minutes. Use plenty of fresh water to remove all of the minerals that have been loosened by the acid. Once they are clean, allow them to dry before putting them back in your filtration system. Shake any remaining collected dirt from the pleats, and they are ready either to proceed to chlorine soaking, or if this step has followed the chlorine soaking, they are ready for reuse in your pool. If you keep your container sealed tightly, the acid will not weaken. This means it may be reused repeatedly for filter cleanings. Store the container in an out of the way place where there is no chance of it getting knocked over or opened by a child. . Allowing the containers to remain open will allow the water to evaporate out of your solution, rendering it overly strong in a short time.

One-sentence summary -- Put on personal protective equipment before using muriatic acid. Mix a solution of muriatic acid and water. Soak the filters in the acid solution until it quits bubbling. Spray the acid-cleaned filters with a hose. Seal the acid container when you are finished with it.
