When using chemicals, protect yourself. Put on latex gloves, as well as goggles to protect your eyes. In addition, only clean the cell where there's plenty of ventilation, as the acid can produce fumes. Coveralls also wouldn't hurt. At the very least, cover your arms and legs. You use muratic acid to clean the deposits off the filters in the salt cell. However, you must dilute it because straight muratic acid is too strong. Pour water in a clean bucket that's easy to pour from. Add muratic acid to the bucket.  Start with five parts water to one part acid. Never add water to acid. Always add the acid to the water. While occasional cleaning of a cell is acceptable it’s best to only do so when required. While the acid does remove any Scale it also damages the plates inside of the cell itself thus reducing the life. The easiest way for the solution to reach the filters is to simply pour it into the cell. To do that, screw the cell into the cleaning stand, which caps off one end. The stand goes on the end where the cord is. Stand it up on that end. Using the bucket, carefully add the solution to the salt cell, making sure not to spill it on yourself. It should cover the filters inside, coming most of the way up the inside of the cell. Leave the solution to soak for 10 to 15 minutes. The mixture will foam up inside the cell. That is a good sign, as it means it's working on the mineral deposits. Once the mixture has stopped foaming, that usually means it's clean, though sometimes you may need to go through the process again. For the moment, pour the solution back into the bucket. Once the deposits are gone, use the garden hose again. Thoroughly rinse out the inside of the cell, as chlorine and muratic acid shouldn't mix. Once you're sure it's thoroughly cleaned out, the process is done. Put the salt cell back into position; it doesn't matter which direction it goes on most units. Screw the unions back in place. Plug the unit back into the wall, and clear the inspection light on the control panel by holding down the up arrow or pressing down the diagnostic button for three seconds. You can keep the water-acid mixture in a clean bottle, though you should get rid of it by the time it suggests on the original bottle of acid. To dispose of it, look for hazardous waste disposal collection centers in your area, as that's the best way to get rid of it.
