cartridge cleaning

[apex]

What are some of the tricks you pros have used for cleaning the cartridges? In the past I have just used a high pressure spray but I am looking for something more efficient or effective.

This might be of some help.

Use care when spraying water on the cartridge filters. You don't want to get too aggressive or you might damage the filter membrane.

"use care" means regular garden hose, don't use a pressure washer.

Thanks all. I have used the garden hose for the spraying, nothing higher.

The acid idea listed in the other post was interesting but would use lots of acid.
