What is a good acid based cleaner to clean pool filters?

Question

We have an above ground doughboy pools with a pump. (You can buy at any Wal-mart) We have been reusing the filters that go in the pump but they haven't been getting as clean enough. We found on line where these can be cleaned using an acid based cleaner, but what? Need something affordable so we can keep reusing filters. (Wal-mart ALWAYS sells out) Only serious answers please.

Answer 1

Any brand of white vinegar (which is  acid based and also used in a lot of health centers as a cleaner ) is very cheap and readily available, soak over night and rinse thoroughly.  I don't think ammonia is a good idea.  Good luck.

Answer 2

ammonia like the person above said you can just take a pee in it and thats ammonia for you.  In other words ammonia is pee.  Buy some lemons so your going all organic and squeeze the juice into the filter.  The juice is high in citric acid.

Answer 3

I have worked at a pool store for 3 years now. We sell a product called Muratic Acid.  You would soak your filter in a solution of 3 parts acid to one part water for no more than 5 min. You can do this as often as you need to. Also when you squirt your filter down with the hose, never spray from the outside in. Always spray from the inside to push all particles to the outside.

Answer 4

ammonia!

Answer 5

pool acid...that they use for plaster pools to lower PH...let them soak overnight
