Drip irrigation in organics: trouble shooting

A grower is raising thousands of organic greenhouse herbs
via pot culture and has trouble with clogging in the drip
irrigation system.

Diluted sulfuric acid is used as a clog preventer in drip systems
in standard horticultural production systems that do not adhere
to certified organic standards.

What are some alternatives that would pass for certified organic?

Does anybody have any tips on acceptable vs prohibited, efficacy,
sources, costs, and dilution rates for the following?

Potential substances to un-clog drip irrigation tubes and emitters in
certified organic horticulture production:

* Baking soda
* Acetic acid (vinegar, concentrated)
* Phosphoric acid (food grade, concentrated)
* Hydrogen peroxide (35%, concentrated)

I'll pass on any suggestions. Thanks!
