I've seen it recommended to clean your drip irrigation tubing periodically with an acid solution. However everything I've seen seems to relate to large-scale systems with pumps and reservoirs with which you can mix in the acid.

I have a small system running off a hose from my household faucet and I'm looking for a good convenient way to apply an acid solution. I'm thinking about those sprayers you can get with a little reservoir. You screw them onto your hose and spray a solution. Something like that would be good, but it would have to have an outlet that would take a hose fitting (which is on the inlet to my irrigation system). I haven't been able to find anything like that. Does anyone have any suggestions for this?
