Does anyone have a home brew that's as good as any store bought type?

On tractor I use plain old vinegar. Drain the coolant out and fill with vinegar and run it till good and warm. Let cool for a while then drain it by way of the block drain and then back flush with a garden hose at the block drain. May take a couple of flushing but it has always worked for me

Whatever you use, be careful, especially with the phosphoric acid or any of the commercial products.
If the engine has freeze plugs, or the radiator is getting thin, it may start some leaks, or renew some previous leaks that had clogged with sediment, including head gasket leaks.
Also be sure to flush it thoroughly with the engine running at fast idle. If it has a thermostat, it will need some way for the water pump to flush around the thermostat, as in removing a heater hose, a bypass hose, or removing the thermostat. Otherwise the cold water from the garden hose will close the thermostat and leave uncirculated water and treatment in the block. If the block drain plug will come out, and you can get the passage open, all the better.

Like I said in your other radiator post, if it's all metal, try muriatic acid. Just be careful and soak the radiator out of the vehicle. Dont let it sit longer than 15 min and be sure to neutralize the acid when you are done.
