Dump all the ingredients into the amber bottle as previously described. Shake it to dissolve it a bit. The little daro chunks won't dissolve super-easily though. Close it, put it in the microwave and run it for 4-7 seconds at a time to heat it up to warm but not burning hot temperature (should still be able to hold the bottle). Shake it for five minutes. Once it's cooled down, reheat again for a few seconds and shake again. Repeat a few times and it should 90% dissolve. At that point it's usable. The last little bit will sit at the bottom and dissolve by the next morning just sitting on the counter.
Mild nuissance but worth it for hair.
Also someone said earlier in the thread that they were putting their bottle of daro in boiling water to dissolve it. I wouldn't recommend it. We only know enza is stable up to 80 degrees. We don't know how stable daro is. Boiling water is 100 degrees C and this may be too much. Like I said, I try to keep it comfortable to the touch, which should definitely be less than 80 degrees C. If it's too hot to touch, back off a bit on the heating. No need to blast it so hard.
Lastly, I never bought one, but I mentioned earlier in the thread there are also mini paint shakers for hobbyists that would work well to dissolve this sort of thing. Not sure if that would avoid the need for heating.

I'm happy with the current method and can't be bothered at present.
