That seems to be impossible. If, it loosens the dirt and the mold, it has to go somewhere.
I've used muriatic acid on my cement. Far more dangerous to handle. Time to do it again,
I think I will, I should give it a try.

30-second cleaner is highly concentrated bleach. That's why it works so well. You should use THICK gloves that go up to your elbows if you plan on applying it with a sponge. You should also wear safety glasses, and not wear anything that you care about color with - any cloth it lands on will turn white.
