To cleaning plants, any solution strong enough to kill black brush algae will likely damage if not kill the plants. Anubias attracts this algae due to its tough leaves and very slow growth. Keeping it in shade (not under direct tank lights but under another plant or floating plants) can help reduce the chance it will grow brush algae. And that is what your "black algae" likely is; it is actually a red algae, but it looks black to most of us. I have brush algae in most of my tanks; it is controlled by the light intensity/duration, as I think I've explained elsewhere.
The only useful purpose in quarantining plants would be to prevent them from bringing in fish parasites, etc. if they come from tanks with fish. I never do this. Some suggest rinsing them in this or that, but this has limited effectiveness for the same reason mentioned above.
Many aquarium plants are bog or marsh plants, not true aquatics. Those you mention fall into this c category. If you read the profiles you will see references to growing them emersed (out of water). As noted therein, the leaves will usually be different; aquatic leaves and terrestrial leaves have a different function and are thus different in design.
Oh goody, I'll see if I can grow the Anubias emersed. I've got waay too many to keep them all in my current tanks.
