Cleaning a catalytic combustor with vinegar bath

[NHWS]

I don't know enough to agree or disagree, but the MidWest Hearth site seems to say the opposite on some points:

Metal substrate catalytic combustors provide a lower resistance to air flow and require less heat to warm up to operating temperature. The corrugated metal allows chimney smoke to flow through almost 90% of the total front area while still providing more surface area than a ceramic combustor.

Another advantage of a metal substrate is the ability to manufacture the combustor cells with significantly thinner walls allowing more surface area per inch and thus converting more of the smoke into less harmful emissions. ...

• Metal reaches operating temperature faster
• Metal has more surface area for less emissions and more heat
• Metal does not crumble
• Overall service life is the same

The Condar catalytic combustor site says similar things.

It's plausible that either/both sites are just pushing the higher cost product.
