How to Clean Bioethanol Fireplace Glass

Short answer: The haze on a bioethanol fire screen is a thin film of combustion byproduct condensing on cool glass, not soot. It comes off with warm water and a little mild soap for routine cleaning, or a vinegar wipe for a heavier film. Let the screen cool for at least two hours first, work it in one direction then a second pass to finish streak-free, and skip anything abrasive.

None of My Acre's EcoSmart fire pits or fire tables incorporate a glass front as standard. The glass belongs to the six Fire Screens sold as accessories, tempered-glass wind guards that position over the burner flame rather than fully enclosing it. If you're picturing a sealed glass box like a gas fireplace, a bioethanol burner doesn't operate that way: the flame stays open to the air; the screen's job is to stabilise it in a breeze, not contain it.

What the haze actually is

A cloudy film on the inside of a fire screen is condensed combustion byproduct, not the black soot a wood fire leaves behind. It is a residue problem, not a dirt problem. Bioethanol burns close to clean, but no burn is perfect. The film that does form settles on the coolest surface nearby: the glass itself, rather than the surrounding stainless steel components.

EcoSmart's own burner guidance describes the same accumulation on the metal. Clean the burner after approximately 50 litres of fuel, or as soon as black deposits appear near the opening, using hot soapy water followed by a stainless wipe finished in the direction of the grain. The screen collects the same kind of residue on a considerably slower schedule, simply because it sits further from the flame.

The actual cleaning method

Let the screen cool for at least two hours before touching it; glass retains heat considerably longer than the stainless around it. For routine cleaning, warm water with a small quantity of mild dish soap typically lifts most of the film, wiped with a soft cloth rather than anything textured. For a heavier haze, a vinegar-and-water solution or a proper glass cleaner cuts through it effectively without touching the finish. One bioethanol fireplace maker's own care guidance recommends exactly this approach: a non-scratch pad with warm water and a little washing-up liquid, never anything abrasive on the glass itself.

Dry it in one direction, then a second, lighter pass to eliminate streaking. A quick wipe after each use keeps the film from accumulating; a proper clean once a week under regular use stops it becoming a job.

The honest verdict

If the glass looks hazy, it's doing exactly what bioethanol glass does. Clean it cool, clean it mild, and skip the abrasive pad your instinct reaches for.
