Unlike mass-imported rocket stoves, the MASHWI^MC is hand-welded in Québec from thick Canadian steel, not thin sheet metal that warps after a single season. It gets an exclusive food-grade grapeseed-oil seasoning, cured with heat into a dark patina: a tough, durable finish. Its L-shaped chamber is designed for the Canadian climate, from −20 °C to humid summers. And if a problem comes up, you talk to a team from here, not a service abroad.

An outdoor cooking appliance with an optimized burn: a safe, L-shaped firebox that burns wood very efficiently. Intense heat, little fuel, almost no smoke with dry wood, and no propane or electricity.

Yes, the MASHWI^MC complements or replaces a propane barbecue, depending on what you need. Its real strength: authentic wood fire, for grilling, mechouis and camp meals, with the family, on a fishing trip, at the hunting camp or at big gatherings. And it lights a live flame in under two minutes, where wood has always had a reputation for being slow.

An outdoor cooking appliance like the MASHWI^MC is not an open fire, and many municipalities treat it differently. Rules do vary from one municipality to the next and with the forest fire danger level. Check your municipality’s bylaws and SOPFEU notices before lighting.

Once the rocket stove has cooled completely, empty the ashes, wipe it dry and store it folded, out of the rain. Every 4 or 5 uses, renew the patina (see the question about oil).

Carbon steel exposed to heat, cold and humidity can develop light surface rust: that’s the very nature of steel. The oil patina helps resist this surface rust and extend the life of the rocket stove, without being a permanent protection. Stored dry and maintained regularly, your MASHWI^MC will stay with you for years.

Every rocket stove is abrasive-blasted and cleaned in Québec, then seasoned with a very thin layer of food-grade grapeseed oil, cured with heat. Heat and air polymerize the oil: it forms a dark, bonded patina that adheres to the prepared steel. Unlike paint, which dulls in the fire and needs touch-ups, this patina renews at home, in a few minutes, with a food-grade oil. A natural, eco-responsible finish, prepared here.

Use a few drops of food-grade oil, grapeseed or canola, on the accessible outer surfaces, clean and cold, then wipe off all the excess. Wait until the next day before lighting again. Avoid: oiling a rocket stove that’s still hot, the fuel feed or the cooking surface right before lighting. Too much oil leaves runs, a sticky surface and smoke.
