Painted and coated steel
A coating rather than a metal, and the coating decides everything. Strong alkalis attack coatings directly; abrasives and solvents are the other two risks.
What not to do
Mild abrasion may damage Painted and coated steel
Best avoided
The available guidance advises against this.
The technique that is correct on a stove's glass panel is wrong a few centimetres away on its painted body.
Precautions
- Test on an inconspicuous area first

In detail
Most of a wood-burning stove's visible bulk, and a great deal of domestic metalwork besides, is steel carrying a paint or powder-coat finish. The distinction that matters is that the cleaning question is about the coating, not about the steel: whatever the metal underneath tolerates is irrelevant while the paint is intact, and once the paint is gone the appearance cannot be restored by cleaning at all. On alkalis this is not an inference — a US state hazardous substance fact sheet states plainly that sodium hydroxide attacks coatings, alongside iron, copper, plastics and rubber, which is why caustic oven and drain products carry the warnings they do about surrounding surfaces. Two further risks follow from how organic coatings behave generally rather than from any source that names stove paint: stove paint is a thin matt heat-resistant finish that abrasives burnish or remove, and solvents including alcohols can soften or lift organic coatings. This is the clearest case of why an object-level answer is dangerous — the technique that is correct on a stove's glass panel is wrong a few centimetres away on its painted body.
