This question, about cleaning oils and such off of a small stove, was closed by me and 4 others as off-topic. The reason I gave is that operation of appliances is off-topic, and I consider general cleaning to be part of the operation.
@RedGrittyBrick mentioned in the comments the existence of a cleaning tag with almost 400 questions, so he thought it must be on-topic. The tag info provides
For questions relating to the removal of dirt, debris and other unwanted foreign material from various surfaces and porous materials, including methods, tools and supplies, and expected results.
My initial thought about the cleaning tag is that surely it doesn't encompass all cleaning questions, as we don't want to explain basics like how to vacuum a rug or dust shelves. It must be related to questions about how to clean up after home improvement projects - cleaning paint brushes, spilled cement, etc. But, the tag info itself suggests that all cleaning questions are on-topic here.
Am I off-base? Should the tag info / wiki be improved to highlight which types of questions are on- and off-topic?
