Source hierarchy
Primary regulatory or product-specific material is preferred where it answers the question. High-authority technical and established cleaning references are used for fiber behavior, stain processes and practical context.
How sources are used
A source being listed does not mean every statement on the site comes from that source. Content-source links and claim records are used to connect references to the pages and structured guidance they support.
