These are the rules we hold ourselves to. They exist because most of what gets published about commercial and industrial cleaning is either advertising or copied from other advertising.
Numbers
Every cost figure is a range, tied to a scope of work, and reflects recent field practice rather than a national average. Technical figures — dilution ratios, dwell times, PSI ranges, cure windows — are given where they change a decision and are checked against manufacturer and agency guidance rather than repeated from other articles.
Where a number is genuinely uncertain, we say so. Where a range is wide, the article explains what moves it.
Sources
Technical references point at primary material: OSHA, EPA, NIOSH, NFPA, and standards or research bodies. We do not cite marketing pages, lead-generation directories, or aggregators.
Corrections
Articles are revised when something in them turns out to be wrong or out of date, and the substance of the correction is reflected in the text rather than buried in a footnote. Nothing on the site is written to a deadline that would justify publishing something we are not confident in.
Independence
No article is sponsored, and no placement in an article is for sale. Where an article mentions a category of specialist contractor, that reflects who normally does that adjacent class of work, and no arrangement exists behind it.
Scope
We write about cleaning, maintenance, and the safety and compliance work around it. We do not cover residential housekeeping, retail janitorial franchising, or anything where we have no direct working experience. When a subject sits outside what the contributors actually know, we leave it alone.
