The Stone & Tile Restoration Manual, presented by Fred Hueston’s Stone Detective, is an online knowledge resource for stone and tile restoration professionals and others interested in the field. Drawing on decades of experience, it provides free access to practical guidance, technical reference material, and training resources. Users can create a free login to explore the manual’s interactive online documents or print PDF chapters to build a personal reference binder; registered users are notified when new material is added.

The manual covers a broad range of topics, including geology and stone identification, quarrying and fabrication, cleaning chemistry, stain management, stone restoration, and sealing and protection. Its resources include how-to instructions, reference charts, sample contracts, and editable forms. The guidance addresses identifying stone, understanding cleaning products, treating different stains, and choosing restoration and sealing approaches for materials such as granite, marble, and limestone. The site also offers articles, a glossary, a natural stone database, a stain management app, professional learning resources, a radio show, and an events calendar.
