How We Research and Fact-Check Every Guide

Detail-It-Yourself publishes researched guides to car care and related equipment. We use product instructions, manuals, technical documents, research, and clearly attributed secondary reporting to explain practical decisions. These guides are not a substitute for inspecting your vehicle or following its manufacturer’s instructions.

Who writes the guides?

Jordan Reyes is our editorial pen name, not a detailing credential or a separately identifiable reviewer. An editor develops the guides with AI assistance and is responsible for the published copy. We do not have a certified-detailer review board, and we do not claim to have personally tested a product merely because it appears in a guide.

How we use evidence

We prioritize the document closest to the claim: a product label for dilution, an owner’s manual for vehicle care, a regulator for its requirements, and a research paper for its results. We also use shop price lists, specialist reporting, and owner discussions when they add useful context. Those sources have different limits:

• A manufacturer’s durability claim is not an independent long-term test.
• One shop’s quote is not a national price average.
• An owner’s experience can reveal a question worth investigating, but it does not establish a universal result.
• A formula or planning estimate needs its assumptions stated, particularly when the result depends on your use or local prices.

Links should support the claim beside them. When a source is archived, limited, or anecdotal, that limitation belongs in the explanation. Retrieval tools, research commands, and internal drafting notes do not help readers assess a claim and are kept out of the public copy.

What our images show

Guides include licensed photographs, product imagery, and explanatory illustrations where available. A photograph of a product does not prove performance, and an illustration does not document a hands-on test. Captions and credits identify the image’s purpose and source. The driveway-wash guide, for example, uses a diagram to explain the two-bucket process.

Product recommendations and affiliate links

Some links earn us a commission if you buy. The relevant link or page identifies that relationship. Access to partner catalogs influences which products we can link commercially; it does not justify recommending an unsuitable product. A guide may have no recommendation at all.

Product prices, ratings, stock, and promotions change. A dated example is a snapshot; check the destination listing before purchasing. We do not represent catalog specifications as independent product testing. See our Disclaimer for the commercial disclosure.

Corrections and updates

Sources and instructions change, and published guides can contain errors. We correct substantive errors, update the affected explanation and dates, and add a visible correction when the earlier conclusion materially changes. For example, the PPF waxing guide now identifies the applicable 3M document revision instead of treating older wording as current.

If you spot a problem, use the contact listed in our Privacy Policy and include the guide URL, the sentence at issue, and a supporting source if available.

Before using a guide on your car

Check the manual for your model, the label and safety data sheet for the exact product, and the condition of the surface. A general comparison cannot resolve an unknown finish, damaged component, chemical exposure, or safety-critical repair. Get a qualified professional’s assessment where the task requires one.
