Glass Wizard Review

Glass Wizard
Bottom Line

The Glass Wizard is a tool for cleaning glass that has a swiveling, wedge-shaped, flexible foam head for getting into corners. The head is designed to be covered with one of the two machine-washable, reversible bonnets provided. A mesh "grime-buster bonnet" -- intended for heavy-duty cleaning -- is also included, along with a spray bottle that you can fill with either water or glass cleaner. The handle is about 18 inches long, and it's covered with soft foam for comfort. You can use it with a standard extension handle for a longer reach. The contraption is similar to the Windshield Wonder, another as-seen-on-TV cleaning tool.

Reviews are mixed when it comes to whether or not the Glass Wizard cleans better than -- or even as well as -- a regular cleaning solution plus rags or paper towels. Reviewers agree, though, that attaching a cover to the head is a tricky, tedious process. Two reviewers also note that it can be hard to apply pressure except right where the handle backs the pivoting head.

  • Reaches tight places
  • Reusable, reversible covers are machine-washable
  • Comes with mesh cover for sticky debris
  • Can attach to threaded extension handle
  • Tedious to attach cover
  • Uneven pressure across surface of head
  • Doesn't fit curved windshields well
  • May leave streaks

Reviewers do like the way the Glass Wizard reaches into tight places, and using it with an extension handle makes cleaning hard-to-reach windows easier. If you have trouble reaching or bending, the 18-inch handle might make the Glass Wizard a worthwhile buy.

We found the most recent video review of the Glass Wizard at, which rates it after trying it on a bathroom mirror and on a sliding-glass door. Several TV stations put the Glass Wizard to the test. An enthusiastic review at KLTV (Tyler, Tex.) is the most recent, but WTXF (Philadelphia) provides a more balanced review with specific pros and cons. The Glass Wizard gets much lower grades in two tests at news stations WBAL (Baltimore) and WFVS (Cape Girardeau, Mo.). The review at seems critical but fair, while a handful of owners give the Glass Wizard mixed reviews at

Glass Wizard Review, "Dan", Nov. 29, 2009

This detailed video review posted on YouTube tests the Glass Wizard on a bathroom mirror and a sliding-glass door, using a regular glass-cleaning spray. The results are streak-free, but the main advantage is the ease of cleaning along edges, in tight places and in corners -- without much stretching or bending. The reviewer gives the Glass Wizard 4 stars out of a possible 6; it loses points because the bonnet is so hard to attach, and because it doesn't seem to clean any better than other products, just faster.

Glass Wizard: "Does It Work?", Joe Terrell, Feb 2, 2005, updated April 7, 2009

Tests here confirm that the Glass Wizard does everything that it claims to. The grime-buster cover removes sticky candy and handprints well; then the microfiber cover finishes the cleaning job. Reviewer Joe Terrell says the head is easy to maneuver on glass and reaches corners well, even on windshields.

Deal or Dud: Glass Wizard, Michelle Buckman

This three-minute video shows tests of the Glass Wizard (with plain water on the microfiber bonnet) on car windows, including the inside of a windshield, as well as on a large indoor office window. The tester judges it a good deal for occasional use, since it minimizes streaks and reaches well. However, he finds the cover hard to attach, and criticizes the way it's hard to apply pressure to edges, saying, "There's only pressure where the handle connects."

Does It Work? Windows, Meet Glass Wizard, Lisa Robinson, Feb. 9, 2005

The Glass Wizard gets a thumbs-down with an overall grade of D, because tester Lisa Robinson has poor results when using it to clean the outside of her front door window. After using the mesh bonnet first and then the microfiber bonnet, it still leaves streaks and spots. Furthermore, she concludes that using the Glass Wizard takes more effort than using a paper towel and glass cleaner. The video review has been taken off the WBAL site, and it's not clear from the text whether or not Robinson used water or a glass cleaner with the Glass Wizard.

Glass Wizard, Amy Jacquin, Sept. 22, 2004

Reporter Amy Jacquin gives the Glass Wizard a grade of C-plus after testing it on a car windshield. She has a lot of trouble getting the bonnet on, then finds that the flat head on the Glass Wizard doesn't clean the curved windshield well. Jacquin has to use her hands to press down on the head itself, rather than holding it by the handle.


Review: Glass Wizard, Editors of

This brief review notes that a rag and some glass cleaner works just as well as the Glass Wizard. However, the Glass Wizard might be worth buying for use with an extension handle if you have windows that are hard to reach.

The Glass Wizard gets mixed reviews from the handful of owners rating it. One owner says it's great for cleaning high windows, but adds that the handle threads are flimsy and easily stripped when screwing it onto an extension handle. It's also tricky to get the bonnets attached unless they're wet first. Another owner says washing the covers with fabric softener ruins them, and they'll smudge glass afterward.
