Initially we were sceptical to the appropriateness of this cleaner around bodywork, and that of the absence of anti-glare properties in its description. Multi-surface cleaners can be naturally a little vague in their descriptions, only to find a list of materials that are unsuited to the harsh solvents contained in the formula squirred away in the small print. However, Simoniz Clear Vision Glass Cleaner does indeed provide a rapid cleaner that lifted the grease away from our test panel and required less buffing than two of our less performing cleaners. The pane was left with no obvious smears, and definitely no smears as heavy as the Tesco Glass and Insect Cleaner and at first appeared to provide a crystal clear finish. However internally we found outside lighting would glare through the thin film of remaining grease that would require extra buffing and a second application to remove. The performance and overall value [per millilitre] of the Simoniz glass cleaner ranks average amongst the brands we tested, but unfortunately, as a complete package failed to deliver a class leading performance. While it may be marketed as welcome inside the household as well as your car, it is typical of that of a multi-surface cleaner, a jack of all trades but master of none. It was outshone by the ease of Meguiar's Perfect Clarity Glass Cleaner ability to lift grime and lubricate, and required extra buffing to prevent hazing of the dry, albeit streak free, windscreen.  

Overall, the Simoniz Clear Vision Glass Cleaner would utilise well as a refill or backup glass cleaner of a better performing brand, as while the solvent formula performs as expected, it is let down by its spray mechanism. Unfortunately when inverted, the nozzle did leak during our storage and shake test, and in fact, is the weakest made of the spray mechanisms we have tested, and would continue to dribble once vertical. It is for this reason that it falls short of a FritzReview Value Award.
