The Unger Professional Streak-Free EasyGlide Glass Cleaner Concentrate is a highly effective glass cleaning solution. Its standout feature is its impressive concentration level: a 32 oz bottle can make up to 25 gallons of cleaning solution, making it a cost-effective choice for large cleaning tasks. Additionally, the formula is ammonia-free and environmentally friendly, which is safer for skin and surfaces and makes it suitable for those sensitive to strong chemicals.

The cleaner is versatile, as it works on various glass surfaces including windows, mirrors, shower doors, and even car windshields, and is safe for use on tinted windows and LOW-E glass, making it a good fit for household and automotive cleaning tasks. Users will appreciate the streak-free cleaning results that leave no foam, film, or residue behind, ensuring a clear and spotless finish. Being unscented, it’s a good option for those who prefer a fragrance-free cleaning experience.

Mixing and using the cleaner is straightforward, but to achieve optimal results, pairing it with an Unger window scrubber and squeegee (sold separately) is recommended. A potential drawback is the additional purchase of these tools for best results, which may be an extra cost for some users.

Buying Guide for the Best Concentrated Glass Cleaners

Choosing the right concentrated glass cleaner can make a significant difference in the cleanliness and appearance of your windows, mirrors, and other glass surfaces. Concentrated glass cleaners are designed to be diluted with water, offering a cost-effective and efficient way to maintain sparkling clean glass. When selecting a concentrated glass cleaner, it's important to consider several key specifications to ensure you get the best product for your needs.
Concentration LevelThe concentration level of a glass cleaner indicates how much the product needs to be diluted before use. This is important because a higher concentration means you can make more cleaning solution from a single bottle, which can be more economical. Concentration levels can vary, with some cleaners requiring a small amount of product to be mixed with a large amount of water, while others may need a higher ratio of cleaner to water. If you have large areas to clean or want a long-lasting supply, opt for a higher concentration level.
IngredientsThe ingredients in a concentrated glass cleaner determine its effectiveness and safety. Look for cleaners that contain powerful cleaning agents to remove dirt, grime, and streaks without damaging the glass. Some cleaners may include ammonia, which is effective but can be harsh and have a strong odor. Others may use vinegar or alcohol, which are gentler and more environmentally friendly. If you have sensitivities or prefer eco-friendly products, choose a cleaner with natural ingredients.
CompatibilityCompatibility refers to whether the glass cleaner can be used on different types of glass surfaces, such as windows, mirrors, and glass furniture. Some cleaners are formulated specifically for certain types of glass and may not be suitable for others. Ensure the cleaner you choose is versatile and can be used on all the glass surfaces you intend to clean. If you have specialized glass, such as tinted or coated windows, check that the cleaner is safe for those surfaces.
Ease of UseEase of use is an important factor, especially if you plan to use the cleaner frequently. Consider how easy it is to mix the concentrate with water and whether the cleaner comes with clear instructions. Some products may come with a measuring cap or dispenser to make dilution easier. If you prefer convenience, look for a cleaner that simplifies the mixing process and provides straightforward usage guidelines.
EffectivenessEffectiveness is crucial in a glass cleaner, as you want a product that leaves your glass surfaces spotless and streak-free. Read reviews and product descriptions to gauge how well the cleaner performs. Some cleaners may be better at removing tough stains and grime, while others excel at leaving a clear, streak-free finish. If you have heavily soiled glass or want a pristine finish, prioritize effectiveness in your selection.
ScentThe scent of a glass cleaner can impact your cleaning experience. Some cleaners have a strong chemical smell, while others are formulated with pleasant fragrances or are unscented. If you are sensitive to smells or prefer a fresh scent while cleaning, choose a cleaner with a fragrance you enjoy. Unscented options are also available for those who prefer no added scents.
