Its strong cleaning power effectively removes dirt, smudges, and fingerprints, making it suitable for various glass surfaces like windows, glass stovetops, and shower doors.

Safety for glass surfaces is well-regarded, maintaining the integrity of your glass items without causing any damage.

The product's ease of use is notable, as it comes in a liquid form that is easy to apply and spread across surfaces. However, it is worth mentioning that while this is a refill bottle, you will need a spray bottle to transfer and use the cleaner efficiently. One of the standout features is its environmental impact; Windex's commitment to sustainability is evident with the bottle made from 100% recycled plastic, particularly recovered coastal plastic. This not only helps reduce waste but also supports efforts to protect our oceans.

The cleaner has an original blue scent, which is generally pleasant, but some users might prefer an unscented option if they are sensitive to fragrances. In summary, the Windex Refill Glass and Window Cleaner is effective, safe for your glass surfaces, and environmentally conscious, though the necessity of a separate spray bottle and the presence of a scent might be points to consider.
