1 L (33.8 fl. oz.) Safe, ammonia-free shine Leaving your glass surfaces with a smudge-free, spotless shine usually means using an ammonia-based cleaner. Not the case with this spray. When mixed with water, it eliminates dirt, dust and fingerprints with a single swipe – and without the chemical odor. Streak-free and leaves no harmful residue. The 1 L bottle will refill the 500 mL (16.9 oz.) spray bottle 8 times! Now that’s a great value.
