Great Value Clear Ammonia All Purpose Cleaners, 64 fl oz

Clear ammonia is a game-changer for laundry! I use it in my washing machine to brighten whites and tackle yellowing, and it really delivers. Clothes come out looking fresher and more vibrant without harsh bleach. It's easy to use, effective, and a must-have for anyone who wants their whites to truly shine. Whitens and brightens: Ammonia is alkaline, so it can help break down certain residues and soils that make fabrics look dull, giving the appearance of brighter whites. Removes yellowing: It can help lift body oils, sweat, and mild discoloration from fabrics, which are common causes of yellowing. It's most effective when combined with a hot wash or a small amount of detergent. Limitations: It won't work on all stains, especially deep-set rust, bleach damage, or very old yellowing. Also, it's important not to mix it with bleach or other cleaners, because that can create dangerous fumes.

How do you get ammonia wrong? There is no realistic way to test for full strength. You just use it. It looks and smells like ammonia. It cleans like ammonia. It is priced really well. The 1/2 gal is a convenient size to keep under the sink, so I always keep some on hand for those occasional situations where I want to use it. It's just basic ammonia.
