I purchased this product at The Container Store and it really just doesn't work for OLED monitors with glossy coatings, such as the Dell AW2725DF. I follow the packaging directions of spraying the cleaner on the provided orange cleaning cloth and using it on the monitor, but it ends up leaving aggressive streaks. Only after I polish vigorously with a higher-quality microfiber cloth can I get the streaks to go away, but this is a really time and labor intensive process. The product works better on my iPhone, so maybe it's just the coating on this particular monitor that doesn't work, but frankly, it's not some miracle product for other screens either. I'd probably just save your money and buy some distilled water and high-quality or automotive-grade microfiber cloths -- it'll be cheaper and more reusable.
