Find or purchase a gallon plastic bottle for mixing and storage. You need a clean bottle, not previously used for commercial chemicals. Empty water jugs work well. You will also need a clean sprayer bottle. I prefer heavy duty sprayers.
Pour the isopropyl alcohol and ammonia into the mixing container.
Fill the remainder of the gallon mixing container with water.
Place the dish soap into the top of the container, recap, and invert gently to mix the ingredients.
One thoroughly mixed, fill the sprayer bottle, and use on your glass surfaces.
