Thus, 2.5 fluid ounces of the cleaning solution is made of 2 fluid ounces of alcohol (.5 fl. For example, if you want to make 2.5 fluid ounces of the cleaning solution, then divide 2.5 by 5 to get.

Next, divide the total desired amount by the whole count to get the amount for each part. The formula above (4+1) happens to be 5 parts. Warning: this rest of this paragraph contains MATH instructions. First, add all parts together to get a whole count, which is the number of parts that make a whole. If “parts” in a formula confuse you, don’t worry (unless you hate math). And, municipal (“city”) water usually also contains chlorine, an oxidizing agent which will damage the print-head thru corrosion. Mineral and unfiltered water both promote clogging. However, if you do this, only use de-ionized filtered water. The source video also provides a formula to replace Windex with ammonia and water. Using Windex with additives or cheaper brands might create more problems than it solves. Importance of Water Quality in this Solution The video from which this formula was derived is linked below.

4 parts alcohol (isopropyl) + 1 part Windex.
