To make a safe homemade window cleaner, combine 1 tablespoon of vinegar to one quart of warm water. Pour the solution into a reusable spray bottle, and you have the safest, best window cleaner for your home. To prevent streaking, do not clean your windows while the sun is on them and use crumpled newspaper to wipe them dry. The newspaper can still be recycled after cleaning your windows.  You may need to add about a “pump” of a good liquid detergent to the mix for your first batch to help remove some of the wax left by previous commercial cleaners.

You can use regular vinegar, of if it is in your budget, give organic vinegar a try. Since you are using such a small amount of vinegar, a bottle should last you a long time.
