Water Is Key
Don’t just use any old tap. You need to make sure that you need to have water that is not hard. Hard water will cause problems with spotting and issues. Make sure that you focus on softer options, or even deionized solution. The wrong water will absolutely change the complexion of your output, so don’t just go with tap water if you have hard water in the pipes, simple as that. If you have a filtered solution, go that route.
Adding To The Water
Water is the first thing, but the next thing that you need to look into is adding a little bit of dish washing solution. Use n more than 2 teaspoons. This is very important, do not use a lot, you don’t want a lot of suds, and you don’t want residue. You’re going to have to use very little here. You can add vinegar to your solution and get a little more cleaning power, specifically with windows. Just make sure that you are not allowing the solution to settle on rubber or vinyl gaskets that could cause leaks in your window frames. Make sure that you use a gliding squeegee or you’re not going to get a clean window. You want this to be absolutely slick, and made for windows.
Simply put, the above should suffice to help you get cleaner windows without hiring someone, or having to buy heavy chemicals. You’ll want to use a good dispenser for the mixture that you’re going to make. One option is to look into a gallon jug that you can mix your window cleaning solution and then pour it into a spray bottle. Test this out on a simple window, and wipe it down to a clean, clear solution. It’ll be easier than you think.
