Window Cleaner Recipe

Question: A friend of mine recently inquired of me, what is a good cleaner for his windows without paying a fortune for those little commercial spray bottles of glass cleaner?

Answer: After asking my friend this obvious question first, “Why in the world are you cleaning your windows in the middle of winter?” I was sure to advise him not to use hot water on cold glass during the winter! I then stated this to him, “I’ve met up with many other contractors in the course of my business, including professional commercial and residential window cleaners. I’ve asked each of them a similar version of this same question.” Most common answer is this following recipe:

Window Cleaner Recipe

Take one bucket that your squeegee will fit into, at least two to four gallons in size to contain the mix. Using two gallons of hot water (medium-hot to the touch is sufficient) and to this add one tablespoon of trisodium phosphate (T.S.P.) and mix until completely dissolved. I like the spoonable TSP, but I see there are liquid versions available also now. Add two tablespoons of household white vinegar and mix again. That’s it! You’re now ready to get to work.

Trisodium Phosphate (T.S.P.) can readily be found at your local hardware store. They also have a bio-friendly version of T.S.P. out now but I haven’t tried this in the window cleaner recipe as of yet. So be sure to let me know if any of you have. As to the vinegar, that can be purchase at your local grocery store. Be sure not to include too much TSP in your recipe or you will need to rinse your windows, paint, landscaping and so on afterwards. This will also remove the vinegar which is there to make the windows shine after squeegeeing them off.

Hope this helps everyone. Any of you with good luck with another recipe, please add it in the comment box and I’ll post it too!  Thanks, all!

  2. You’re right, Garden Landscaping! Just be sure that you use a gentle spray and not high pressure as that can also remove loose or faulty caulking , not to mention get under the siding and cause problems there. Thanks for the comment! SparkChaser4.
