(MaryKay,I still use the vinegar, hot water and brown paper bags for cleaning my windows - stops the streaking on the windows - and inside needs.)

I got a bag of dog food from Chewy and it contained a long length of their brown packing paper*Ü*. I tore/cut it into smaller pieces and just used some with the vinegar to do a couple windows. WOW-that combination really does work and now I can get rid of the bottles of window cleaner and just use your method.
Thank you so much for letting us know about this.

So glad you liked it. Grandma would also be glad you enjoyed having a great 'new' and safe product. Costs less as well.
