What's the proper way to use the glass cleaner concentrate? Using a terry towel, or a microfiber? I've got some stubborn streaks that just won't come off, and figure a concentrated formula may be just what I need.
Also, what is the proper way to apply #40? Do you need to spay it on, and then buff it out, or how do I use it? Also, I've got some residue left from my last interior protectant, and it's quite shiney, how would I remove this before applying #40?
Thanks.
