I used “Top Purple” for years. i used to have to clean my glasses 3-4 x/day, now it’s barely once a week.
A while back, I received a little jar of “Bright-Now” ..... it sat unused until I had to clean an antique vase w/ a a large intricate large silver fluted top. My only disappointment is that I can’t submit a photo. This is the first time I used BRIGHT-NOW”. All I can say is that it should be called bright-WOW” !
