I love using FZ150, it revitalizes color and actually is safe on all products. I use it on my designer shoes. Great product !
This stuff work great . Not sure what’s in it but it works. Like any hard working person knows, the more you put into it the more you get from it . If the shoes are slightly dirty, a light cleaning is all that’s required. The harder you are on your shoes, the harder you’ll have to clean , but it will be worth it.
