Hi fellow mastiff owners! We all have the same on-going problem-drool that ends up in the weirdest places. Of course it is easy to wipe it off, but if you don't do it right away, I find it turns into yellow waxy substance that is not easy to clean off. My laminate floors and walls are covered in these spots. Of course I can use elbow grease and a brush to get them off, but it takes a lot of time and effort. I was wondering if there is something else I can do, like a spray and wipe type of product, home-made or commercially produced.
