The Protocol K-400 is real nice to final mop after using the Protocol K-300. I use the K-300 for problem spots and then rinse with the K-400. I have been washing all my floors with the K-400 and it seems to work very good. I’m just about done the bottle of Eliminator 42, I have found that the quat works great, removes all odours from the washrooms.
