Nice product and it’s much like most, spray on, let soak and blotch up. I found that Drainbo had no odor to speak of like most that cover the odor with a fragrance. I trie it on two spots, one was fresh and the other some weeks old and both cleaned up very well lifting the discoloration. They list a few ways to use the Drainbo, from direct spraying to using 2 oz/gal in your carpet cleaner. I like the fact that the cleaner continues to eliminate odor well after your done wiping up the stain with its active enzymes.
I have the fall home carpet cleaning coming up and I plan to pretreat the traffic areas and spots with Drainbo and well as mixing it in.
