OPT 20529 32 oz. Optimum Carpet/Fabric Cleaner/Protectant, 32 fl. oz, 1 Pack

Maybe I got some from a bad batch? I diluted 1:3 as recommended in a sprayer and it smelled like ammonia while applying. I cleaned it up as best I could but the smell lingered for a couple of days. Looking at the bottle now I noticed that the stuff has separated. Shaking the bottle recombines it a bit but there are little flakes floating around inside. No reviews of the product mention the terrible smell so there must be something wrong with my bottle.

I have used Optimum Carpet/Fabric Cleaner now on many different spots in cars and on regular carpets and I have managed to remove a lot of spots. It doesn't work like magic and remove any spot that one encounters, but it is pretty close to magic. Compared to many general spot cleaners out there this is one that works really, really, well.
