Lyman Turbo Brite brass polish smell

Never used this or anything similar but wanted to see if it does anything to my walnut.....

The new sealed bottle has some crusty stuff around the neck - looks like a discolored spot in this pic, but a little caked on buildup. But when I opened the bottle and removed the seal, I noticed right away it smells like sour milk. Not as strong as a gallon of spoiled milk, but definitely a similar smell, just not as strong.

Didn't seem right so figured I's ask before ruining a bunch of media with it. For some reason I expected it would be more like a fluid - about consistency of maple syrup is what I was expecting, but this is more like hand lotion or thicker. I can remove cap, turn bottle upside down, & it doesn't flow out. So should it be that thickness and have that odd smell or should I exchange for new bottle?

I've used it for years, along with Brasso, and Car Wax. Turbo Brite works very well, just add about a tablespoon to the Walnut Media, let it run about 15-20 minutes, then add the brass.

Good Luck
