Blue Magic Carpet Stain & Spot Lifter 22 Oz. (pack 2)

Some of the reviews complained about the spray nozzles were broken rendering the cleaner unusable. Can I get a refund if that happens?

I want the 2 pack but it doesn't say 2 pack in the cart.... Will I get 2?

will it remove mustard stains?

Does this product use carbonation to lift the stains? I use a much more expensive carbonated brand that works well, but would rather pay less.
