Hardwood & Laminate Floor Cleanr - 64oz Refill - 2 Pack

selling "2 pack" and pic shows one of the bottles as 64 oz, so clarify......are you selling 64 oz or 128 oz? the detailed description says 64 oz!

How is this different than the green bottle?

How do you use this cleaner? With any regular soft mop? Or do you need to purchase a special mop for this cleaner? Thanks!

Does this product leave a "shine" on the floor?
