Returning a new LP for a replacement will do no good if the film on the LP was there when it left the factory: the replacement copy will most likely be exactly the same.
One of the Last Factory products is named "Power Cleaner", and it was formulated for first time LP cleaning, to remove pressing residue (mold release agent). There is a lot of info about LP’s and their care on the company’s website.
Last also makes a great LP preservative, which many record collectors have used since it’s introduction in the 1980’s. The only LP treatment I’ll use, it is not a lubricant, but rather a bonding agent that prevents the "fracturing" of the LP's PVC molecules from one another under pressure from the stylus. Great stuff, used by The Library Of Congress.
