All three of these products work like a champ !! To me my gm is reserved for filthy jobs so its (gold) in my opinion,,,, I use it when I need to use it.. RSF is strong enough to do the job on its own...RSF has the most poly cleaner in it lb for lb. it just seems many want a boosted version. Me, I’d use the RSF Free and Clear and add a lil citrus solve when needed.
