I just purchased the Vitamix 7500 about two wks ago (tomorrow, 11/25, will be 2 wks) and there all small diagonal scratches as well as a bunch of tiny scratches inside my container (from the middle to the bottom and corners). I was the container per the Vitamix instructions (fill it half way or less with warm water, 1-2 drops of dish soap and run for 30-60 secs), dry it with a super soft microfiber towel and only use a rubber spatula. I usually make frappuccinos, ice cream, sorbets and smoothies (made soup once). At first I thought the scratches were minimal, but I looked at it closely in the light and it has tons of little scratches/marring. I'm guessing it's from the tamper. I asked another Vitamix demonstrator and their container is not scratched and I viewed another demonstrator on Youtube and their container looks new after a year's use. I'm also seeing little slight bubble discolorations on the container. It looks like it has dirty spots, but when you wipe it, it's just the plastic. I don't have a dishwasher and I haven't used any harsh or anything other than 1-2 drops of dishsoap. I'm calling Vitamix tomorrow, but has anyone experienced scratches/marring in such a short time? I still love my machine!
Thanks!
