I had one of these for a few months now and it is very powerful but the container/carafe seems flimsy compared to the poly-carbonate one on my Kitchen Aid. I've always cleaned that in the bottom rack of the dishwasher and I use the added heat setting. No problems. Is the Blendtec carafe dishwasher safe? Will there be any warranty issues if one fails after dishwasher cleaning? Up until now I've been using the recommended cleaning method, dish soap and hot water blended for a few seconds. Today I made a Middle Eastern marinade and it didn't clean it sufficiently. I had to rinse it in the sink and towel dry afterwards. It still had a faint odor of curry paste.
