I've this blender from my mother's place, its about 2yrs or so. Anyways i use it everyday, and washed it straight away then i let it dry for the nexy time. BUT the problem is everytime before i use it, i have to rinse it with water to get this awful smell off before i can use it again. So i want to see if i can pull the blades off the jar so i can clean the in there but i've tried everything is won't come apart. Can someone help please?
