The recommended dishwasher setting for Pyrex is to wash it in a regular 1-hour setting or in the Eco setting. It's possible to get good results in both of the options. If there are a lot of other dishes in your dishwasher, go for the long wash cycle option to get the best opportunity to remove the foods. But please make sure to have ample space around the dish so the water can be sprayed uniformly on the dishes.
