General Information:
The market for plastic microwave utensils is constantly changing. The best advice is to read the label.
Care:
Use only for microwaving unless label specifically says can be used for conventional or convection cooking. Read label and follow directions and cautions. All plastics do not have the same ability to stand high cooking temperatures; all microwave cooking tasks are not the same; some plastics cannot stand high temperatures reached in cooking high sugar or high fat foods.
Cleaning:
All microwave-safe cookware can be washed in the dishwasher, but follow manufacturer's label or guide instructions on where to place it--top rack only, or either rack. Or wash by hand in regular mild dishwashing liquid. Never use heavy duty mesh cleaners. If food remains after washing, use a plastic scrub pad. Never use scouring powders, scouring pads, or other abrasives.
If stains are left by berries or tomato products, put into utensil solution of 1 tablespoon chlorine bleach in 1 cup water (never any stronger!) and soak 1-2 minutes. Rinse thoroughly.
