This depends on the type and model of citrus juicer you choose. A basic manual citrus press or reamer may be completely dishwasher safe, so you can throw the whole thing in and have it clean in no time. Of course, you couldn't put your whole electric model in the dishwasher, but some or all of its removable parts may be dishwasher safe.Always check the manual before you put any of your juicer's parts in the dishwasher, as they may get damaged if they're not dishwasher safe.
