After each use, scoop or swirl the grounds into the trash or compost (not the drain, where they clog it), then unscrew the plunger's filter discs and wash every part with warm soapy water. Every week or two, soak the metal filter and beaker in a mix of baking soda or diluted vinegar to cut the coffee oils that turn a press bitter and rancid.
Recommended Bin the grounds, disassemble the plunger, wash with soap — deep-clean the filter monthly for oils — A French press tastes muddy and bitter when old coffee oils build up in the mesh, so the two jobs are removing grounds after every brew and dissolving oils regularly. First get rid of the grounds without sending them down the sink: tip most into the trash or compost, then swirl a little water and pour that off too, or scoop with a spatula — grounds swell and block drains. The filter is the part that actually gets dirty: unscrew the plunger into its stack of discs (a cross plate, the mesh, and a spacer), and wash each piece plus the beaker with warm water and dish soap, using a soft brush on the mesh. For the oily film soap leaves behind, once a week or two soak the metal parts in warm water with a spoon of baking soda, or a 1:3 white vinegar and water mix, then rinse well. Most glass beakers and filters are dishwasher-safe; dry everything and leave the press open so it doesn't hold a stale smell. Never use steel wool, which scratches the mesh and glass.
