Why has my Braun 5793 shaving performance dropped significantly?

If your Braun Electric Shaver's shaving performance has significantly decreased, it might be due to worn foil and cutter, so you should renew the Foil & Cutter cassette. Another possible reason is a clogged shaving system. To resolve this, soak the Foil & Cutter cassette in hot water with a drop of dish liquid, then rinse it thoroughly, tap it out, and apply a drop of light machine oil to the foil once it's dry.
