After having these type of shavers for many years I basically follow the provided instructions which are fine, but I've added a couple more stages to make it spotless (I only do this once a week so no hassle):
- Dust out and refit foil part
- Put liquid soap on outside of foil, drop some water on it while upside down and run in its sonic cleaning mode until it stops (20 seconds on mine)
- Take foil part off and rinse underneath of foil part for about 15 seconds and move the cutters by hand back and forth a bit to get any remaining soap/debris out. I then wrap the foil part in tissue and shake to get excess water off.
- Force some liquid soap into popup trimmer slider and run under water for a few seconds then close the pop-up trimmer (this is my addition to keep it clean as well)
- Use sonic mode whilst rinsing under top cutter blocks under water as per manual but I do this three times not once and from different angles/directions.
- I then dry the main shaver off a little with some tissue to speed drying.
- Leave apart to dry.
- Next time I use it I re-assemble add a couple of drops of the provided oil on the pop up trimmer and each foil and wipe off any excess after running it for a few seconds.
Sounds a lot but cleaning only takes a couple of minutes even with my extra stages and on the occasion I've bought one with a cleaner unit (as its the better deal sometimes) it sits in the drawer as its doesn't do as good a job and the unit needs cleaning/refilling itself. I also wonder how much extra wear the cleaner unit causes as it runs for a long time.
