Manufacturers for different products use a similar system for maximizing their profits:
For example coloured printers that use expensive inks, which is more expensive than the most expensive champagnes to flush the ink tubes every time the printer is switched on.
I think that Braun has improved being able to remove the cap easily over the years, which is probably verified by the last date that somebody complained about removing the cap.
If still a problem than just widen the cap with fingers.
I think that Braun's definition of cleaning is keeping shavers hygienically cleaned, which is extremely important.
I think that the Braun Shaver Cleaner Aerosol Cleaner is an excellent and cheap method of cleaning, and oiling ANY shaver for any manufacturer, and it enables a better shave, when used just before shaving.
My latest shaver is the Series 7 790 cc, probably the first version (purchased years ago), which uses the expensive cartridge system to actually clean and lubricate automatically properly.
The aerosol last a long time probably a year, but definitely a long time despite being made of mostly alcohol, which should evaporate within seconds, probably at room temperature.
People who say it is a waste of money actually and literally don't know what they are talking about.
I shall try and tell you not only; how I use it, but why I use it based on objective facts (truth), and not subjective (misleading nonsense) facts:
1: NB! Keep spare; cartridges, and foil / cutters for when they have to be replaced.
2A: Clean the shaver: CAREFULLY use the brush to brush off any loose hair on the foil.
NB! If you; create an hole or damage the foil you should replace it immediately otherwise obviously you can scar your face.
2B: Remove the foil, and cutter and then carefully clean the foil and cutter inside and outside, whilst turning the foil to assist the loose hair to drop out.
2C: Brush loose hair from the rest of the shaver including the foil / cutter, and also the beard part etcetera.
2D: Oil all metal parts inside and outside whilst brushing out any loose hair.
2E: Place the cap securely back onto the aerosol.
2F: If the shaver doesn't say that it needs cleaning, then brush off the loose hair from the brush and store the shaver and the brush away.
3A: If the shaver states that it requires cleaning than after using the brush and aerosol to clean the shaver properly I would then use the expensive automatic cartridge cleaning system.
3B: Instead of storing the shaver and brush away I would switch on the cartridge, and if it is red, I would have to replace the cartridge with a new one:
3C: This is because either the alcohol has dropped down to a level that is too low (evaporated), and or the alcohol inside the cartridge has become too dirty.
3D: Carefully remove the old cartridge, and carefully open the new cartridge.
3E: Place the cover of the new cartridge onto the old cartridge (seal it), and then recycle it with normal Council's recycle box.
3F: Carefully, place the new cartridge into the cartridge system.
3G: The LED should change from red to green.
3H: Press the main start button.
3I: The cartridge system will automatically properly clean, and oil the shaver, and switch to stand-by mode when it has finished.
3J: When finished not only remove the shaver and store it, but unplug the mains lead from the cartridges.
4A: When using the shaver remove it from its case and spray some aerosol inside and outside of the; foil / cutter, because it creates a faster, cheaper, and a better shave, Try it!
5A: I would then wash, and dry my face.
5B: I should moisturize, but usually to lazy to do so.
6: I don't trust washing my shaver under the tap, despite Braun for years state that I should be able to - Don't trust the waterproofness of water being able to get into the wiring and rust possibly occurring.
I would after cleaning the shaver properly manually place the shaver into the cartridge to be automatically be cleaned and oil properly.
These notes should apply to any manufacturers' shavers and any metal thing used to shave with, because the main purpose is to make certain that the blades remain hygienic, and oil blades, shaves properly.
