For All ARC 5 Shavers That Don't Use Cleaning CARTRIDGES
A good product and less expensive than what most other companies are selling it for. Be aware that similar and less expensive products may not include a lubricant which is important to help keep the foil cool and shaver blades sharp. Directions are in Japanese, but it's not rocket science. Empty the packet into the cleaned reservoir and fill to the line with water. Done!  Also, if you gently brush the whiskers from the foil and blades once a week (or more often if you wish) before cleaning, the detergent will last for two to three months.
