Here’s your quick guide to buying the accessories and parts for your Braun Series 7 790cc Pulsonic Shaver.
First and foremost, when you purchased your shaver, you would have noticed that you had to insert a clean & renew cartridge into the shaver’s clean and renew unit. The unit and fluid are a fantastic facility for keeping your shaver clean and hygienic after every use. You simply insert your shaver head into the unit and your shaver will be cleaned and recharged without you needing to lift a finger. That said, I would recommend to keep your fluid lasting longer, that you use the cleaning brush that comes with your shaver to first manually remove hair and debris from your shaver’s foil and cutter block after each shave. But that’s up to you whether to do that or not. I prefer to do so personally. The Clean and Renew system was and still is a revolutionary and fantastic development in shaver technology. Using hygienic cleaning fluid with a lemon-like fresh scent to ensure your shaver performs like new after each use and clean. But, each cartridge will only last around 2 months and the last thing you want is for it to run out without you having any refills about – one gets used to the hygienic clean, feel, and fresh smell! So the first thing that you need to buy for your Braun 790cc is a pack of clean & renew cartridges. You can usually buy these in 3 or 2 pack forms. Most places tend to sell either the 2 pack or 3 pack version rather than both.

Braun recommend that you replace your cutter and shaving block every 18 months. As of course, after repeated use, the precision and effectiveness of these shaver parts will decline. Worse still, the shaver foil may eventually break, forming sharp edges that may cut your skin. So you will definitely want to make sure that you replace these parts at the recommended intervals to maintain top performance.

Other than the above, you might like to carry a spare charger cord with you. This is useful if you frequently go travelling and don’t want the hassle of disconnecting your charger cord from your clean and renew unit or having to pack it each time.
