Fascinating. I've been using a Panasonic Electric shaver for years. I clean it regularly, (but not like that) and replace the foil and cutters when I start noticing an increase in razor bumps (generally about 2-3 years lol).you guys should read this
The article makes sense, and here's a consideration for folks using disposable razors: if you don't have time to follow the procedure in the article, consider filling a glass with either distilled water or water from a Zerowater filter pitcher. After washing the razor, swish it in the glass of pure water before shaking off the excess water and leaving it to dry. No dissolved solids in the rinse water = no deposits left on the blades when drying.
You can test the theory yourself by letting tap water dry on a black piece of porcelain (coffee mug or plate etc.). Tap water will usually leave white calcium carbonate deposits when it evaporates. Distilled water and water from a Zerowater filter should leave no deposits.
