3 Pack Essential Values of 30 ml Razor & Shaver Cleaning Fluid (Concentrate), 1 Bottle Makes 3 Refills / 474 ml of Refillable Shaver Cleaner Fluid Solution | Replacement for Cartridge Refills

Verty pleased with item

I use these concentrates in my Braun Clean & Renew shaver cleaner.I use 99.9% isopropyl alcohol to which I add 10% water. To 480ml of this mix I add 1 bottle (30ml) of this concentrate. This is then sufficient for 3 refills of the cartridge (170ml) in the Braun cleaner.I find the shaver is cleaned just as well as using the expensive Braun original cartridges - and there is a pleasant lemon smell.It is important to thoroughly clean the cartridge between each refill. Other than that, this is a quick, simple and effective process.The 3 bottles in this order will last me well over a year. I am rather chuffed.NOTE, the seller recommends using isopropyl alcohol that is at least 70%. I find 90% to be the most effective but the evaporation rate is higher. It's a trade off.
