Yinke Reuse Cleaning Cartridge with 6 Cleaner Concentrate Fluid Refills for Braun Clean and Renew Refill Cartridges CCR, Replacement Shaver Cleaning Fluid for Clean&Charge Cleaning Station (6+1 Pack)

I am assuming it sterilises razor head, which is what is for. Tray fitted Braun series 9 razor and sterilising solution in convenient packs to which you add water

I like the refillable cartridge idea, but the cleaning fluid doesn't work and it's leaving my shaver covered in grey sludge

It cleans the razor well though it takes longer to dry as it is water based. When refilling the maximum line is difficult to see a darker more bold line would help.

Good value for money It could do with a stronger citrus smell. I will be buying them again great quality product

Container great, however cleaning fluid is bad. It stinks when you are shaving and produces white scum on razor body. It does not dry properly. Do yourself a favour and fill the container with ROZAR liquid, you will thank me!

Very good saving on original Braun unit. Easy to use can’t see any difference in quality from Brauns Cartridge, Shaver was cleaned well couldn’t wish for anymore will buy again.

Superb value for money

This stuff is not worth it the money. It does not clean my shaver very well leaving hairs on the outside, it smells strange. It’s difficult to fill the Carthage and there is no fill line that I can see. It just doesn’t work very well, takes a long time to dry and is poor quality not easy to use. The only thing that I can say positive about it is that it was cheap
