Hi I've only just started DE shaving at the ripe old age of 50 and bought the Mehule R89 instead of the EJ DE89 for the brass connection. However I saw a Geofatboy YouTube video where he suggests using a M5 nylon washer to help prevent the corrosion issue. I purchased some on fleabay as they cheap as chips but I'm using the razor before they have arrived. I just clean and dry the razor and blade in-between shaves.
Welcome to B&B, have some great shaves!
If you wait long enough the will be making a stainless steel variant sometime down the road no doubt. Nothing wrong with Zamak razors and I have a few myself and get awesome shaves and that is what counts.
Welcome to B&B Sam! My first razor was a EJ89 as well. It was a great starter razor. I’ve tried some vintage ones, modern SS etc…and one of my favorite ones is the R41 zamak head.
So, overthink it and have fun!
