I avoid using Astra, Feather and other blades with wax spots in TTO razors because of all the mess which is not easy to clean in a TTO and blade sticking to the doors as well. Nevertheless, I did want to try Astras in my new Krona. I carefully removed the spots (90% of them) with an old razor. It was fast and easy and it worked. The shave was very smooth, by the way. I like that long ATG strokes with pressure applied! That's why I like mild razors.
I use Feather blades and also notice the wax spots. It has never been a problem for any of my razors, including my Parker 99R. I normally remove the blade after the second shave and dispose of it. At that point, I clean my razor under the tap and leave it out to dry for the next day's shave.
I wipe the wax off my Feathers before I put them in my razor. I also clean my razor after each use, but that's just me.
+6 For no bother. I have started cleaning my razor after each use, just use a toothbrush with a little soap.
I don't exactly dislike them. If they are that big of an issue you can always lay the blade with the spots down so they do not stick to the doors.
