First, I wan to say my experience with wax is the opposite of yours.
To solve the issue you mention:
Someone here said he uses a pulley wheel fixed against something and runs the waxed chain on it. Sounds good to me.
IME large pieces of wax are caused by leaving the chain cooling for to long. I prefer to pull it out when hot. I know some say letting it cool down makes the wax last longer. That is not what I’ve experienced.
On another forum people shared their experience running the still warm chain throw a cloth and they liked the results.
I have to say silca is the best Ive experienced. Very little flaking.
