Most fiddling these days have to do with the printing surface being unclean. I also experienced issues with my X1C too.
But the most common problem is the surface is unclean(on both printers), and my soap to water formulation not being quite dialed in.
What printing surface are you using? I use a PEI sheet that I clean with straight isopropyl alcohol, and I almost never have issues.
PEI smooth and textured. Isopropyl alcohol works until it doesn't. That is why it is recommended that you use warm water with soap. I suspect the ratio of water to soap isn't dialed in quite right in my case, but I haven't bother to fix it just yet.
Either that, or don't touch the surface with your bare hands.
I can only speak anecdotally, but I've been using this sheet for ~4 years while only cleaning it with 90+% IPA, and I haven't seen any loss of adhesion. I expect to replace it due to scratches before I have any problems with the cleaning method.
I think the problems arise from using glue on it.
If I only print PLA without glue, one wipe with IPA and it's clean.
Glue on the other hand, it really sticks and you need water and soap.
I always use IPA to clean the bed too.
I have once used glue for a very thin print with lots of intricate holes in it.
