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.
