I have been used isopropyl alcohol for cleaning my Newton MPU 2000 regularly basis,
and no problem at all at least for me. I clened with "Kodak Lens Cleaner Paper". Usually 2 or 3
drop of IPA on Newton or drop it on cleaning paper then should be cleaned. This means to avoid
IPA permeated to newton inside. How much amount of isopropyl alcohol did you put to newton?
Does the isopropyl alcohol permeated into newton?
