Typical "rubbing alcohol" is 70% isopropanol and 30% water, you don't want to use that. You can buy a 90%/10% formulation in most of the same places, but I wouldn't use it in my system. Now, if you got 99%+ pure isopropanol, then I'd say yes. We use that here for cleaning small precision hydraulic components, and it works very well.
