Cleaning of un-cured surface mount adhesive should not involve the use of alcohol's, as many of the epoxy chemistries will actually react or cure prematurely in the presence of IPA, especially in small stencils apertures. Loctite has a product known as 7360 Surface Mount Adhesive Solvent (Item # 25658), which is an aliphatic ester blend. The "flash off" or evaporation times are slightly longer and it may require a "dry wipe" prior to the application of new adhesive. Once the old un-cured adhesive has been removed, a wipe with IPA will speed up the flash off time of the 7360 as well. Hope that helps you out.
