ABSTRACT:
In a method for cleaning using terpene compositions, the generation of harmful precipitates is substantially eliminated or significantly reduced by adding a polar solvent, such as isopropyl alcohol, to the terpene composition. One to twenty percent of the cleaning composition should be alcohol, although it is preferred that it be in the five to fifteen percent range. The upper limit reflects primarily the desire to reduce the flammability of the solvent. Alternatively, the electronic devices can be rinsed with a terpene, alcohol mixture, but this alternative is much less preferred because of the flammability problem.
