No, you will not have an acidity problem with Vertrel^®.

The old chlorinated solvents (as well as the nPB solvent used today) can turn acid on a regular basis; sometimes they can get really nasty. The cause of this is the mixing of water with the solvent, say, after a plating operation. Chlorinated solvents require a "stabilizer" in the formulation to prevent the hydrolysizing of the water with the solvent. If there is too much water it will exhaust the stabilizer, which permits the solvent to become unstable and deteriorate into a chlorine-containing acid.

An acid degreaser is a mess -- the acid will actually eat away the internal surfaces of the machine. The acid will damage parts, create safety hazards, and even destroy the system if the situation is not remedied right away. Plus, the waste disposal costs are not cheap!

But that's not a problem with Vertrel^®. Since Vertrel^® contains no chlorine, it cannot turn acid. This means that Vertrel^® is much safer and easier to handle than the old chlorinated solvents.

Just a reminder: the brominated solvents will turn acid just like the old chlorinated solvents. Don't use them in applications where water is present. Ensure that there is a good stabilizer package mixed with the solvents. Or even better -- switch to Vertrel^® and leave these worries behind.
