The IPA-Based Flux Remover - IsoClean™ is a mild, non-corrosive, ESD-safe circuit cleaner that quickly and easily removes fluxes, pastes, light oils and grease, as well as organic residues. It is effectively used as a circuit cleaner and stencil cleaner.
IsoClean is the strongest IPA-based cleaner on the market. While most IPA-based cleaners contain up to 30% water, this cleaner contains virtually no water and is undiluated by airborne humidity. 100% volatile, it evaporates cleanly with no rinsing required. Safe on all materials including components, connectors, cables and elasto-mer.

Q - What is "flash point" and why is it important?
A - A “flashpoint” is a temperature at which a liquid will burn and keep burning. Flash point assumes these is a spark or some other source of ignition which contains enough heat to warm the liquid to start the fire. A hot soldering iron or the heating elements in a hot air gun both are good sources of ignition, as is any arcing electrical motor or relay.
Given enough heat, almost every liquid has a flash point. However, it is a customary practice in the industry that any chemical with a flash point above 100° C (212° F) is considered nonflammable. For example, the Heavy Duty Flux Remover – SuprClean™ is considered nonflammable. This makes the factory a safer place to work.
Here’s another important thought: it’s not just the solvent you select that determines worker safety, it’s also how you use that solvent. The MicroCare TriggerGrip™ cleaning system was specifically designed to improve worker safety, even with flammable solvents. We strongly recommend the use of both of these products in any applicable benchtop cleaning environment.
Higher Solvent Flashpoints Make Safer Products
Obj--Flame-test.300x300.RGB.72dpi.2Look at the current MicroCare product line: the General Purpose Flux Remover – Flux Remover C will not burn. In the test photo, below, a sample of the product simply will not burn, even when a match is applied to the vapors. This indicates an extremely high flashpoint and a very safe product. Interestingly, the General Purpose Flux Remover is nonflammable even though it has flammable ingredients because the mixture is an azeotrope. (The flammable ingredients include a bit of alcohol, another ingredient called “trans” and more.) The General Purpose Flux Remover cannot be made to burn below 200 degrees. That’s one reason why so many people select General Purpose Flux Remover for their benchtop cleaning.
Now let’s move down the flash point scale. Alcohol solvents, in the form of our Alcohol-Enhanced Flux Remover – ProClean™, the MultiTask Surface Cleaner – MultiClean™ and the Alcohol-Based Flux Remover – IsoClean™ products, have a flashpoint of about 15° C — practically room temperature. Similarly, the No-Clean Flux Remover – VeriClean™ and the VOC-Free Flux Remover – UltraClean™ has a flashpoint of -2° C. These solvents are great cleaners but flammable. That’s why we sell so many TriggerGrip tools.
In the U.S., anything with a flashpoint below 55° F / 15° C is considered “extremely flammable” and may become, if mis-used, a significant safety hazard. Some Chemtronics products, for example, use isohexane. Isohexane has a flashpoint of – 65°C. While many of the “extremely flammable” solvents are good cleaners and dry quickly, at MicroCare we have made the safety decision that we will not package anything that is as flammable as isohexane.
So, in summary, a low flash point means the solvent is more risky or dangerous than a high flashpoint. High is good; the higher the better, until you get all the way to the highly desirable “nonflammable” rating.
Q - My technicians are complaining about solvent fumes, what can l do?
A - Let’s assume your situation is in a factory or workshop environment, where people are cleaning PCBs or stencils by hand. There are several things you can do, but try this three-step process first.
1. Check the Ventilation
First and foremost, you must make sure your work areas are properly ventilated. How do we define “properly ventilated”? Try this simple test. If you lit a smoke stick in the work area, would the smoke from your cigarette rise straight to the ceiling, or would it move off to one side fairly quickly and be dissipated through the room? If it rises straight to the ceiling, your ventilation would be considered poor. Good ventilation is essential in a modern factory. It improves worker health, reduces absenteeism, and boosts productivity. You need to install fans in the area, open windows, install dedicated fume extraction equipment, and/or get your facility manger to turn up the A/C quite a bit.
2. Switch to the TriggerGrip Dispensing System and Improve Your Chemical Handling Processes
The TriggerGrip™ system from MicroCare dramatically cuts solvent consumption and thereby also cuts solvent fumes. Proper chemical housekeeping can go a long way to reducing fumes. Open trays of solvent are obviously a bad idea. Improper use of cleaning machines can create clouds of fumes that could choke a horse. And, on the benchtop, make sure everybody is using their TriggerGrip™ dispenser. (And using it properly, we might add — you wouldn’t believe some of the things we’ve seen!) If in doubt, call your sales rep for refresher training for your people, or get a copy of the MicroCare instructional video. Available on either video tape or compact disc, it’s only eight minutes long, but can make your life much, much simpler.
3. Change Your Solvent
You might want to consider changing your solvent. Ten or twenty years ago, the only ozone-safe solvents we had were smelly, slow-drying and hard to use. Technology has made a lot of progress in just a few years, and today’s solvents tend to be fast-drying, nonflammable, much more powerful and easy to use. So switching to a low-aroma solvent such as the Lead-Free Flux Remover – PowerClean™ (#MCC-PW2) the No-Clean Flux Remover – VeriClean™ (#MCC-DC1) might make a big difference in your work area.
If people are still complaining, try using the slow-flo brushes on their TriggerGrips and/or the Lint-Free Solvent Wipes. Both of these products cut solvent consumption, make the cans last longer and reduce chemical fumes.
