## Questions & Answers

**Q: What are the ingredients?**
A: The can says naptha, hydrotreated light (64742-49-0), ethanol SDA 3C, isopropyl alcohol, n-propyl acetate, 1,1-difluoriethane.

The can doesn't tell you that it's malfunctioning spray nozzle will cover your hand in this stuff instead of your flux covered PCB.

**Q: Why does this product dispense solvent onto my hand instead of the pcb i'm trying to clean - this is unacceptable!**
A: My apologies but we need a bit more information in order to assist you. Have you used this product before? We sell thousands of cans of this solvent, via Amazon, per year and have not received a complaint such as this. It would have been better if you contacted us via the Amazon messaging system where we can carry on a lengthy conversation that offers the option of sending us pics.
