# Can I wash my PCBs denatured alcohol

I have denatured alcohol which, according to wikipedia, is composed of roughly:

• 85% ethanol
• 10% water
• 3% methanol
• 1% aceton
• 1% pyridine

My solution has a blue color. Can I use this as a replacement for isoprop. or pure ethanol to clean my PCBs?

• It depends on if the residue that is left will affect your PCBs operation. – PlasmaHH Feb 18 '16 at 11:39
• IPA should be obtainable (for private citizens) at or below $5 per liter at larger quantities, absolutely no more than$8 per liter bought per liter, or \$10 ~ 15 per liter at sub-liter quantities. With 1 liter you should be able to clean dozens if not hundreds of square meters of PCB when used in the correct sparing manner. I think buying a small bottle of IPA isn't going to be the major cost of your hobby. – Asmyldof Feb 18 '16 at 12:42
