What liquid for ultrasonic bath

Hi to all...
On Ebay i've buyed a little ultrasonic bath.
I wont to say what liquid i need to use for wash the flux and clean PCBs...
In past i've used trelin with a paint-brush, but it's not the max with
plastic parts...
I've tried wth denaturated alcohol and water/ammonia, but nothing...

Thanks!!!!

 

We always used plain water (tap, distilled, whatever) with a bit of
non-sudsing detergent. What exactly are you cleaning?

Isopropyl alcohol works a lot better than denatured alcohol on rosin.
You can buy the 91% stuff in supermarkets if you look around, but the
70% often has glycerin and fragrances added; I'd stay away from that.

Acetone is also good for electronics (provided none of the components
are soluble in it!) but a major fire/fume hazard. Make sure you've got
good ventilation if you're going to mess with that.

 

Really thanks!!!

Enrico-

Take care that you don't damage circuit boards with your ultrasonic bath.
Such a bath works best on hard objects and may damage soft materials like
plastics or fiberglass circuit boards. It will create holes in aluminum
foil.

It would clean a watch band or eye glasses with glass lenses using soapy
water, but might damage plastic lenses.

For removing flux, I found a product called "water remover and fuel system
antifreeze" that contains almost pure Isopropyl Alcohol. Sometimes you
can find 98% Isopropyl Alcohol at a drug store. The 70% rubbing alcohol
doesn't work very well, since it contains a lot of water. I use an "acid
brush" to apply it to the circuit boards.

It might be a good idea to use hearing protection around the ultrasonic
bath. Even though you can't hear it, it has an effect on you.

Fluorolube?
