<p>Before you wash anything read the data sheets. Not all parts can
tolerate water and/or ultrasonic cleaning.</p>

<div dir="ltr">Hi All,
<div>I have PCBs with SMD and TH parts, and also with plastic
connectors. SMD parts are machine soldered, TH components are
manually installed. Obviously some flux residue is visible
from manual soldering. </div>
<div>I have a 22L ultrasonic cleaner with a temperature
control. </div>
<div>The boards are quite large, like 100x250mm or so.</div>
<div>Wondering if you can share some experience using an
ultrasonic cleaner to avoid solvent based sprays and
mechanical cleaning.</div>
<div>There are some threads of using IPA inside small zip lock
bags to avoid evaporation, which seems to work well for small
boards and is relatively safe. However it's not my option due
to the board size. </div>
<div>I also see some "ultrasonic flux remover" detergents on
eBay, but for some reason they are all in the UK. </div>
<div>Also I found the specialized Flux Off by Chemtronics but
have never tried it. </div>
<div>Please, suggest.</div>
