[volt-nuts] Best cleaning procedure for precision cirquits

[Andreas Jahn]

Hello all,

currently I am soldering my first LTZ1000A reference board.

Up to now I am cleaning my precision boards after soldering with
denatured alcohol in a pre-washing and a main washing procedure.

After this the last washing stage is with clean water to get rid of the
white haze from the denatured alcohol.

What is the best cleaning procedure? 
Is there one in a repair manual of any precision instrument?
Which of the near best procedure can be done at a home?
What are You doing to clean the boards?

best regards

Andreas
