As a fan of cleaning old electronics I would make a few comments:
Look at a number of past threads on cleaning,
Not everything really needs total cleaning, some things should not be
"cleaned" and some labels can be removed with water. Other things need to be
cleaned but can't be cleaned with water/soap (such as HP clear vinyl tubing
in power supplies)
Start off with some things that are worth less.
To really get stuff off, you will need a surfactant but surfactants can
remove labels and other marks so you have to be careful what and where.
I would not soak pcbs, that can get a lot of water into stuff like pots, and
transformers, carefully brush and hose off with water. Avoiding
spraying/soaking into stuff like pots and transformers.
I would not "dry" with a hairdryer too hot too quick, blow off as much water
(taking as much dissolved salts) as you can with lots of cold air, I use a
clean leaf blower on at night when there is lots of water in the air(no
static).
Then possibly rewash, reblow, rewash and reblow (triple rinse)
Then dry in a 120F ish temp with some air movement for 24 or more hours.
I have used an old fruit dehydrator, worked great, that died from too much
use, Now I have been using an oven with a 50W bulb and small crack in door
where cord goes in (gets just to 115F)
Take lots of pictures before things are taken apart, saved me many a time

Just some thoughts
