hi speed airflow  from leaf blower could set static charge and    could

You really need a decision tree but there is my  process

1.  vacuum or blow out debris, outside.  I have used  a leaf blower before
for really nasty machines, or very delicate vacuuming,  all depends.  Goal -
remove all loose dust, particles, anything that  would gunk up a cleaning
process

2.   Soap and water,  inside and out.  There is nothing wrong with using
soap and water on a  computer board, hand dish soap.  Just dry well.  Use a
blow dryer  or fan, depends on how delicate

3.  Windex or glass cleaner for  glass surfaces only.

4.  Magic Eraser works great for plastic  covers after you've washed with
soap.  Or use that whitening compound  everyone uses for yellowed cases.
Forget the name.

5.  De-oxit  for connectors and pins and such

6.  Isopropyl alcohol for  finishing touches, with a q-tip cotton swab.

Use common sense.   Teletypes for example would not be the same cleaning
process as a surface  mount laptop  board.
