Where great old Macs live again!

Introduction
I have been asked to blog about my cleaning and restoration work few times. So this is my attempt to explain the
processes that I go through. I should start by saying that I have no professional training in electronics or working
inside Macintosh computers. Everything I have learnt is from reading books and articles online. Therefore I can not
take any responsibly if you damage your machine or yourself.

Tools and Aids
I will start with my work area, I have mine set up in my loft so it's doesn't matter if I make a mess. I have a G4 set
up to view Apple service manuals, which are PDF files that cover specifications, troubleshooting, and take apart
procedures. These manuals are not available to the general public, but if you do a bit of searching on Google you
can find them. Half of the work area is covered with a grounded anti static mat. When working with boards that
are sensitive to static, it is important to use one. I won't go into ESD damage prevention, as there are plenty of
other places to read about it.

Most of my tools are made by Wiha (www.wiha.com). They are good quality tools and they have nearly everything
in their range that you would need to service Macintosh computers, including the long Torx T15 screwdriver for
opening compact Macintosh. I have a set of precision screwdrivers and some that have long shafts for hard to
reach places. I have a set of tweezers that are very useful for removing dirt, fluff and retrieving dropped screws.
Another useful tool is the famous black stick, used for prying things open and routing cables. This is probably the
tool I use most after a number 2 crosshead.

For cleaning most parts I use a multi purpose house hold cleaner diluted with water. I have it stored in a plastic
bottle that has a pump spay, that makes it easier to apply. I use toothbrushes, lint free cloths and sometimes a
non scratch scourer, on the cases if they are very dirty. I also find a small paintbrush useful for dusting in hard to
reach places. For cleaning and dusting circuit boards, I use a ESD brush and swabs soaked with Isopropyl
alcohol. If the board is very dirty, I may try washing the the board which I will go through another time.

Next time, I will open up a Macintosh and run though the process in detail. Let me know if you have any questions
or comments.
