Hello everyone! This is my first post here and it's going to be a little bit of a rant but I also would like some guidance. 

  
I've been into the vintage computing hobby for around 3 or 4 years now and the Commodore Pet was one of the very first things that caught my eye. I have some of the bread bins but something about the terminal look and the monochrome green text always spoke out to me and I've never stopped wanting it. Thankfully this popped up on Ebay for a not too insane price! Now the work begins and for that I seek guidance.

How in the world do I clean this thing? I suspect like many of these machines this was in a school environment. There is grime, marks, and even old tape on the back. I would like to clean it as much as possible.

  
How should I go about cleaning the motherboard? I know isopropyl alcohol is a common solution but PCBs from this era are visually different and I know much of the solder may have lead considering the era. Not sure of any of those factors would effect that so I figured I'd ask. Most of it is just caked on dust. 

How should I go about storage? I've seen the SD2PET but I haven't seen any alternatives. If there are any quirks with that solution or alternatives worth knowing that would be cool.

Finally, what precautions should I take regarding the microwave transformer type of power supply? I'm considering replacing the power supply like this user did here down the line: [https://forum.vcfed.org/index.php?threads/replacing-the-power-supply-in-a-commodore-pet-8032.1070496/](https://forum.vcfed.org/index.php?threads/replacing-the-power-supply-in-a-commodore-pet-8032.1070496/)

I'm aware these things can put out crazy voltage and take lives which is part of why I want it gone. I also just want a new power supply in it so it's less likely to fail and destroy it.

  
Thank you to all who read and reply! I'm very happy and excited to get this thing clean :)
