    Once you put the lemon juice on where the battery has leaked, it will froth a little, neutralizing the acid.
    Used this on my 500's that had leaky batterys (500+ and a 4mb ram card with a battery)
    That's interesting, thanks.

    I might ask someone with access to IPC standards to see if this is covered, I wonder if someone has determined if it's necessary to neutralize before cleaning.

      That's exactly the stuff I used, Jif Lemon. It really brought up a shine on the corroded pins of the Amiga custom chips. The A3000 is still going strong, although I've not powered her up in a few weeks.

      As folks above have said, the reason for the lemon juice is to neutralise the battery acid. Mild damage can probably be cleared away with IPA, but in this A3000, the battery had sprayed goo everywhere. Lemon juice reacts with the battery acid and makes some water-soluble salts that are easily washed away.

      And yes, the term 'battery acid' is colloquial for the goo inside a battery. Even though most domestic batteries are alkaline ones, it's still often referred to as 'battery acid'

      • So doing some research it's lemon juice for alkaline batteries and baking soda for acid based batteries Found this page a good read https://nz.answers.yahoo.com/questio...1134030AA0jJ0m

          Would be the extra ram I think, 2mb was standard.

            I'd be surprised if it's just sheer quantity, the original 1+1 configuration shouldn't really be a slowdown unless you're trying to run lots of stuff. I guess it's possible though, who knows.
