Hi, Tom -
There is a Naval Jelly made especially for aluminum. Phosphoric acid
solutions like Metal Prep can be used, but you have to make sure to rinse
them thoroughly. The exterior of the intake manifold should be painted the
Healey engine green color, so any discoloration shouldn't be a problem, if
it occurs.

Subject: Intake Manifold Cleaner
Can anyone recommend a safe solution for soaking the aluminum intake
manifold to remove rust and corrosion from the interior surfaces? I have
been using a phosphoric acid based solution for the ferrous metals but, am
not sure whether it is safe (discoloration, etc.) for aluminum.
Thanks,
Tom
