AppleDesign powered speakers grille removal.

[Burgertrench]

Does anyone know how to remove the metal grilles from the original AppleDesign powered speakers? I'm preparing a set to retrobrite and don't want to risk causing corrosion on the grilles, but cannot work out how to remove them. I've tried a heat gun and some force from inside but they won't budge.

I never had any rust or other activity on metal.
I think i would simply risk it, they are probably glued in.

When I've retrobrited cases, I only remove metal where its easily practical or I can re-attach it using the original method (I really am not a fan of even internal modifications and only recently did a IIvx -> Q650 upgrade and it took me years to work up to that).
Sorry, long way around - I generally leave in metal shielding and the like when retrobriting and in my experience, using the original solution, the metal does not rust while it is in the solution, but will start to do so IMMEDIATELY after it is removed and rinsed off with water.

I generally keep spare towels, paper towels and a hair dryer nearby when finishing up some of the more important projects (like when I did my Q700 this summer) to make sure that after I thoroughly rinsed the parts, the metal pieces that could not be removed were dry and did not corrode.

I don't have direct experience with the speakers, but my experience with the other pieces would lead me to trust tecneeq's advice, while making sure that they were well rinsed and dried afterward.

Thanks for the advice, I've had it in the solution for a fair few hours and the metal is fine. I've had shielding in the solution but was hesitant to put a visible part in case it affected the appearance.

Good tip on the rinsing, I'll follow this for sure. Next is to figure out what to do about the drivers which have foam rot.
