VoXiE,

Was this a New puchase or a Dell Outlet Used/Refurbished purchase?

Auto parts stores have good products to clean plastics.

Brand new.  Received at the end of January.

My aurora had residue and greasey finger prints on it to . From some research I found out it was dirt. and most likley the mexican fella ate a toco before assembling it.. They don't have air conditioning in those plants just fans that blow dust around. I spent a couple of hours cleaning up my PC after recieving it.

What worked best to clean up the mess?

Go to Auto Zone / Checkers ect , they have products that clean and polish plastic. I bought a bottle of one to clean and restore my headlight lenses, look new now. I forget the name but it takes scratches and scuffs out,  Now I have never tried it on black textured plastic, but I think they have something - auto restorers/ detailers use it

Thanks for the advice flotown...I'll give it a try.  Would a product like this http://www.amazon.com/Plexus-Plastic-Cleaner-Protectant-Polsih/dp/B000HG8ZJ0/ref=pd_sxp_f_pt also do the trick?  Also, do I risk voiding my warranty if this fix does more harm than good?

The old Logitech 200 my kids used is hammered with soda, ect. I tried the olive oil and it cleaned off all of the gunk and left it shiny but not oily. The are still scratches of course but it looks new on the part I cleaned with olive oil. I used windex on the bottom and it's clean but no shine. I used a paper cloth, so it will work if there are no scratches.

As crazy as it sound some auto restoration sites say to use peanut or olive oil to clean and polish black plastic,. I got an old black keyboard, I'll try some olive oil on the plastic.
