The best way to clean a GEM

Good Evening all,

I have recently acquired an Edison Gem and have just managed to get 100 + years of crud from the motor after giving it a good soak in petrol and yards of kitchen roll.

Can I use petrol to clean the cast metal parts of the machine without damaging the finish and transfers ? or what would be an acceptable alternative solution.

Thank you in anticipation.

Metal parts that are plated or bare metal, yes. I in fact use lacquer thinner. But the painted metal case with gold details absolutely not. Any strong solvent will destroy the [paint and especially the decal filigree.

First just soap and mild dish detergent with a soft cloth. Then I use a product called New Life Furniture Masque. Go at it very sparingly or it too can ruin the gold filigree. Do not be in a hurry and do small areas at a time.

I finish up with OZ Crème Furniture polish which is a wonderful product that leaves a glossy shine.

You may but both products through Amazon.

Below are pictured results I had my a Columbia Q.
