Dutch gold is not a gold , it is a copper alloy and it will corrode and tarnish. You may need to cover it with a clear coat or to use a low karat real gold.
Good luck

Dutch Gold is a high Copper-content brass, beaten into a thin sheet. It is not surprising you are seeing corrosion in that atmosphere. Brass fittings need either constant polishing or a protective clear finish such as lacquer.

The best to avoid this expensive problem is not to use imitation
gold in this type of projects.
Imitation colour 2 1/2 is an alloy with 85 % copper and 15 % zinc. =
beaten bronze
If you heat this material with a lighter it will tarnish. This
material is sensitive to temperatures, UV light, humidity.
During the manufacturing beating process (heat), imitation gold
starts to oxidise and also if you protect with varnish after
finishing your gilding work you can't stop the slow and progressive
oxidation.
Humid surfaces, fresh varnish coats, and also working this material
without gloves will cause severe problems.
To avoid this problems the use of Genuine Gold Leaf with a
23 / 23,5 or 23,75 carats content will give you a perfect finish with
a very glossy or matt shine if you prefer.
How long genuine gold leaf can last ?
The oldest genuine gold leaf gilded surfaces known to me are at the
the Egyptian museum in Cairo and dates back 5.000 years.
