Uhm, I do not believe gold corrodes (ie, tarnish)
If you are seeing corrosion, it might not be gold. Maybe you are seeing gunk from soap (shower), skin oils, etc?

That was my thought as well. I’ve never seen 14 karat tarnish, much less 18k - but not big on jewelry.

Could it be 18k plated? If the 18k gold wears off, the base metal can sure tarnish/corrode.

Although gold doesn't tarnish, you may certainly have the byproducts from whatever else was up against it (or beneath it if plated).
Gold is fairly impervious. You can try soap and water, glass cleaner, vinegar, toothpaste, etc. I used to use simple green in my ultrasound.

This is going to sound crazy but my wife uses ketchup for cleaning tarnish off of jewelry (copper mainly is what I see here doing) - I think its basically the vinegar in it, and ketchup can be applied and will stay in place to do its work for minutes on end, whereas vinegar will just flow off and dissipate.

So how can you plate with 18K?

Me personally? I’ve never tried.
Here’s a link to some juice you can buy to do it in your basement laboratory.

I think it is usually done with electroplating.

First, I don't know what I'm talking about. From there, 18K gold is 75% Gold and 25% something else. Their comment about their solution being 99.7% pure doesn't sound true to me. More like advertising puffery. Had they said 75% pure, it might be believable.
