I have a spray can of it. It's pretty nasty stuff. I didn't wear gloves and got a little spray on my arms, which stung.
I grabbed some paper soup bowls from the self serve line at Safeway on the way out the other day with some beer.
Sprayed the EO on the parts, it foams up. Left it on for about 1/2 hour and then went at it with a toothbrush.
Chrome either came off by itself or from brushing.
The yellow was in some locations, not others. Second app took care of that.
Then washed with soapy water.
