I have this actually on my list of things to do with this product in my Amazon cart.
Chemical Guys SPI_402_16, Heavy Metal Polish Restorer and Protectant, 16 Ounce https://www.amazon.com/dp/B00FALVXEQ/ref=cm_sw_r_apan_glt_i_PXST8G1BG7AKX1FXQEFQ?_encoding=UTF8&psc=1
That and apparently steel wool. I did a lot of research in this combo supposed to be the shit.
I think you can clean it with a degreaser and then polish it. I have polish only the exhaust and I could do it with a microfiber towel and Chemical Guys Metal Polish I Only used that one because of a sample. Im sure others will do a good job too.
You can use something like this: https://smile.amazon.com/Chemical-Guys-SPI_402_16-Restorer-Protectant/dp/B00FALVXEQ/ref=sr_1_7?crid=1TCVXTWFS2CKJ&keywords=steel%2Bpolish&qid=1653081913&sprefix=steel%2Bpolish%2Caps%2C151&sr=8-7&th=1 but only if you don't plan to actually use it for food/drink.
For the basket use Old English with a cotton ball and q-tip.
