Machinery Talk

[MN cowgirl]

As my husband passed away last month, my children and I are faced with getting ready for a machinery auction.   The auctioneer said that there is a product by 3M that comes in a white bottle and costs about $40, that we could use to shine up the machinery....Does anyone know what this is called?   He coudln't remember.

also, any other tips would be helpful.  thank you.
