Primarily Petroliana Shop Talk Forums Shop Talk Petroliana Forums General Petroliana Discussion oil bottle spout & rack cleaning

This weekend in bought a set of 8 oil bottles and a rack for them. They are mobile spouts and the rack is a Jay Rhodes Co. Rack. My question is how do you guys clean you oil spouts and racks? Do you just soap and water or do you dare try to buff on them at all. Do you like to keep the patina on them? I don't want to hurt the value of them down the line.
Also, what do the letters on the oil spouts mean? They have A,E,AF,BB,Artic embossed on them. Is that just the grade of oil for that jar? Thanks for any information. If you need pictures posted let me know.

The letters are the grade.

Here is a couple of pictures of the rack and bottles if it helps.

They look nice. I would just use soap and water on them.

They look fine to me,just the way they are.
I wouldn't polish them are clean the glass @ all.
