Before I painted mine, I used this. It works well, especially for degreasing: https://amzn.to/2X83T80
I use Murphys Oil Soap.
Old fashioned sponge and soapy water is what I do!
I use lemon oil .
I've also always used Murphy's Oil Soap because it's designed to clean and lubricate wood. Wishing you the best.
Murphy’s oil soap
Murphy's soap or Old English furniture polish if they are not too badly built up with grime and dirt. Some rentals we had to use something stronger than these or even soap and water. Hope this helps Debbie
