I am a little confused what your problem with the ejector is. Do you mean the extractor?
The wood is very difficult in this instance, because any real cleaning is going to look, well, cleaned. My personal preference in this condition would be to make a tub of warm soapy water, with only a LITTLE mild detergent in it. Not sure how to quantify this.... if you take a soft bristle tooth brush and swish it around in the soapy water, it should not make many bubbles? Then take your soft bristle brush (old tooth brush is great) and gently GENTLY rub in a circular motion. As you brush, follow along with a old tshirt or lint free cloth and wipe up any excess water and dirt as you go. Do not allow water to soak into the stock. Do not allow water to sit on the stock. On the larger areas of the stock you can use just a damp wet lint free cloth (again an old tshirt works well) to wipe the stock clean.
I have read several different opinions from furniture restorers to NPS on products to use. Some recommend Murphys Oil Soap, some recommend Dawn, some recommend other products that are more specialized. I have had good results with whatever organic, natural, hippy soap my wife purchases. Since it is nearly useless on cleaning dishes, I figured it wouldn't harm a stock. After experimenting on a few spare stocks that were filthy, I worked out a decent process. Be advised, I have nowhere near the formal nor professional experience with wood working that I do with metal, so take that all with a large bucket of salt.
Once that is all done and you have given the stock ample time to DRY, now you need to engage in the argument of FINISH.
Regarding the metal work, it looks like you are happy with the results you are getting from the pads you bought. If you have any issues, or want a different way of doing things, let me know, I can still send you some notes. I personally do not use any metal (steel or copper) products when doing preservation/restoration work, but again, opinions abound.
