Royal Oak Trough Vase

Ok, so that name seems a bit grand for what I've got.....
I was at our local "dump shop" today, looking for some door knobs, and this poor thing was shoved on a shelf looking all dirty and discarded.  I mentioned to the serving man that it probably was "a thing" and maybe could be given a little more loving attention, so he whipped out his phone, google lensed, and told me it was a soap dish. I tried explaining that maybe it was a vase, but no, soap dish it was, did I want it for $2?
Yes, said I, and home it came.  My question is.....
How should I best clean it so as not to ruin the sticker, and should it be cream or white - like, how dirty is it?

thanks, Rosemary

Oh my heart ..... this was made by Crown Lynn and is Shape 21 made around 1950 and was decorated with paints by Royal Oak.

Just a wash in soapy water should help, but don't soak it as the paint may come off.

I have one, but not the wirework which was added by Royal Oak
