I love this lamp BUT...
This is my first post, I tried to search for the answer on my own but had no luck.
I recently found an old lamp that I would like to use in my foyer with a black shade but it has some strange white stuff in between the lines of the lamp. I attached a pic. I'll try to add another.
Can anyone please tell me what this is and how should I clean it off?
Thank you all so much in advance for your advice.
