Over the years many of the rulers I use often have accumulated a bit gunk on them and some are now impossible to read along the length at points. I know I should have been more diligent and cleaned along the way, but I didn’t. So I’m posting this query now.
These are steel Starrett rulers. I’ve tried pretty much every solvent in my shop. Denatured alcohol. Rubbing alcohol. Acetone. Thinner. CMT orange tools 2050. Elbow grease and prayer. And largely all to no avail.
Any serious suggestions would be greatly appreciated. I feel like I’m missing something obvious.
Thanks in advance.
