Fix stain on JBL L36

[Patm300e]

I just acquired a pair of JBL L36 Decades. Both speakers sound great even though the woofers are not original. The cabinets need some work. One has a large stain on the side:
What is the best way to remove this? I haven’t tried anything yet, just looking for suggestions.

Thanks, Pat

Steel wool (0000) and lemon oil lightly rubbing following the grain maybe?

I'd try Barkeep's Friend. Had a stain like that on an oak table I scored at a yard sale, and it was far, far worse. Damp rag, sprinkle on rag, scrub, wipe with another wet rag. Works easy-peasy.

Oxalic acid is the main culprit in barkeep's friend. Nice score, btw.

If you've not tried anything yet, just start with a damp cloth and see what happens. Could just as easily be soda or coffee. Don't go abrasive.

I will try damp cloth first and let everyone know the results.

I have tried wood bleach with great success. A recent pair of speakers( JBL L26s same cabs as yours) I picked up had bad black water stains on the tops where the previous owner must have had plants.
At first I was skeptical that the wood bleach would work without cooking the wood and making it blotchy. It didn’t and the black just disappeared.
I prepped the speakers by sanding off the old finish first then followed the directions for the wood bleach powder mixing with water and applied.
I had to apply it several times but, it really works.
You can get it at any hardware store in the paint section or can order on line from Amazon.

Note: The wood vaneer on JBL speakers is really really thin. Be super careful sanding them. Personally, I wouldn’t use anything lower than 120 grit and would hand sand vs, using a power sander. I finished with several coats of natural tint Watco Danish Oil. The results were spectacular.

Ok, used damp towel and some elbow grease. The towel shows something coming off , but the stain is still there. Little lighter though.

Try lemon oil and rag maybe?

Update: I did the 0000 steel wool and that lightened it to the point that it is barely visible. Then I used tung oil to refinish.
