Cleaning Vehicle plates

I now own a 1953 Willys Jeep MD 40675; appears I have most plates belonging to her though illegible. Hoping someone can tell me the best method to use for cleaning them. I would rather have her original plates so do not wish to order duplicates. Willing to begin restoration with this cleaning task. Tx for any help with this.

I use paint thinner and a razor blade at a flat angle to remove paint off of the data plates. I have seen guys use oven cleaner and brake fluid to loosen the paint for removal.

Okay tx so much. I’ll attempt and send pics.

From an oven cleaner guy, just known the thing about oven cleaner - it works and no going back.
