Fenton Hobnail Milk Glass Swung Ruffle Vase Crimped White Bouquet USA Vintage

Fenton Hobnail Milk Glass Swung Ruffle Vase Crimped White Bouquet USA Vintage. The piece is old and used, normal wear and tear as expected. There is some yellow crusty type substance on the inner sides. Probably could be soaked off. We attempted to used dawn dish soap and a bottle brush to take it off without luck. Goo gone or something may work better. Other than that the piece is in MINT condition. No chips, cracks or craising identified.
