Gents,

Not gun talk but got a question about vintage kersone lanterns retrieved from my wifes grandmothers house. The last use was probably around WWII. The kersone in the resovoir was allowed to evaporate over time leaving an amber colored coating I'm unable to remove. The resovoirs are clear glass and the lamp might be known as a hurricane lamp to many of you. Any ideas as to what to use to remove the crud from the resovoir? I tried fresh lamp oil to no avail. I imagine gasolne might work but am reluctant to use it except as a last resort.
