re: Front porch gas lantern question

yep, you can just open them up for cleaning...actually they need to be cool, so now is a good time, if they are already not lit.

I can't really see through the glass, but if those are the open-flame type, you can just light them with something like a barbecue grill lighter when done. If they are the kind that have the little cloth bag (mantle) that burns, then you will have to get more of those before lighting.
