Does not do the job
"Does not really clean without extensive rubbing. Even then does not completely remove the residue. Subsequently tried another glass cleaner that worked much better."

Rutland's Glass and Hearth cleaner is awesome and easy to use! It easily removes creosote, soot, and grime from fireplace doors and hearth. Just spray on and wipe off! This safe, non-acidic formula is thicker than other brands so it clings to surfaces without running, making clean up easy and mess free. 32 oz spray bottle.
Additional Information:

The thicker ultra cling formula sticks to the surface of the glass. So if you have a stubborn stain spray the surface, let it set five minutes, then wipe with a paper towel. It wipes right off, with no mess!
