On Ground Glass
Published : 7th October 2003
I have a few ground glasses that have been pencilled by the previous owners.
I would like
to remove these markings and not destroy the factory marks.
Can I do this with a simple pencil eraser as someone told me?
Or is these another way?
A SAFE way...

To erase the pencil marks use Windex followed quickly by alcohol followed by BT67 and then Acetone. Or Windex followed by acetone. BT and acetone won't clean off pencil but they will clean off the Windex that will take off the pencil. Don't use an eraser.

I can't help Jeff with his question, but will soon like to pencil in 1:78 or 1:85 (Aaton LTR with 1:66/pumpkin combination). Any suggestions on this much appreciated (will speak to my tech as well, and look at Aaton’s XTR pdf Mitch wrote me some details- but I'm still thinking this through...
But are UK and European Dp’ s framing more for 1:78? It feels like it's throwing away precious negative area...

Using an eraser may remove the pencil marks with effort but may also alter the fine texture of the ground glass permanently - yikes. In the past I have successfully used a household cleaner called "Whistle" Spray into a small cup or its own lid if you want. Then dab a q-tip and apply gently. The marks should go away with no force.
Would recommend rinsing with water on following q-tips. This is a specialty hardware store item not at found just anywhere.
