Cleaning cardboard?

[firstgenaddict]

IF you put install it and hold it EXACTLY correctly inside the car originally--
Does the overspray of spatter match the "correct" assembly line "masked" areas or do the spatter overspray patterns match a "slipped down" divider board?

I think it matches up with the "slipped down board masking"

As an aside to trans port the board around use piece of thin luan plywood -

WHEN YOU CLEAN IT... DO NOT ATTEMPT TO GO FOR 100% - especially given it's location-
Do all of this dry - and use a air blower to blow away after dislodging the contaminants.

1. take fairly stiff bristled brush and lightly use a circular pattern to begin to remove what ever you want to remove. - if that is not dislodging material - what is happening?
2 would a stiffer brush or more pressure or a more abrasive brush work better?

I'm not 100% sure what you're saying....did the factory have this divider in place when the original trunk spatter was applied? By "slipped down" do you mean the divider had been moved from original position when spatter was applied therefore probably done at some point by an prior owner?

Try eraser bags made for cleaning up pencil marks and dust on drafting drawings.
