The following procedure is recommended before every scan:
1) Thoroughly wash the glass scanning surface with ultrapure water
and wipe with a lint-free tissue.
2) Repeat the wash with isopropanol to remove any visible smears.
Use ethanol to remove any remaining residues. If dye contami-
nation continues to be a problem, slightly wet a cloth with
acetone and wipe the glass.
Important:
the acetone must not
contact anything other than the glass. The paint can be damaged
by acetone.
3) If the silicone mat is being used, rinse it under warm water.
Gentle lab soap may be used, but the soap must be completely
rinsed away before use. The silicone mat may also be rinsed with
isopropanol if needed. Dry the silicone mat with a lint-free tissue.
The scanning surface is plate glass, which can be cleaned with any
non-abrasive glass cleaner. Warm, soapy, distilled water or isopro-
panol can also be used. Do not use scouring compounds or abrasive
scouring pads; the glass can scratch, which can affect the scanned
image.
