Chemical reaction! Could be, like putting
silverware next to stainless steel cutlery in the dishwasher...exacto blade
(stainless), VDB (silverware)...ROTFL I'll let you know. Thanks

Clearing?
If there's anything that would be the chemical reaction between
the
blade and sensitizer, or multiple light scattering under the
blade.
If you do "sham exposure" that is to place the blade on
sensitized paper
for 8 minutes WITHOUT any exposure and then process,
you'll know.
