Cleaning up Xtol

[Ed Richards]

I have a Delta plastic darkroom sink. I have Xtol dried all over it. It does not readily dissolve in water, and I do not want to scrub if I can avoid it. Anything not too toxic that dissolves Xtol?

I've had luck cleaning up developer stains in the past with a mild bleach solution. Fill up the sink as much as you can and let it sit for bit (overnight).
