I know sulphur based clays inhibit silicone from curing, but just how sensitive is it? I routinely used sulphur clays (I bought about 30 lbs years ago that I don't want to ditch) for sculpts, but now I have a bit of sulphur free I need to cast in silicone. Will the remnants of sulphur clay on all my tools be enough to cause problems? And if so, what would be best to clean them with before using to prevent cross- contamination?
