Hi all,

Im working at place where we are working on scrap reduction right now. We got procedures in place to clean barrel (using aqua purge / dyna purge) but while using hot runner system a lot of carbon/colour contamination coming from manifolds and tool. We are doing plate pulls and de-tip cavities but sometimes that isn't enough. Is there any cleaning agent you could think of that I could run through tool that would help me out to clean it ? Our shop floor is running food related product so I would need something that wont stain tool and will be acceptable with our finished goods.

Thank you for any of your ideas.
