Question: Carbon stains have proven difficult to remove, and as a result of it much of the linens we process have been rejected. What is the cause of these stains, and how can they be removed?
- Rudi, Laundry Supervisor
Answer: I would not know the cause of the "carbon" stains, but if the stains are truly caused from carbon they will require a solvent to remove them. It will likely be required to spot treat these stains in order to get the highest percentage reclaimed. I would recommend a solvent-based emulsifier - wet the entire area of the stain. Allow the product to set for at least 2 hours, or if possible even over night, then wash as normal. If this results in less than 80-90% recovery, then apply as indicated, but wash in a stain formula bath to increase chemistry and mechanical action for better results.
Consider the source of stains. If they are gray or black they could be caused by the washers, from sources such as door gaskets or rubber in the machine (such as the drain hose), or even grease from bearings. The stains could also be metal stains or even ash stains from cigarettes.
