How can I tell when I need to replace the detergent in my wash unit?

The effectiveness of iQprint® Wash will decrease over time as it becomes diluted with residual resin, however, it is possible to extend its life by passing it through a filter to remove any resin suspended in the wash material. You will need to replace the solution when you notice it becoming less effective at removing resin from your printed models. You can normally tell when the solution needs to be replaced when it becomes discoloured or cloudy.
