Chembyo Cleaner PP is a cleaning agent for developing processes. The concentration of Cleaner PP with water can range from 1:1 to 1:8, depending on the contamination level of the developing processor. In practice, it is usually diluted at a ratio of 1:4 to 1:5.
Use Chembyo Cleaner PP by diluting it with water in a ratio from 1:1 to 1:8. The mixing ratio with water depends on the contamination level of the developing processor. Drain the solutions you are using (developer) from the processor. Fill the processor with the Chembyo Cleaner PP mixture (the concentration depends on the contamination level of the processor) and leave it running for at least 40 minutes. Drain the Chembyo Cleaner PP mixture from the processor and rinse it several times with plain water. If using the undiluted concentrate, apply it to the cleaning surface with a brush, and after a few minutes, wipe it with a damp sponge.
