Lesson 2.6 Flashcards
General Cleaning Procedure
Step 1
Rinse the tank with water multiple times to remove residual chemicals.
Step 2
Wipe all surfaces with a clean, lint-free cloth to prevent contamination.
Step 3
When water alone is insufficient, use a strong oxidizing solution to remove stubborn stains and residue.
Different parts of the processing tank require specific cleaning methods to address various types of stains and residues.
Specific Cleaning Methods
CAUSE
Oxidized developer solution leaves brown or yellowbrown stains
Cleaning Developer Stains
Cleaning Developer Stains
Cleaning Method
Use soap and water for mild stains.
For stubborn stains, apply a strong oxidizing solution (e.g., potassium permanganate or a commercial developer cleaner).
Rinse thoroughly to avoid contamination.
Stop bath solution can be used for effective cleaning.
Cleaning the Developing Tank
The acidic nature of the stop bath
neutralizes alkaline developer residues,
preventing contamination.
Cleaning the Developing Tank
After using a stop bath, rinse the tank
thoroughly with clean water

Cleaning the Wash Tank (Algae
Removal)
Cleaning Method:
Use a commercial bleach solution to kill and remove algae buildup.
Rinse thoroughly with clean water to prevent chemical contamination.
Clean the processing tank daily to prevent chemical buildup
Daily Cleaning
Inspect for leaks or cracks that may cause contamination or loss of solution.
Inspection
Use separate cleaning tools for each tank to prevent crosscontamination
between developer, fixer, and wash tanks.
Separate Tools
Drain and refill solutions regularly to
maintain optimal chemical activity
