PROCEDURE FOR BATH OPERATIONS

1. Loading and Soaking: Place items into the tank and wait for signs of paint softening (20-60 minutes). This may vary based on the type, age, and number of paint layers.
2. Removing and Drying: Take out items, briefly dry them, and prevent paint from hardening. Note: Ensure softened paint does not start to harden.
3. Paint Removal: Scrape off softened paint or use high-pressure water. Repeat if needed. Note: If paint persists, repeat dipping process.
4. Surface Finishing: Rub timber with dry steel wool, metal with steel wool or scouring pads. Note: Wear gloves.
5. Cleaning: Wash the surface with Methylated Spirits and a scouring pad or steel wool.
6. Maintenance: Replenish product, drain sludge and clean the tank regularly. Note: Regular tank cleaning ensures optimal performance.
