How to Clean and Service Your Gobo Projector

Gobo projectors can last many years if properly cared for and maintained. Anyone with basic mechanical and technical
skills can remedy most projector problems through careful cleaning and inspection. To avoid causing damage, however,
it’s important to follow the recommended steps for your projector model. (Please note that GoboSource does not accept responsibility for unit failure or personal injury due to cleaning or repairs attempted incorrectly.)  

Below we share step-by-step instructions on how to clean gobo projectors, both interior and exterior models. For projectors that are exposed to a high amount of dust and dirt, such as a warehouse or exterior installation, the following steps should be performed every 1-3 months. In a low-dust environment, such as an office or retail space, cleaning is necessary only every 1-2 years.

We’ve also shared a gobo projector troubleshooting cheat sheet for common gobo projector problems below the full
cleaning instructions.

How to clean the ECO Spot Interior LED10, C-25, C40/40+, C60/60+, B90 and B150 GoboSource projectors:

1. Always unplug the ECO Spot Gobo Projector and let it cool down before cleaning or maintenance.
2. Unscrew 4-8 screws (depending on the model) on the outside perimeter of the backplate with a Phillips screwdriver.
3. Carefully take out your retaining ring for your gobo followed by your gobo. Clean the gobo with a fine micro cloth
4. After the backplate is unscrewed, carefully pull the projector straight back out of the aluminum projector housing.
   It should slide straight out along the side rails.
5. Clean the projector by blowing out the dust from the fans and heat sink with compressed air. Prevent the fan blades from spinning at high speed when using air, as this may damage the bearings. Gently blow dust
   from other parts.  
6. Clean inside and outside of aluminum housing with a damp rag or paper towel and wipe dry.
7. Visually inspect your projector for any signs of damage. Wire damage is most important to look for, as a bad wire
   can cause the projector to malfunction.
8. Now inspect the gobo and clean if necessary. The non-reflective side should only be wiped with a dry and clean microfiber cloth, while the reflective side can be cleaned with glass-safe solvent if needed.
9. The lens should also be cleaned. To remove the lens simply loosen the lock ring and turn the lens counterclockwise. Thoroughly clean it with a microfiber cloth, and re-screw the lens into the faceplate. It will need to be re-focused later.
10. When done, slide the projector back into the projector housing by lining up the two side slots on the front with the two slider rails. Slide straight forward until it’s all the way in place.
11. Carefully screw in the backplate screws, making sure not to strip them. Once the backplate is tight, the gobo projector is successfully reassembled.
