Care and Maintenance of SOSS® Invisible Hinges


SOSS® Invisible Hinges are shipped already lubricated and under normal conditions, require no additional care.

If needed, we recommend a spray lubricant, such as WD-40, which serves both as a lubricant and cleaner.  Apply gently, taking care not to overspray on the door or frame. Once applied, wipe with a soft cloth.

Do not use cleaning agents, solvents, or products like Brasso, because they can damage the finish and /or gum up the hinge links.

The following chemicals are not to be used on any SOSS hinge models with nylon links including, but not limited to the model #204, #208, #212, #216, #216FR, #218, #218FR, #220, #220FR:
