It looks like WallyTools, which has no financial interest one way or another, is doing more controlled experiments with the product. Until it is completed, I think it would be best to stop using the suspect product.
I have not used gel cleaners myself. I do know of two instances where someone accidentally pulled the cantilever out of their cartridge using such cleaners. I suspect that they lifted the cartridge up too fast, and the force exceeded the limits of the design of the suspension (after all, the suspension is designed to resist forces from the stylus dropping onto a record, but not in the other direction). Both cartridges were quite delicate MC designs (one was an Allaerte, the other I cannot recall), so I don't know if this should be a concern for everyone, but, I do suggest a very slow and gentle lift from the gel using the cuing lever.
