Clouded camera lens?

[Ether]

From wikipedia:

Acetone, which is commonly found in nail polish remover, is a widely available solvent capable of softening cured cyanoacrylate. Nitromethane is also an excellent solvent. Dimethyl sulfoxide can be used as solvent too. Methylene chloride is the most effective solvent, but is toxic. Gamma-butyrolactone is also effective at removing cured cyanoacrylate, and has low toxicity.

Methylene Chloride is found in many paint-stripping products. Read the label to find out.
