True .... but it might be time to figure out a liquid combination that stains or is slightly corrosive. You don't need to melt things, just corrosive enough to etch, mar or deform glass or plastics of sensor lenses.

You clean everything up but realize that the liquid has permanently damaged an imaging lens cover, either with deep stains or corrosion.

Then you replace it but then it costs money and time.

And you do it over and over again
