Removing and cleaning the front panel of a 42S

[mfleming]

Hi Tony,

If by "removing the front panel" you mean separating the case halves, I don't think that would be of any help. It is possible to remove the faceplate by using the heat from a hairdryer to soften the glue beneath, then lift the faceplate from the front of the calculator. Not recommended though since any bend you might make in the metal faceplate is difficult to remove and will be noticeable after reattaching the faceplate.

To clean the "grunge" from the faceplate, I've used alcohol or a mild diluted soap cleaner. Avoid any strong solvent since it may damage the plastic or lift the lettering. Cleaning tends to involve several hours of cautious scrubbing for good results.

BTW since the deposits are generally mostly organic material, a touch of saliva works well too
