I've got a handheld meter with a LCD display (Sunpro Tachometer) and
some of the LCD segments are getting flaky. Assuming it's put together
with a zebra strip, would I be better off trying to take it apart and
clean it, or wait until it becomes intolerable first? In other words,
what are the chances of making it better rather than worse?

?

I clean off the zebra and the LCD lands with methylated spirit and remount
with the zebra upside down. Unless the rubbery bits are perished/stuck to
the lands then unlikely to make matters worse.
