It shouldn't really do any harm, but it may not be a permanent fix for a dodgy socket / very-oxidised pin. So may be better to see how long it keeps working for now / seeing if there is definitely a dodgy socket / cleaning suspected bad contacts IC's pins manually with some very fine wet & dry abrasive paper with some of that D5 sprayed on (or fibre cleaning block, but difficult to get to pins inside edge), until nice and shiny.
There was also a discussion on here about D5 a while ago: https://vintage-radio.net/forum/showthread.php?t=99254
