Vintage Synth Repair

Hi, No offence but that's just BS, Deoxit works perfect, and has no side 
effects what's so ever. Your telling a guy who does not even know how to 
clean his sliders to take the sliders completly out dismantle them  and clean 
them out individually..?? please.... Yea, Maybe if they need complete 
restoration and you can't find ones on the net for 10 dollars apiece... how 
many sliders are ther????.Long term use, they have been around 30 years 
already....Help the guy don't confuse him....
