I am contacting you to ask for some assistance regarding the DeoxIT® D5 and DeoxIT® F5 products you sell.
In short, I am a musician in need of repairing my Fender Stratocaster guitar. The volume knob on my guitar is very crackly when being turned so I took it to the repair shop and they used Servisol. I thought they had repaired it but unfortunately the problem returned very quickly and the volume knob now also feels a bit stiff compared to how it used to feel.
I want to give repairing it a shot myself and I continually read your products are the best for this job. Evidently the pot needs both cleaning and lubricating and both of the above products do this. However, I am unsure of which of the two above products I should use for this job.
With regards to cleaning and lubricating the volume knob on my guitar, should I be using the DeoxIT® D5 spray or the DeoxIT® F5 spray?
