I tried to get silicone grease for my CD player recently - to help the
transport by greasing the 'rails'. However my tube (Servisol 50g at
£5.99 from an independent DIY source in Dorchester)seems not to
lubricate as well as previous samples. Indeed it seems to make the
movement stiffer! Are there different 'grades' of silicone grease and
does anyone know what I should be using for this task?
