Old toothbrush and washing up liquid - pour some onto the shaft and give it s good clean all in the tracks. If you have tarnish on the shaft I use Autosol chrome cleaner paste - put a small amount on a tissue and remove the tarnish. Do this before washing with the toothbrush.
Allow to drain and dry (I use a hair dryer). Using a pencil, I push a small ball of tissue through the shaft centre to make sure its clean. Same process with the draw and pins.
The sleeve, I use WD40 and a soft polishing cloth (try to keep the label at 12 o'clock to ensure the spring does not come out. use your nail (yuk) or a cocktail stick between the outer sleeve grooves before the WD40.
Next push a wad of tissue through the centre. I then use 3-in-1 bike oil inside the sleeve place a small drip on both ends. Use your finger to spread the oil inside the sleeve and then pass the wad through again to ensure not too much oil is left on.
Once dry, reassemble the shaft as per instructions (if you wish to add a drop of oil, I suggest the drop goes in the first entrance. Once assembled - quick polish on the sleeve and you puzzle is as good as new
