A good old pink eraser works great for removing sharpie ink.
However phone companies quit using 66 blocks long ago because they are proned to connection failures. Some use 110 blocks, most use wire-wrap type, which is the best IMO.
Pink eraser- maybe if it isn't too old but most of the stuff we get has been there for years. I suppose too that the material and surface matter a lot.
66 blocks are still more popular than 110 around here. Easy to attach test clips to.
Also popular are Krone blocks. These are usually used for a demark since they incorporate built in contacts that bridge the two sides. They are nice because a test plug will interrupt the bridging and bring both sides out to the test leads so you can isolate a problem to one side or the other. Only problem is that sometimes the contacts get dirty and cause problems.
Only place I have seen wire wrap is in the CO or large frames with CO type protectors.
