>>I did a search on the archived forums and found that some tort keepers feel that it is not necessary to remove the tiny glochids, as they would be exposed to them in the wild anyway.

You got the major spines off I think the tiny leftovers won't cause problems but I don't have a redfoot, I have sulcata.
Our sulcata eats cactus too so I went to a local nursery & bought the spineless variety to plant in the yard. It has those little teensy spines too even though it's called spineless but I don't bother to take them off & it doesn't bother her.
