Some say to:
Try useing a small heat srink tube or a dab of hot melt glue over the end of the pipe cleaner wire
to avoid scratching the bore with the wire end. (All good ideas to try.)
Heat srink tube tryed.. fits threw wheel bore.. but look out while removeing it from bore.
Hot melt glue also tryed.. it's soft and wires can still push threw the dryed glue.
This got me to

On what else in the way of small tubes could be used as a fix for this problem.

Top tube: is a WD-40 straw tube.. way over sized to fit the wheel bore.
Bottom straw tubes..

Here's the fit:



Found it works ok for installing the pipe cleaner into the wheel bore..
But not so good for the removal of the pipe cleaner from the wheel bore if the straw tube is glued on.
Anyhow.. chime in on what you have tryed for your fix!
