Castello White Stem Cleaning Question

[iajaffe]

I have a Castello with a white stem and it is beautiful. Smokes fantastic too. My question is how to keep the airway in the stem from showing through. It looks like I have a dirty strip along the center of the stem from the outside. I have tried Everclear and pipe cleaner (fluffy, tapered and bristle), but it still shows.
I know the stem is acrylic...can I bleach it? Will that affect the black dot?

This is why I stopped using white for stems.

Soaking acrylic in pure alcohol will likely result in it cracking/crazing.
Try a bristle cleaner and some soap first.

I have a couple of GBD Prehistoric pipes with clear Perspex stems that get pretty bad and Soft Scrub works really well.
Here's an article I found about it:
