Here's some pics.  As you can see it bleached well along the bottom. What you said makes sense though.

I think I would have continued bleaching, but judging by pictures is hard.
Seems odd that there are a couple of streaks that look they bleached better, almost as if a stream of liquid ran down there.
Bleaching with Chlorox is definitely not as potent as peroxide, it does take longer.

This phone took at least 20 hours in the solution.

Hmm perhaps I should try sticking it in again, but all in all that housing spent about a total of 15 hours soaking. I would've expected to see even results by that point. Interestingly enough where those lighter lines are the outline of the ribs on the inside of the housing .

There are actually many posts in this forum that deal with that subject matter.
See for example here for a restoration of an ivory set using Clorox bleach.

Here's another using the retrobrite process.  http://www.classicrotaryphones.com/forum/index.php?topic=1146.0

What you show in your pictures looks like what I got before I started using the creme formula. I figured it was from uneven application and exposure. Follow Unbeldi's advice, turn frequently and keep the solution mixed. That should yield better results.

Is bleaching ABS housings a no no? I've not found any mention of that and have only seen postings about bleaching the soft plastic. I took a severely discolored Ivory 500 housing from 1979 and dipped it in a strong bleach solution overnight to have it come out blotchy. The bottom of the housing around the edges is back to original color while there's still cow patches of yellow over the plastic.
This was my first attempt at restoring color and I wanna get this right before I go to work on my pink 1967 1500.

Two different things here.  Chemical restoration of yellowed white phones is a different method and process from restoring colored phones.  White phones may take several applications to restore them to white.  I used the retrobrite process with success, but it took 4 applications.

Bleaching colored phones has not worked well.  Forum member Phonesrfun tried bleaching on a blue phone without success (I can't find the thread, it's here somewhere).  Instead, see this thread about a product called White Magic that worked well restoring a turquoise AE90.  I have not yet used it on a colored phone, but it worked well when I tried it on a white receiver cap.  Problem is it's not found in the US, only in Canada.
