Removal request for entire catalog. Can be done without blocking in robots?

[LocalLocal]

Bunch of thin content (catalog) pages modified with "follow, noindex" few weeks ago. Site completely re-crawled and related cache shows that these pages were not indexed again. So it's good I suppose

But all of them are still in main Google index and shows up from time to time in SERPs. Will they eventually disappear or we need to submit removal request?Problem is we really don't want to add this pages into robots.txt (they are passing link juice down below to product pages)Thanks!

If your intention is to keep the page for "follow" I would not submit a removal request for the page since that will wipe it off the map. Google needs to crawl your page to know you don't want it indexed.

Things can take a while, sometimes many months before its not indexed properly. Google also has a disclaimer that it could possibly keep the page indexed for a while.

Also you have to make sure that you do some post things after the removal is made to ensure it never comes back

As I said, Google already re-crawled them and they are not re-indexed. Last cache dates show all is correctly lef out of  new indexation.

I guess my concern was how long this pages will stay in index. That was done to make sure Panda will be able to recalculate the value of the site.
