Cleaning up transaction replication del/ins/upd stored procedures? I'm referring to the ones that start with:

dbo.sp_MSdel...
dbo.sp_MSins...
dbo.sp_MSupd...  

I've noticed they are not removed when I run exec sp_dropsubscription on the Publisher then run sp_removedbreplication on the subscriber (on the database).  I also tried sp_subscription_cleanup to no avail.

Do these have to be deleted manually if I want them removed?

Subscriber is SQL 2000
Publisher is SQL 2008 (Distribution database is on the Publisher)
When you remove a subscription nothing is done to the subscriber.  You'll need to remove these procedures manually.  They are safe to remove is replication has been removed.
