Modifying _msdcs.domain.local

I noticed under _msdcs.domain.local > dc and gc > sites I have old data. Is it safe to manually remove these old unused sites? Why isn't this removed automatically?
I just want to  make sure that it isn't interfering with my current set up in Sites and Services.

Are you saying that there are old sites in the zone, or old SRV records?  In general a clean demotion of a dc will also remove its records in the _msdcs zone.  In fact, if you delete the _msdcs zone and create a new one, all the records in it should be autopopulated by the DCs when their Netlogon service restarts.  Also, when a site is deleted from AD Site and Services it should be removed from the _msdcs zone automatically.

Yes, the sites that I deleted were not removed automatically. I am not demoting any DC just browsed through there and noticed those old sites still in there. The timestamp is old so I am just wondering if it is safe to remove or indicative that something else may be wrong since it didn't automatically remove.

I'd say both: if those sites no longer exist, the corresponding records can be removed from DNS...but because they weren't automatically removed when the sites were deleted, there could be a problem somewhere.

I removed manually but scavenging was not set up on this zone.
Thanks!
