Hey guys I did a search and couldn’t find anything and I hope I am posting this in the correct area I am new to the site. I was running my BCM pretty hard the other day and got sand everywhere because I live in New Mexico. After wiping down the BCM I had some stubborn sand left over so I hit it with solvent and wiped it off with a high quality white undershirt. After the lower dried I noticed some strange spots on my lower. I will include a picture, can anyone tell me what they are and how to get rid of them? Due to the environment I live in I would like to avoid using oil if I can. I understand this is cosmetic but they bother me.
I don’t see anything. Wipe it down with a lightly oiled or silicone cloth and see if you like it.

I had a finish problem once on a factory built rifle, I contacted the mfg. and they took care of it. It’s probably a problem with the anodizing not being done quite right, at least it was with mine. Email BCM, I’m sure they will take care of it.
This. The first time I hosed down a lower with brake cleaner I almost cried. It’s just the finish dried out, hit it with a silicon cloth and follow up with another clean cloth to remove excess.
I’ll agree with the others… Most anodized parts look dry when the are dry. I understand not wanting oil but have you thought a dry lube? I have had good luck with motorcycle chain lube to protect without being wet. Dupont chain saver can be found a Walmart.
Like said above just put some lube on it. You should have seen my face when I sonic cleaned 12 Colt SMG lowers. I took them out and put them on a rack to dry and when I came back they looked white. I though I had baked the finish off. After I hosed them down with CLP they looked fine again. David
I don’t see anything either…
Light oil, wipe off excess. Sandy environment shouldn’t matter.
i live in southern New Mexico and shoot a lot, all conditions. do not be afraid of oil, heck the more oil the better. that dust sand and grime need something to cling to that will carry it away from moving parts. the only time i don’t oil heavily is in extreme cold when visiting friends in Co.
Both pics show a nice finished receiver. Don’t put anything on it-leave as is.
Looks good to me. Now go shoot it and have some fun!
If I had a lower that looked that pristine , I’d think I was neglecting it.
