How do you clean dry battery acid from a carpet?

Could there be hidden damage from battery acid on carpet?

• Answer:

  Hello, I recently spilled a small amount of battery acid from a 5 year old battery as I was transporting it. I didn't think anything at the time as there was no smell. I threw away everything that it got on and cloth cleaned the area. Then the acid smell started to come and get bad over the next days. The carpet itself is not damaged or have appearance of damage. I used a mild cleaner to clean the carpet well and the smell is still there, but still no visible damage-should I just leave it and let it dry? Or remove it completely in the event there may be hidden damage, I certainly don't want to start corroding the metal underneath and the smell is getting less each day. So any thoughts on this? Thanks
