Can i wash my hands with soap while wearing sterling silver

Washing your hands using soap with the ring on should not be a problem. 

but rings can slip off during the washing of your hands if it is not an exact fit and soap can build up under the ring and cause a rash on your finger 

If you value the ring, taking it off when washing your hands would be safer 

Yes it should be effective but can cause a rash so safer to take off

Since you provide no further choice,

One of the reasons is because he know that Halima must has a very important reason to risk her children's live on such dangerous trip, which built up his protective feelings toward them

hope this helps
