Help about nasal cleaning?

Since I've been congested for the past week,I decided to use a similar Neti pot technique(not exactly the same)So i added about 1 teaspoon of iodized salt(i know its WAY too much!and its not the right salt)But i only found out later.Afterwards,i flushed my nose with fresh warm water to try and get all the remaining salt water out.My question is,Is there a certain risk of salt water being left over,and later on evaporating in my sinuses ? and please no rude comments
