Does touching something that has been afflicted by urine, then dried and its trace removed, then wet with water, affect its purity?

An object upon which urine has fallen remains impure (najis) even if the urine dries and no trace of it is visible. The ruling of impurity is not removed except by purifying it with water. Therefore, if water touches a spot that was affected by urine and then dried, everything that comes into contact with this wetness becomes impure.
