Never having heard of neti pots, I am posting this partly as a learning tool for myself, so please excuse any ignorant remarks. The following from Mayo Clinic. Fill the neti pot with warm salt water or ab over-the-counter saline nasal solution. Then tilt your head over the sink, place the spout of the neti pot in the upper nostril, and lift up the pot so that saline flows into your nose. The salt water will flow through your nasal cavity and out the lower nostril. Repeat on the other side. Solution- 1/8 teaspoon table salt into 8 ounces of warm (about body temperature) water.
Easier to use than a bulb syringe. Clean syringe or pot thoroughly to avoid bacteria. More effective than sprays.
