How to properly clean a nozzle?

Nozzle blockages might occur in occasions when the filtering system’s ability is insufficient, or when nozzle’s flow rate is relatively low. In order to avoid these, the nozzles should be routinely cleaned, per the following instructions: 
1. The most effective cleaning method utilized to avoid damaging the nozzle is compressed air. The air should be blown from the nozzle’s spray orifice towards the water inlet.

2. In cases of severe blockages in plastic nozzles, the nozzle should first be soaked in a diluted, low-density hydrochloric acid, then washed in water, and lastly blown on using compressed air to remove any unwanted objects that may have remained. Avoid using high-density, highly-concentrated hydrochloric acid or any other similar chemicals to avoid damaging the nozzle.
3. When attempting to clean blocked nozzles, absolutely refrain from using hard or sharp objects to remove the blockage, because the nozzle orifice’s surface and structure might get damaged, what will highly influence the nozzle’s spray quality: the spray capacity might increase or decrease, the spray pressure might become insufficient, or the spray shape might change. All these may influence the spray coverage area or lead to a stronger water jet, what may cause the liquid distribution to greatly alter.
