After that reconnect the paint gun with the turbine and hose and spray the solvent solution all over. Make sure that this process is done in an outdoor or well-ventilated area in order to prevent the inhalation of the solvent. The process is repeated till the solvent clears out all the paint residues. After completing the process use the damp cloth or rag to clean up all the parts and cup properly and also wipe down the lid as well.

Moreover, while cleaning the parts of the spray gun, make sure to clean the valve from the paint residue. Finally, the user will need to lose the fluid control knob and be careful not to lose the spring. With the help of a wrench, slowly free the nozzle at the front side of the spray gun.
