I haven't my last job using a spray gun was could years ago painting the outside of a house. Just use it to clean up my messes and the brushes does a super job. I had these bedroom doors that were stainned and I sprayed Cln1 on them omg the grease and grim just dripped down the door, it's a great all purpose cleaner. My favorite is Winning Colours man that stuff is strong cleans anything.
