Soda blasting uses an air compressor and baking soda to safely and gently blast away paint or rust. Use an air compressor with a tank of 25 gallons or more and a flow of at least 6 cubic feet per minute (CFM). The compressor's air pressure should be set to around 80 to 90 psi. Perform the blasting in an open, well-ventilated area to facilitate easy cleanup.
Roll out a length of the vinyl hose. Measure a 2 foot segment of the hose and mark the spot with your marker. Use the knife to cut through the mark, but don't pass all the way through the hose. You want one side to stay attached to the roll.
Put the tip of the air gun attachment into the hole in the hose. Let the tip stick out about 1/2 inch.
Wrap together the attachment tip and the hose, using tape to keep them from separating during the blasting.
Cut the end piece at--the other end of the hose, the furthest from the air gun attachment--at a 45-degree angle. Strengthen this part of the hose by taping a wooden dowel along its end section.
Open the top of a box of baking soda and place the dowel end of the hose deep into the box.
Hook up the air gun attachment to the air compressor. Power on the compressor. Start using your soda blaster for your cleaning project.
