Once you have selected the candidate base body, give it a thorough cleaning, removing the manufacturer's oil and powder, and any grime, dust or lose particles. Careful washing with soap and water, and then scrubbing with something slightly abrasive like fine sandpaper or a toothbrush will do the job. Be sure to give the crevices a good cleaning, as well, to assure that your customized homelander figure accessories and features, as well as the paint, will adhere properly. When working in the sink, be sure to securely cover all the holes so that any loose parts cannot stray and disappear down the drain with the running water.

After washing, prepare the base body, removing unwanted accessories and features with pliers, wire cutters, an X-acto knife, and a Dremel power tool with attachments, as appropriate. You may need to soften areas of the body to ease this step. Run hot water over the body for 30 to 60 seconds to help make it softer and more pliable. You may repeat the hot water treatment as often as needed while you modify the base body. A nail buffer or very fine sand paper can be used to smooth and finish the body.
