Step 1
Remove the piece of chrome from its mounting. Most chrome pieces are either mounted with bolts and nuts or small clips.
Step 2
Lay an old towel, cloth, or piece of flexible silicone on a flat solid surface like a workbench, and place the chrome on that so the dent faces the protective cloth.
Step 3
Ask an assistant to steady and hold the chrome piece while you prepare to work out the dent from the inside.
Step 4
Place the flat end of a small wood block over the dent bulge. Gently strike an end of the block with a mallet or light-duty hammer a few times, and lift the wood to periodically examine the bulge.
Step 5
Repeat the hammering process as many times as needed to remove the dent. Some slight waviness in the chrome will remain, but the highly visible dent will be removed.
