I bought this along with 3 in 1 oil to clean the rusty spots on some old chrome rods I have and it has done an amazing job I think the steel brush bristles are better for rusty iron scales but when it comes to chrome bars or rods I think this brass brush along with 3 in 1 oil is better for this as some of the old bars I have almost brand new now even though they used to look damn rusty Worked perfectly for me and definitely worth the money.
