Default Ignition Shielding Clean Up - Surface Rust

I have pulled the ignition shielding and was wondering what you guys would suggest to clean up the surface rust to polish it out. Scotchbright, steel wool, polishes?

Also I am trying to pull the mounts these bolt to, light blue mounts in 2nd photo. The drivers side is accessible but the passenger side looks like I will have to pull the distributor to access it. It seems like it would be easy to get to, I can see it and access it somewhat, but all the tools I have tried are not working on getting a grip on the bolt head. Maybe there is a magic tool combination I am not using someone will know of. I plan on pulling the distributor but was not quite ready to dive into it yet as I am waiting on parts for the current "While I am here" on the differential, this was to just be a small project to do to keep the motivation going while waiting.

SOS pad or other steel wool type. Don't over think this.

Try this , it's easy and does a pretty good job! Both of these valve covers looked like the top one when I started! When I finished they both looked like the bottom one!
can be done by hand with a soft cloth or a three inch polishing pad on a small air angle grinder !





PS almost forgot , the only place you can buy this stuff is Lowes !

ScotchBrite is a No-No in my book. Wash them well first to get any loose grit, etc. off so that you don't just scratch it up with surface junk. Steel wool [#0000] works well and will not scratch chrome. If you have small pits/scratches that are no longer covered by chrome, you can try rolling up a 'ball' of aluminum foil and rubbing it into the surface of the part. That will cause some aluminum particles to fill those areas of chrome loss and "hide" that loss fairly well (for a period of time).

Whatever you do, when done, give the part a good coat of chrome polish or hard wax/polish to protect it from the stuff it experiences in your engine compartment.

Thanks, will get some steel wool and diamond bright and give it a try. I degreased them and hit them with the tin foil and water and at least they are smooth and 70% of it cleaned up, hopefully after the steel wool and polish they will look A++. I am going to pull the spark plug shields and lower v shields tomorrow to clean them up also. The spark plugs were changed the other day and have new wires that have not been put on yet so will do that while I have the brackets off, old school routing. I am going to get some new bolts and wingnuts while at lowes, think they are 1/4 20, and should have everything in the set.

I looked at these sets online and they range from $400 - $500 for uppers and lowers so consider this a $450 elbow grease upgrade for the price of some bolts, wool, and polish. It helps me offset the $ I am spending on the drive line, mentally anyway.

Use of any abrasive WILL scratch chrome plating. At our local Peterbuilt dealership I picked up some metal polish just like SPCL FX states, it requires a lot of elbow grease but does a very good job, it also polishes up aluminum. T

I use Brillo pads. It does a nice job of removing light surface corrosion. Chrome plating is very hard and durable stuff. I never have a concern about the steel in the Brillo scratching it and haven't seen that it leaves any scratches behind after cleaning.

I would worry about the thin cheapie factory flash chrome finish being really delicate. Simple green wash followed by a white vinegar soak would be my first try.
