hey guys i recently came across a great metal polish for the chrome in my car .I was reading the instruction on the back of the bottle where it stated works for all metals , i took the polish and tried it on the back of my exhaust and what a difference it made . I watched the polished exhaust for 3 days and saw no sign of corrosion , now i'll let the pictures tall

ps- the exhaust was covered with castor and i straight away applied the polish (no washing or anything done prior to polishing)

After




The polish that i used was ABRO liquid metal polish
i bought it for 8 usd

raj, you can obtain better results on a muffler like that, by using Dawn Power Dissolver soap. Spray it on, let soak for 15 minutes, rinse off with cold water.

If you truly want that muffler to shine bright like a diamond, you will need to buff it smooth, and then use metal polish for the high lustre.

though sir this maybe out of context one of my friend used the crock pot method all of his varnish had gone kinda blackish we used the above polish and it gave back it color but not the factory one will the above stated soap work

I used the Dawn Power Dissolver on these and a few other motors. I like it better than the crockpot/antifreeze because it is easier and it doesn't require disassembly. It also doesn't turn black. It is hard to find, and may be impossible to get depending on the country you may be in. It smells and feels (kind of slimy) like BBQ or oven cleaner, which it may be. I brushed them a bit with a toothbrush, and the stubborn stuff with a brass toothbrush. The Fox had some silicon still stuck to it. After cleaning, rinsing with water, I sprayed it with oil, and ran it to make sure the water was out.

raj, Dawn Power Dissolver has never turned any parts black, in my experience. It has only turned them bright and clean. No heat is involved, only cold water is required.

Metal polish is great stuff too, it just requires a lot more work.

The crock pot method will turn aluminum dark if you get it too hot. If using the old green ethylene glycol and keeping it under 250 degrees, the metal comes out bright and clean. Using a brass brush or a stiff bristle brush helps on baked on castor.

I use Dawn Power Dissolver because I don't have a crockpot to use. Which is fine, because DPD works fine as is. I scrub with an old used regular toothbrush after 15-20 minutes and most often comes out looking really nice. I agree it is also nice to not have to disassemble the engine to clean it. If I couldn't find it locally, I'd order it online and ship it. I'm hardcore like that.

Wrights Copper Cream works real well to bring back the original finish/color. It's the copper in the alloy that turns and makes the finish look blotchy and uneven. Like Kmot says it just takes a little while longer.

Kmot, any new "Customs" in the works from your shop?....

I couldn't stop with it.

Wright's Copper Cream on the case and Mother's Billet Polish along with lots of brass brush scrubbing, files, bench stones and sandpaper on the muffler.

I take small items like mufflers and after a crock pot treatment, I use Jeweler's Rouge and buffing disk on my drill press and shine it up. And I am here to tell you it gets a high shine on it. Of course, good old Castor comes along and discolors it again. Yes, I do use Dawn Power cleaner but the crockpot works better for me.

What is nice about polishing is when it does come time to clean it, it cleans very easy. Making things smooth only takes one time and for certain things it pays off. That's what is nice about polishing smooth

Flyboy Dave used to first, use a soft wire wheel on the bench grinder for his mufflers. They have soft wire wheels right next to the regular or hard ones in the store. This is just a real quick way to get the large crud and castor off of mufflers. No, it doesn't scratch the aluminum with the soft wheel. Then he would use the buffing wheel and rouge for a mirror like finish.

You've got Dawn PD, antifreeze on low heat that does it all, and I'm very surprised at how well a sonic cleaner does. I put a Saito muffler that was blackened with castor in for a few 3 minute sonic iterations and it cleaned it down to the aluminum. Impressive! I like it for carbs because you don't have to worry about o rings. I use all 3 ways.
