Step 4: Gawp at the Results.

I was really blown away. In some of the pictures the flash makes it look more scratchy than it really is. I don't think I'd use this on a top dollar bike, but I hope a top dollar bike would have better chrome (and better care).
<p>Well, I own 6 motorcycles. Every one of them was an anchor when I got it. I restore old motorcycles for fun. </p><p>Get three empty gallon plastic milk jugs. Go to Tractor Supply. Get yourself a gallon of &quot;Milk Stone Remover.&quot; osts about 5 bucks. Dump it into a wide plastic bin, with three gallons of water. place your rusty item into the diluted acid. If you leave it in the solution for 6-8 hours, the rust is gone. Your part is clean, derusted, and rust resistant. I swear, you can take your fingertip, and wipe off the oxidation. When you're done, put it back in the jugs for next time. I have acid that is 10 years old. Still works. After several uses, it forms crystals which you can skim off and throw away. </p><p>One thing, Do not use Muratic Acid. It also works well, but you will instantly flash rust. There is a good chemical reason for this, but I won't get into it. Incidentally, the chemical in the Diet Coke is an EXTREMELY diluted phosphoric acid. That's why you have to scrub. Aluminum foil WILL lightly scratch light chrome. Period.</p>
<p>PS When you're done, rinse the part with water. You get zero flash rust.</p>
so just scrub with Dt. Pepsi and Aluminum foil? That sounds to easy, whats the catch?
The catch is that i will rust immediately when it comes in contact with water.<br /> Those spots that rust, are pinholes in the chrome coat. By this or other polishing methods you remove the rust and then you you have the bare steel on the surface. You'd need to clear coat it, but there are not too many clear coats, that can handle high temps on exhaust pipes.<br /> <br />
<p>There has been, for years, products that would take a rusty surface and convert the rust. The common chemical is phosphoric acid. It is also what makes this coke trick work, too, because it has a little phosphoric acid in it...makes it tangy. It is just so diluted that it has limited action in converting rust. The product, &quot;Milk Stone Remover&quot; is actually pure phosphoric acid. It's called that because it is used to clean the calcification in milk processing equipment. It is also dandy for rust.</p>
When you remove rust with phosphoric acid, you are converting it to a compound with a single oxygen atom. It's black, and inhibits rust. Unless the pits are severe, it won't rrust easily
Like I said in the Instructable, the chrome wasn't great from the start. Of course the rust is coming from microscopic holes in the chrome. It's not very helpful to say to clear coat it, but then say clear coat won't hold up (it won't).<br /> <br /> As with any polished metal, the answer is to simply keep after it. This method works well, quickly and cheaply.<br /> <br /> <br />
There are other chrome plated parts that don't get hot... it may be helpful for that.<br />
Hi Temp engine paint is available in colors, shines nicely, and gives a custom touch (black for eggsample)<br />
But then it wouldn't be... chrome.<br />
Why no, it wouldn't be. But, given the choice between shiny slightly scratched chrome and a color which looked custom, I think I'll take the color.<br /> <br />
that's how we did it up az\t the gm plant in tarrytown, ny., to the hundreds of cars sitting in inventory. (in the 60's)&nbsp;
<p>Brasso is for soft, unitary metals, like Silver, Brass, copper, etc. Not chromed metal.</p>
<p>Brasso is great for one time use. It is mildly abrasive, however, like Soft Scrub. If you use it once a month, you can get rid of all of your chrome by the end of the summer!</p><p>All you have to do to take care of chrome is to un-rust it with a good non-abrasive cleaner, like Nevr-Dull wadding. You get it at Auto Zone. Then a good chrome polish (maybe Meguilars?) every now and then. It prevents oxidation (rust.) Only use cotton to clean or polish, like old tee shirts, or my favorite - old towels.</p>
<p>You can also use electrolysis, which doesn't cost a dime, requires no scrubbing, and delivers a beautiful result. It does flash rust, however. And make sure that you have the polarity correct, or you will remove the chrome!</p><p>Maybe I should do an Instructable.</p>
<p>Most of search because we want to find ways we havent thought of and hopefully that someone has actually practiced what they are saying. That gives us a better platform to make a decision on than just opinion alone. Because opinions are like noses - pick one. :-)</p>
<p>Thank you Captain Pedantic. Yours is a helpful and inexpensive method and you mention the caution for new chrome. Which hopefully, wont be in that pcondition anyway. The rest of you guys are no doubt brilliant and OCB, perfectionists but if you dont have something good to say - dont say anything at all. Captain - keep up the good work and thanks for sharing.</p>
I have a 1975 Honda Goldwing GL1000 with a LOT of chrome, and the very best thing I have ever used is a product called &quot;Brasso&quot;. It is a liquid, but also comes in a paste. It works on EVERY kind of metal.<br>
Always used a combination of Brasso, Autosol and Elbow grease... and worked well on all the Wing's from 76 thru to present... in fact, brasso is smooth enough (not that abrasive) that it can be used to polish the frame etc!<br><br> However, i was introduced to a product recently (the name of which evades me at the moment - I'll check back when i remember!) which put all of those to shame. It was test proven to me on a REALLY rusty bin, literally a splash of this stuff and 3 minutes buffing with a bit of jean material and this thing shone... I mean, really shone, I never seen a bin shine quite like it. Tried it on my stained and pitted GSX400T casing and it came up SHINY, for the first time since I've owned it, and it only took about 10 minutes to do the hole case!
what is name of that last product you mentioned?
I think he was talking about a product called &quot;BLUE JOB&quot; chrome polish/cleaner.<br>it is a powder, you can add water to make a paste, and polish with a piece of jean material. It is very expensive in my opinion.<br><br>
fast orange works well to
To protect the restored shiny chrome carefully spray with your favorite lubricating oil spray and then polish with an old cloth. This leaves a protective film on the metal which repels water. This is good for cleaning, polishing and protecting<br>and only takes a few moments effort every time you clean the motorcycle<br>to keep it looking good.
OK I have tried this before with just soap and water and aluminum foil. I didn't use the cola. the foil rubs off the rust and polishes the chrome or rather the foil particles fill in the rust spots and polishes to a sheen. after doing this it is a good idea to either clear coat or wax to protect the new finish.
both clear coat or wax wouldn't last the heat of the exhaust pipe, unless there's some high temp clear coat i haven't heard of...
i have been riding an orange cb 350 but im moving up to a cb 750 with a windjammer
Great Im gonna try this on my Monkey bike.<br />
I own a pristine 1972 Honda 350.. Great work on your Instructable
i did this with my dad's bike before he (my dad)&nbsp;sold it and the buyer was really impressed (he left $100 more) and now with the money we may just buy ourselves an iMac - know the best model to buy?<br /> <br /> Great Instructable
Odd thing about cola, it contains phosphoric acid. Other sodas don't. FYI: much stronger phosphoric acid can be purchased at the auto parts store for about as much as a three liter coke. It also works wonders on non chromed rusty metals.
I've used Ospho (a phosphoric acid surface prep) for other purposes, but I'd say it's hard to beat two liters for 54 cents!
PH down for hydroponics is also phosphoric acid and a much more concentrated solution as well. Its possible to mix it with polymers to create a gel that sticks to things.<br />
The phosphoric acid in the cola is what does the trick. I have used regular cola without the foil on engine parts. The sugar helps hold the phosphoric acid onto the parts while soaking. After seeing what cola can do to rust you may want to try&nbsp;<a href="http://www.instructables.com/id/Homemade-Carbonated-Beverages/">www.instructables.com/id/Homemade-Carbonated-Beverages/</a>
Diet cola has no sugar... :)<br /> <br /> and it would be the Carbonic acid you are referring to.<br />
&nbsp;I was referring to what I was taught, that the sugar in <em>regular</em> cola helps hold the <strong>phosphoric acid </strong>to the parts your cleaning. Carbonic acid does nothing to rust. We sell dedicated rust removers that are phosphoric acid. If you read the ingredient list on most commercial colas,&nbsp;<strong>Phosphoric acid</strong> is right there.&nbsp;
You might want to read the ingredients on cola some time...<br /> Carbonic is a very weak acid, the phosphoric acid makes the cola &quot;tart&quot;.<br /> Pepsi has citric acid as an added ingredient...<br />
