Chrome plating is process by which a sparse layer of chromium is applied to a metal surface through electroplating (normally on top of a layer of nickel). The ultra-shiny results are decorative, corrosion and tarnish resistant, and very durable. Withal, chrome plating is routinely removed for many reasons. For instance, despite the durability of chrome plating, it tin be damaged through wear and tear and become unsightly, requiring removal. A diversity of options are available for removing chrome, some of which apply mutual everyday materials and others which apply highly toxic chemical solutions - whichever method you cull, use all necessary caution and notice relevant prophylactic protocols.

1. one

   Use an annoying blaster. Annoying blasting (e.one thousand., sand blasting, dewdrop diggings, etc.) is a procedure by which materials are abraded with a spray of fine-grain powder or tiny pellets. Often, machine body shops and construction companies will take admission to such devices. Prolonged abrasive diggings can remove an object's chrome finish, though bear on-upwardly work may need to be washed on the object's difficult-to-reach areas afterwords.

   • Yous may want to employ a relatively fine-grain medium (for instance, 400-grit sand) when diggings your chrome to forbid damage to the underlying metal.
   • Annotation that the airborne dust and sediment produced by chipping off tiny pieces of chrome while using an abrasive equalizer can exist toxic, so utilise appropriate face/mouth protection.

2. 2

   Use an ultrasonic cleaner. Ultrasonic cleaners are special devices that use sound waves to clean delicate, hard-to-clean items like jewelry. Ultrasonic cleaners tin fifty-fifty remove chrome in some situations (especially when the chrome has already been loosened with another method). Place chrome items in the ultrasonic cleaner'southward basket and submerge them in a cleaning solution (often ordinary water), then let the cleaner to run according to its instructions.

   • Using a solvent that tin deliquesce chrome (for instance, bleach, as noted above) rather than water can heighten the chrome-removing power of an ultrasonic cleaner. However, only do so if the solution you lot employ will non corrode the cleaner or otherwise react with it in whatsoever fashion. For instance, equally noted beneath, lye will react with aluminum containers.
   • Annotation that, while ultrasound machines come in a variety of sizes, nigh volition merely concur relatively small items, such every bit jewelry, lug-nuts, tools, ornaments, etc.

1. one

   Apply muriatic acid (muriatic acid). Hydrochloric, or muriatic, acrid, is a strong, corrosive acid. In high concentrations, information technology tin can be used to remove chrome plating from metallic objects. For removing chrome, an acid solution of about 30-xl% concentration should suffice.^[1] Go along every bit beneath:

   • Mix ane/3 part hydrochloric acid to 1 office water in a vat used for chemical mixtures (similar a heavy-duty plastic bucket, etc.) to produce a xxx% acid solution. Alternatively, purchase a pre-mixed acid solution of sufficient concentration.
   • Submerge the chrome-plated object in the solution until chrome strips off.
   • Launder the object thoroughly in soap and water, and rinse before drying.

2. ii

   Use sodium hydroxide (lye) to strip chrome from ferrous metals and carbon steel. Sodium hydroxide, commonly chosen lye, is a caustic, highly basic chemical.^[2] It tin can dissolve several types of metallic plating, including chrome, just reacts dangerously with water and aluminum, corroding the aluminum itself and producing flammable hydrogen gas. Thus, it should but exist used on items that do not use aluminum every bit a base material. Proceed as below:

   • Mix 8 to 12 fl ounces (about 227 ml to 355 ml) of sodium hydroxide with 1 gallon (3.785 L) of water in a vat made of neutral material (like a heavy-duty plastic bucket).
   • Soak the chrome-plated object in solution until chrome comes off. This may take a fairly long time, so frequently check on your item's progress.
   • Wash the object thoroughly in soap and water, and rinse before drying.

3. 3

   Perform a reverse electroplating. Chrome is affixed to metal through the process of electroplating, in which electric current is used to bind chrome to the metal at a molecular level. By reversing this procedure, chrome plating tin be removed extremely effectively. However, doing so can be extremely unsafe. Not only does the process involve a live electric current, but as well produces several toxic, carcinogenic chemicals as products of the reaction. Hexavalent chromium, for example, is one extremely dangerous production.^[3] Thus, this procedure is best left to professionals - the steps below are for informative purposes simply.

   • Mix chromic acid and sulfuric acrid in water in an approximately 100:i ratio. For example, you may add together 33 oz. (936 grams) of chromic acrid crystals and .33 oz. (9.36 milliliter) of sulfuric acid fluid to distilled water to make one gallon (3.79 liter). Mix solution in a proper immersion tank used for electroplating, materials testing, and/or chemical treatments.
   • Heat the solution. Keep the temperature of the solution from 95 to 115 degrees Fahrenheit (35 to 46 degrees Celsius) for decorative chrome. Proceed temperature from 120 to 150 degrees Fahrenheit (49 to 66 degrees Celsius) for difficult chrome.
   • Run a negative charge from a DC power source through the chromic plating solution via wire.
   • Adhere the positive cathode to object intended for stripping and submerge the object into the solution. The positively charged exterior chrome metallic will be pulled from the object.
   • Rinse object in agitating running water, and so rinse again. Accept waste products professionally processed and disposed of.

1. 1

   Use a homemade abrasive to remove particularly sparse or weak chrome. One of the simplest, most beginner-friendly ways to remove chrome is via simple mechanical action - i.e., scrubbing with an abrasive. Mix baking soda or a solid household cleanser with h2o to brand an abrasive paste that can be rubbed onto the chrome with a soft cloth until the chrome begins to requite mode. This method may work best with specially thin, weak chrome plating or with "fake" chrome plating (for example, plastic painted with a fake "chrome" material). Fifty-fifty in these cases, considerable elbow grease may exist required.

   • Bank check your progress ofttimes as you scrub. Scrubbing for too long may scratch the underlying material.

2. 2

   Apply oven cleaner. Some types of chrome (especially faux plastic variants like you may find on model cars, etc.) tin can be removed with commercial-grade oven cleaners. These powerful de-greasing solutions usually come in an aerosol can as a cream or liquid spray. Give your chrome role a generous blanket of cleaner, then allow information technology to sit down for 10 minutes. Wipe the chrome off along with the spray-cleaner.^[iv]

   • Note that some oven spray-cleaner may darken any underlying metal if left to sit down too long, then yous may desire to apply the procedure repeatedly in brusque increments until you accept the result you want.

3. 3

   Soak the chromed particular in household bleach. ^[5] Another favorite method of model car enthusiasts for removing chrome is the use of a bleach bathroom. In this method, chromed parts are only submerged bleach and left to sit. After about a day, depending on its thickness, the chrome should be loosened if not stripped entirely.

   • The master do good of this method compared to the others is that bleach should leave whatever primer below the outer chrome layer intact.
   • After using bleach to remove chrome, it should be properly disposed of and never re-used (for laundry, etc.)

4. 4

   Utilize brake fluid to remove chrome plating. Standard automotive brake fluid works similar paint thinner to remove chrome layers from plastic objects. Withal, this method tin take several days to work. Additionally, it requires the proper treatment and disposal of the brake fluid, which is toxic. Rub the chrome object with brake fluid and allow information technology set about ten minutes before rinsing it off. Repeat as needed to completely strip the chrome.

   • Note that brake fluid tin can dissolve plastic, so be very cautious when using this method on chromed plastic parts (or opt for another method).

• Question

  How can I chrome plastic?

  

  Paint it with an electrically conductive paint. This is available on eBay under Jewelry Supplies. Spray it on with an airbrush to avoid brush marks. Leave 24 hours to harden, then it can be metal-plated with chrome, nickel, copper, gilded, etc.

• Question

  How does chrome plating protect steel?

  

  The chrome seals the steel from exposure to wet and oxygen, thus keeping it from oxidizing (rusting). Painting the steel has the same sealing effect, but chrome plating is thicker, harder, and more durable.

• Question

  Tin I weld chrome bullbar?

  

  Yeah, equally long as base material is weldable. Weld will not be corrosion-resistant unless a corrosion-resistant filler is used (stainless steel). Er309l type filler is recommended for walking stainless to carbon steels. Weld heat may discolor chrome.

• Question

  How do I find a place that removes chrome plating from guns?

  

  Reach out to one of your local gunsmiths. They will be able to aid you lot with whatever disassembly necessary as well as resources to strip or refinish your gun parts.

Article Summary X

One of the simplest ways to remove chrome plating is to spray information technology with a commercial-class oven cleaner. To practise and then, completely cover the chrome part with the cleaner and let it soak for 10 minutes. Then, wipe off the chrome and the cleaner and yous're washed. However, some cleaners tin darken the metal under the chrome if information technology sits for also long, and so you lot may want to utilise the cleaner in short increments to prevent that.
