Brass cleaner, but it's a big job. I suggest you go to a large Hardware store and ask them. There are sprays for crystal chandeliers, so you may get lucky and there is one for brass. If not, then see a light dealer and ask them what spray you could use to seal in the shine (after you have cleaned the brass chandelier). Most brass now has a sealant so you don't have to keep cleaning it.
Natural would be, half of a lemon and table salt, combined with elbow grease.
One can clean a brass table lamp by: applying rubbing alcohol (Isopropyl) to a light sponge and rubbing it against the lamp. Then wipe the lamp with the yellow cloth that came with the alcohol to polish it.
The best way to clean a glass chandelier is to first make sure the power to the chandelier is turned off. If the chandelier is high off the ground, a ladder will be needed. With the ground covered in sheets, it is best to use ammonia to clean the glass.
Assuming you mean, are the words "clean those brass" adjectives, the answer is no, maybe, and yes Clean is a verb. Those is a demonstrative pronoun. (Some people might call this a form of adjective, as it is a modifier.) Brass is an adjective: a brass trumpet, a brass bookend. Note that brass is also a noun in some uses: the brass on that uniform is shiny, the brass in this orchestra is very good
Disconnect the chandelier from the power supply. Place a thick blanket on the floor under the fixture, which will soften the fall should you accidentally drop a crystal prism. Climb the stepladder and remove all the bulbs in the chandelier that can be removed without using tools. Clean in sections. Carefully remove the crystals from a section of the chandelier, and place them on the first towel. Wipe and buff the frame. Reassemble the fixture, being careful not to twist the chandelier too much, since doing this can loosen it from the ceiling.
Since a wrought iron chandelier usually has many intricacies, it is best to wipe it down with warm soapy water and a dishcloth. Make sure to use a dish soap that has a degreasing agent, as this will clean better.
You can clean a brass telescope. Over a duration of time, brass starts to oxidize. To remove this, can use vinegar and salt. You can also use a concoction of chemicals that is premade, usually by a company that specializes in brass.
When crystal white chandelier lighting holds onto its sparkle, it more than lights up a room, it livens it up. But the reverse is true as well. When crystal white chandelier lighting is allowed to grow dull, it can quickly make a room look lifeless. To keep from sapping the life out of a room with white chandelier lighting overhead, give it a good cleaning every 3-6 months. Lay down a drop cloth beneath the chandelier to keep from getting dirt, dust, and cleanser on your floors. Any bulbs on the white chandelier lighting that are pointing upwards need to be covered before you start any cleaning. You can use a sock, plastic wrap, or sandwich bags secured with rubber bands. As a cleaning solution, you can either purchase a cleanser that says on the label it's safe to use on chandeliers. Make sure you don't use anything that contains ammonia, however, as that can degrade the finish on the framing. To make your own white chandelier lighting cleaning solution, just mix 3 parts distilled water with 1 part rubbing alcohol. Pour it into a spray bottle for easiest application. This is particularly important if, as is very likely the case, you will be climbing a stepladder in order to reach the white chandelier lighting so you can clean it. If this is not comfortable for you, then it might be worth considering hiring a professional to come in and clean your white chandelier lighting for you. Apply the cleaning solution to a soft cleaning cotton towel and wipe it onto the crystals on the chandelier one at a time. Do not spray the chandelier directly. After cleaning all of the crystals this way, next you want to polish the framing. Usually the framing is made of brass or some other sort of metal, which can be cleaned using the same method with brass or metal polish (and a different towel). After you've finished cleaning, don't forget to remove the coverings from all of the light bulbs before you turn the white chandelier lighting back on. Crystal white chandelier lighting can make any room look like a million bucks, as long as it's kept shiny and clean.
Use WD-40
