What is the best method for polishing amber?
487432
You will want to sand your amber with successively finer grades of silicon carbide sandpaper...Going from 220 grit to 400 grit to 600 grit using water to keep the stone cool...Polish with tripoli or tin oxide on a wet piece of leather

Start by using a damp rag to remove any dust or dirt.\n\nOnce it's relatively clean, you can use a metal polish on the knobs, hardware, tuners, etc. You can get a suitable metal polish at an automotive store.\n\nFor the frets, you can use steel wool (the non-soapy kind) to shine them. If you have a unfinished hardwood fingerboard, you can also buff the fingerboard with the steel wool. Don't be too aggressive with the steel wool - you don't want to wear things down, just polish them. NOTE: if you have a glossy finished fingerboard/neck, be very careful with steel wool - you'll need to use masking tape to protect the fingerboard.

Erm dont know if this will help at all, my wonderful fountain of knowledge (aka my wife) has suggested that you gently rub some baby oil on it, apparently it removes scratches from silver finishes and also cleans it, its certainly knowledge to me, but she normally surprises me with her vast amount random information.\nAlso nice and cheap, hope it works for you, and if it does please can you let me know.\n\nGood Luck

I advise my patients to use \n\nColgate Sensation Deep Clean Whitening\n\nThis has Bicarbonate of soda in it but does not have the strong taste that Arm and Hammer has.\n\nIt is very mildly abrasive, enough that it will remove staining but not damage the enamel on your teeth.\n\nBeware of using Pearl Drops, Eucryl or other so called tooth polishes. They are too abrasive to be used regularly and make the staining worse eventually by roughening the enamel so the stain sticks all the more.\n\nIf it's any recommendation, I use this myself too!\n\np.s. Crest Whitening Strips are NOT available in the UK, the Americans have not been reading the questions again...........

Galvinisation with zinc. \n\nChroming\n\nboth work off the basis of reduction and their poteintal to be oxidised\n\nlook in an chemistry A-Level text book. Or if your american look at a college text book, for exact details

Any acid.  Vinegar is the best probably.

Most efficient? If you don't have a lab, then I would assume just doing your best at grinding off the top layer, and trying to melt the shreddings down into a >70% gold alloy. Since gold's melting point is OVER 1000 degrees Celsius, I suppose your best bet is to heat the grindings as much as possible, and then pounding them together into a single mass (like a black-smith...or 'gold-smith'). But you have to realize HOW LITTLE gold is actually on there. The layer is so thin...sometimes merely 2-3 micrometers. You're gonna get a lot of impurities, such as nickel and copper. Gold-plating is usually done on copper or silver; and in the case of copper, a thin layer of nickel is placed below the gold. And since the melting point of nickel isn't that far from that of gold, and copper's is almost EXACTLY that of gold's, you're gonna get a random mixture of crap. I imagine the process is more trouble than it's worth. I'd just go buy gold from alfa aesar or somewhere like that for cheap-as-free.

Try it.\nThe easiest source of citric acid is lemon juice.\n\nThe usual solvent for nail varnish is acetone. This is the chemical with that lovely smell in nail polish remover. The point of using varnish is that watery things do not dissolve it.

Take a soft, slightly damp cloth and literally polish the bar.  Hope that helps!

Cut tips off then soak in acetone it will take a while but it's cheaper than going to a salon

Here are two techniques:\n\nFirst is to lay scotch tape over the nail leaving the tip you want to paint white.  Paint the nail tip, let the paint dry, then remove the tape.\n\nSecond is the type I use, but it takes a little more practice.  Place the tip of the finger you want to paint on a flat surface like a table.  Get a fair amount of nailpolish on the brush.  Roll the finger so the far edge is faceing up, put the polish brush against your nail tip, and then roll the finger away from you slowly and smoothly.  This will paint a smooth, straight line of white.

Use an eraser.It will take off tarnish and makes copper shine like new.For silver coins...Boil water in an aluminum pan ,add coins then add baking soda and remove from heat.Baking soda will cause a reaction and instantly clean the silver.Just rub w/ clean cloth afterwards.

you could try  a fine steelwool, i would start with 0000 and work your way up to larger grades as needed but this will remove the blueing. if the pitting is only minor i would use a soft scotchbrite pad and a light oil such as 3 in 1 oil . rub lightly, this should remove the rust with minamal damage to the finish,remove the oil with a soapy rag ,rinse with a clean rag ,let dry then touch up with a blueing pen or luiquid blue and a cotton swuab.

The method actually depends on what kind of jewellery your are trying to clean.\n\nAs an alternate to doing it at home, if the piece is basically metallic with gemstones, you can often just bring it to a reputable jeweller at your local shopping mall. They will gladly clean the item while you shop the mall, then pick it up when you return. They will usually place it in an ultrasonic bath, then steam-clean it and dry it when you return. They do this free because they hope you will consider them the next time you need to make a jewellery purchase. Be sure to ask if it is free though, because some do charge for this service.\n\nIf your piece of jewellery is more delicate, you have to take more care. Necklaces with silk or fibrous cords can not be subjected to harsh cleaners, and should be treated with care. Also, some gemstones are coated with a very fine oil that enhances the gem's beauty. Many cleaning techniques will remove this oil, and unless you replace the oil, your gemstone will appear dull and possibly worse than it did when you started. If you have expensive jewellery, you are advised to do some basic research on the cleaning methods for your exact gemstone (semi-precious or not).\n\nIf you have taken the above into consideration and still wish to clean your own jewellery, the easiest and safest method is to use simple dish-soap and a toothbrush. NEVER use toothpaste! Toothpaste has an abrasive compound in it that can actually scratch metals, and leave swirl-marks from your cleaning attempt! After brushing your jewellery piece with soap and toothbrush, rinse it well, then dry it completely. If the jewellery piece has a fibrous or silk rope holding it together, resist the temptation to immediately wear the jewellery. The cord will have absorbed water, and the weight of the piece (or the slight tension you may unknowingly place on it) will stretch the cord. When it dries it will then have spaces between your gemstones or pearls, which is not an attractive look, and there is no way to repair the damage.\n\nSimple silver and gold jewellery can also be cleaned with special cleaning cloths, available at most jewellery stores. They can also sell you special cleaning products for hard-to-remove stains, or hard-to-clean specialty pieces.\n\nGood luck with cleaning your jewellery!\n\nI have posted an expanded answer in the sources page below.

Try fingernail polish remover.  It really depends on the resin.  Some may take solvents such as hexane or acetone.
