What liquid or polish can we use to clean copper pipes externally and internally to remove oxidization?

What is the application for the copper pipes? That would make a difference as to the cleaning method.

As stated previously, the aplication will dictate what you should or shouldn't use. For cleaning the inside of the pipes Refrigeration Chiller Flush (available at any heating and air supply store) works wonders. Take heed though, its main ingredient is Hydrochloric Acid. If not used correctly it is hard on the pipes and burns the skin. (And everything else it touches)

Martha Stewart recommends lemon juice and salt.

There are also some more toxic concoctions available, like Tarn-X, which removes tarnish on contact.

If you clean corrosion from inside a pipe you must be mindful of new corrioson deepening the pits and having the pipe leak. In casr they put anticorrosion additives in the glycol they use.

In your application you must do the same with additives that suit your application.

Some applications are corrosion free.

The same goes for the outside, but you normally get a patina of copper oxide followed by green copper carnonate which is protective. Sadly, with SO2 in the air you can have dissolution of the copper carbonate, which is why copper roofing does not last as long as it did in the middle ages.

When cleaning pipes used for drinking water, chlorine is used in a closed loop over 24 hrs. After 24 hrs it is flushed and a ppm test is done on the water....this will assure the water delivery system is cleaned and at acceptable chlorine levels....keep in mind if you have chilled water fountains in the system you must allow for the holding tank volume when filling the system and flushing...the same goes for commodes and hot water tanks.

I have used Saf Acid, before, available from Drew Marine. It has a color indicator and does a great job removing scale, by circulating a solution, or immersing the object (like a heat exchanger for example) in the liquid and agitating with air or machanical means. It is quite user friendly, but the usual precautions (dont drink, eye and hand protection, no swimming) etc all apply.

Do a search "Saf Acid" and details will come up.

Assuming (the mother of all foul ups - assumption) that you are into a mickey mouse residential project and not some Middle East monster refinery, a cotton swab with a squit of fresh lemon juice and a sprinkling of table salt will clean off most scale from copper pipes. Rinse with water with a bit of bicarbonate of sode (baking soda) to neutralise the acid and then wash with clean water. Polish with a good metal polish on outside but leave inside as is for water feed. Ornamental use polish inside too. Depending on condition you may want to clean up the pipe outside with fine water paper 600 then 1200 grit. copper works real easy so have fun getting it to a pink mirror finish.

It all depends on how much pipe is involved what it is used for is it indoors outdoors?

Can you manualy reach it? Are you doing this to just look good or is there some other reason to polish the copper? The only reason to clean the inside must be to remove a build up of some corrosion or deposit of fur. Mild hydrochloric acid will desolve most water born salts. It will if left in also disolve the pipes as well. Braso and elbow grease will fetch up the outside.
