What is the best acid to clean stainless steel?

Nitric acid
Nitric acid is a “friendly” acid towards Stainless Steel and is the only mineral acid which should be used to clean stainless steel. Avoid contact of the acid with other metals, particularly the aluminium and copper bases on cookware. A 10% solution (1 part Nitric Acid added to 9 parts water) is usually used.

Is citric acid safe on metals?

Acids like citric acid dissolve metals but they dissolve rust (metal oxide) faster. Your chemistry book may tell you that an acid plus metal will yield hydrogen plus a salt of that metal, so the rust dissolves as a metal salt. Good luck.

Can citric acid damage surfaces?

Due to its acidic nature, citric acid can cause damage to certain surfaces, namely porous stone surfaces, like marble countertops, for example.

Can citric acid dissolve rust?

Citric acid is one of the easiest, safest, and least abrasive ways to remove surface rust from old steel tools and accessories. Citric acid allows you to easily and safely remove rust without damaging the steel finish. Citric acid is the main ingredient in many biodegradable cleaners and also used for baking.

Will oxalic acid damage stainless steel?

Bar Keepers Friend Cleanser contains oxalic acid, which breaks down and removes calcium deposits from hard water. Better still, it is non-abrasive, so it safe for stainless steel. Make sure to always dry your stainless steel with a soft cloth or towel in order to keep moisture from sitting on the surface.

Can you clean stainless steel with hydrochloric acid?

Strong acid solutions (e.g. hydrochloric acid or “spirits of salts”) are sometimes used to clean masonry and tiling of buildings but they should never be permitted to come into contact with metals, including stainless steel.

Is citric acid corrosive to steel?

Since citric acid is a weaker organic acid, it does not corrode iron rapidly. Over-the-counter solutions of citric acid are generally offered at low concentrations, so they are more safe. The citric acid chelates the iron oxide, leaving a clean piece of iron and a solid chelate that can be removed easily.

Will citric acid eat rust?
