Oxalic Acid 99.5%
OXALIC ACID
99.5% Pure White Powder
Molecular formula: C2H2O4 * 2H2O
Oxalic acid is a chemical compound primarily used in commercial and household cleaning. Also known as ethanoic acid, oxalic acid crystals dissolve easily in water and is a highly reliable stain removal. It also functions as a rust remover and bleaching agent on various surfaces, including wood and metal. Mixing oxalic powder in water creates an acid solution useful in moderate doses but quite dangerous in high concentrations.
This makes it essential to research and verify what concentrations and mixing rates of oxalic acid is necessary for your cleaning project.
What Is Oxalic Acid Used For?
Oxalic acid has a wide variety of uses, some of which include:
1) Bleaching:
Oxalic acid powder may be used in bleaching wood and stone surfaces. Its bleaching properties can revive old, stained, and greying wooden floors. The acid may also be applied to lighten spots darkened by stains and in refinishing projects to make your wooden floor as beautiful as new.
2) Removing Stains:
Sometimes, household surfaces lose their beauty to food, ink and other corrosive stains. oXALIC acid is stronger and feeds on stains that regular cleaning agents find difficult to remove. Common but stubborn stains on your vinyl, brick, stone and wood surfaces can be removed by the ethanedioic acid without risk to the underlying surface.
3) Rust Removal:
Oxalic acid is also useful in saying goodbye to the rusts that accumulate around your kitchen tops and plumbing pipes. Many cleaning agents made for sinks, metal stains, tubs and countertops contain oxalic acid in varying degrees.
4) Oxalic acid can also be used in the following ways:
treating and removing calcium from wastewater, developing photographic films, polishing marble, furniture restoration and electrolytic oxidation of aluminium. It is also used in manufacturing dyes and sanitary cleaners.
How To Use Oxalic Acid:
The acid powder should be dissolved in warm water at a 5% concentration (i.e. a 1litre solution should have 950ml of water and 50g of acid powder). Shake the mixture well to ensure all oxalic acid crystals have dissolved. A 1litre solution should have 950ml of water and 50g of acid powder.
When removing stains from wood surfaces, ensure that the wood is sanded down and without paint for effective bleaching. You should apply the solution with a paintbrush or sponge for even distribution. Leave the solution in for one hour, then wash off with water and apply dry vanish.
If the 5% solution proves ineffective, you may increase it to 8 or 10%. You should avoid using this solution on sealed floorings as it will eat through the finishing. Although useful in cleaning fabrics, this process takes time, and it’s advisable to dry clean instead.
