How oxalic acid remove rust

Oxalic acid is a potent but toxic cleaner that removes rust and stains caused by iron, water and tannic acid. It’s available in dry crystal form, to be dissolved in warm water for use

Oxalic acid how to use

Oxalic acid is the perfect chemical for removing stains from timber. It’s made from rhubarb leaves & comes in a crystal form.

Oxalic acid is used for:

• Removal of tannin stains in oak or timber
• Removal of iron stains
• Boat cleaning
• Bleaching wood
• Removing brick stains
• Furniture restoration
• Bee keeping

You will need:

• A container
• A brush
• Scrubbing brush
• Safety gloves
• A mask

Avoid contact with the skin & eyes.

The process is extremely simple. We have split it out into 4 steps. It can be completed very simply in a matter of minutes:

1. Mix one part oxalic acid with 6 parts warm water
2. Apply a liberal amount of the mixture to the timber using a brush or sprayer
3. Use the scrubbing brush to scrub the stains
4. Allow to dry – the timber will dry without the stains

Oxalic acid how to use wood bleach

To remove stains:
Dissolve 12 to 16 ounces of oxalic acid crystals into one gallon (or 2-4 oz. in a quart) of hot water.
Use solution while hot, with a scrub brush.
Apply liberally allowing solution to remain on surface until desired lightness has been achieved.
If solution cools before job is finished, reheat solution (do not boil).
Triple rinse thouroughly with clean water
and allow to dry.

When completely dry, lightly sand the surface. Surface must be clean and completely dry (not just surface dry) before refinishing.
Incomplete drying and retained subsurface moisture can cause finish adhesion failure.

After Stripping and to Lighten:
To restore wood tones (especially for oak)
Restore clarity and the natural tones of the wood without effecting the patina. Use 3 to 5 oz. per gallon of hot water then apply by spray, brush or wipe on. Rinse thoroughly with clean water.

Oxalic acid crystals how to use

Oxalic Acid Crystals remove stains such as ink from wood, rust stains from a variety of materials such as concrete and also mildly bleaches wood. Oxalic Acid can also help removal of rust from metal surfaces.

Oxalic Acid is also used for cleaning fibreglass boat decks and hulls. Oxalic Acid is found naturally in many plants.

Oxalic Acid is supplied in the form of fine white crystals, which should be diluted by adding approximately 75-100g of crystals to 1 litre of warm water. This solution should be applied to a stain, left to dry and then rinsed with clean water.

Image is for illustration only and product supplied may vary.

A ready made solution is also available – Liberon Wood Bleacher

Oxalic Acid Crystals are slightly toxic and therefore protective equipment, such as gloves and safety glasses should be used.

A safety data sheet will be sent with every order.

How to use oxalic in clothes

Wet the stain and sprinkle OXALIC ACID on it.  Rub with a wet cloth, sponge or brush until stain has vanished.  Rinse thoroughly and wipe dry.  For more stubborn stains, make a paste of OXALIC ACID and water, apply to the stain and allow to stand a minute or two before rubbing.  Rinse and wipe dry.  To whiten iron stained clothes, presoak using 4 tablespoon of OXALIC ACID in 2 gallons of water. OXALIC ACID can also be sprinkled in the toilet bowl and other porcelain surfaces to clean embedded rust and hard water stains.

How to use oxalic acid laundry

• add the affected laundry plus 100-200g of product to the washing machine and run on a hot wash or hot pre-soak program.
• If possible allow some soaking time as this will enhance stain removal
• Do Not add any other chemical or detergent.
• Run the machine through the full wash cycle to throughly rinse the laundry
• To complete the process run the treated linen through a full wash cycle in the usual way with added detergent
• As iron staining may vary it may be necessary to repeat treatment process or increase the concentration of Oxalic Acid.

How to use oxalic acid on glass

Rust does not develop on glass, but rust stains can drip onto glass windows from rusting metal roof gutters or onto glass mirrors from rusting metal light fixtures. You can remove the rust marks with simple household cleaners and products. Never use metal scrapers or coarse steel wool to clean glass, since those items can easily scratch the glass.

How to clean quartz with oxalic acid

Removing Minor Tarnish and Stains

Use an old toothbrush. If you have just a few quartz crystals or crystals that are only slightly tarnished by clay, you can use an old toothbrush to clean them off. Simply wet the toothbrush with water and scrub the quartz crystals in your hand.^[1]

• You can even use scouring powder and a steel brush for tougher stains, as quartz is a very durable material.

Dry the quartz crystals in the sunlight. If your quartz crystals are covered by a large amount of clay, you can place them outside in indirect sunlight for several hours to let the clay dry and crack. Once the clay is sufficiently dry, you should be able to brush off the remnants.^[2]

• You may need to repeat this process several times.
• Be sure not to place the crystals in direct sunlight because this could cause them to heat up too quickly and become damaged or cracked.
• This method will only work to remove dried clay from your quartz crystals. If the quartz is covered in iron deposits, you’ll need to use an oxalic acid method.

Remove iron stains with a high pressure water tool. Most iron stains can be removed with a high pressure water gun. Simply shoot the water spray at the quartz crystal and watch the stains disappear. This will work for most iron stains on your quartz, leaving only some slight staining in the cracks of the crystal.^[3]

• You can also try removing many of the iron stains with a high pressure air tool.

Removing Deposits and Tough Stains

Soak overnight in oxalic acid to remove iron deposits. If your quartz crystals have only a small outer layer of iron, you should be able to thoroughly clean them by soaking them in a weak solution of oxalic acid overnight. Put the quartz crystals in a plastic bucket with the oxalic acid and cover the bucket overnight.^[4]

• You can rinse the crystals with a garden hose or in the sink the next day. Be sure to stopper the sink so that you don’t lose any of the crystals.
• Oxalic acid can be purchased from most drug stores in powder form.

Remove stains by soaking in a store-bought solution. You can purchase a cleaning solution called Iron Out at most home improvement or household stores (like WalMart). Simply soak the quartz crystals in the cleaning solution and watch the stains disappear. You may have to let the crystals soak for days or even weeks for them to become completely untarnished.^[5]

• Be sure to rinse the quartz crystals with water when you finish.
• If you want to make your own Iron Out cleaning solution, you can combine 33 grams of sodium dithionite, 28 grams or sodium bicarbonate, 59 grams of sodium citrate, and 800 milliliters of water. Simply swirl the mixture around until all of the chemicals are dissolved in the water.

Remove algae deposits by soaking the crystals in bleach. If your quartz crystals are covered in algae deposits or other minerals, you can try cleaning them with household bleach. Soak the crystals in a bowl filled with water-diluted bleach and let them sit for several days.

• Be sure to rinse the quartz crystals well after taking them out of the bleach solution.
• Let the crystals dry thoroughly (for at least one day) before you begin any other kind of chemical cleaning.

Taking the Proper Precautions

Perform the cleaning in a well-ventilated area. Whenever you are cleaning quartz crystals with oxalic acid, you need to do it in a highly ventilated area. These fumes can be very harmful to you if you inhale them. Acidic fumes can be poisonous to animals and humans

Wear gloves when handling any type of acid. In addition to being harmful if inhaled, acid can burn you if it comes into direct contact with your skin. Be sure to wear rubber gloves when handling oxalic acid and while cleaning quartz crystals.

• Make sure to wear rubber gloves and not fabric gloves. The acidic residue could remain on the fabric gloves or seep through to your skin.

Dispose of the acid waste properly. Since oxalic acid waste is considered a hazardous material, you need to neutralize it first before you can dispose of it. At the end of the cleaning process, the oxalic acid will be in a liquid form. You need to add garden lime (CaO) to the liquid until there is no longer any visible reaction.^[7]

• You can do this outside on the ground and wash away the remnants with a hose. Or you can do it by using a funnel to pour the spent oxalic acid into a gallon jug and add the lime in there. Then simply throw away the jug and its contents in a trashcan or dumpster.
