Applications
DERUSTING SOLUTION is also suitable for preparing steel and aluminium surfaces for painting in immersion (Vat) or hand-wipe applications. Use of DERUSTING SOLUTION for cleaning, rust removal or pre-paint preparation must be followed with a fresh water rinse and drying. If used prior to painting, parts should be painted after the drying step.

Dosage and directions
Equipment :
Customer Owned Machines Immersion (other common terms - Vats, Dip Tanks, Hot Tanks).
Note: Tanks (Vats) should be made of stainless steel (304, 316, or 347), ceramics or other acid proof materials. Heating elements should be made of stainless steel, impervious carbon or graphite. Do not use Monel equipment, lead or rubber lining in tanks.
Soils :
Light to moderate grease and oil. Light to heavy rust, heat scale, flux, and other oxides.
Operating Instructions:
Immersion: Use 5% to 25% volume with water at room temperature to 160ºF. Follow the cleaning step with fresh water rinsing and drying. The higher the concentration and heat, the faster the rust removal. Immersion time depends on the degree of soil and amount of rust to be removed. Hand Wipe: Use 10% to 50%/volume added to water at room temperature to 120ºF. Apply with clean rags, wipes or brushes. Allow the Rust Remover to soak on part surfaces for several minutes before wiping or brushing for improved results. Follow with fresh water rinsing then dry the parts.
*Note: Use acid resistant gloves and safety glasses when handling this product. Refer to the
product MSDS for complete safety instructions.
Characteristics and notes
Titration Procedure (insert “Information”)
- Using a pipette, take a 5 ml sample of Rust Remover from the cleaning bath
- Put the 5 ml sample into the mixing flask
- Add 10 ml of water then stir well to mix
- Add 5 drops of phenolphthalein indicator
- Counting the drops added, add 10N Sodium Hydroxide one drop at a time until the solution turns from clear to purple. Swirl between drops. The number of drops needed is the concentration of the Rust Remover.
Precautions :
Not intended for spray use.
Do not use or mix with chlorine containing cleaners or solutions as chlorine gas can be released.
Will gradually attack steel tanks, heating elements and piping
This product is highly acidic. The product concentrate causes burns of the eyes and may cause burns of the skin.

Frequently asked questions
Jung saaf karne wala chemical kaise use karein? (How is the derusting chemical used?)
Dip parts in a 5–25% solution until rust and scale dissolve (minutes to an hour by severity), rinse in fresh water, dry, and paint promptly if the parts are for coating.
How is bath strength checked?
Titrate 5 ml of bath + 10 ml water with 10 N NaOH to the phenolphthalein end-point; the number of drops equals the bath concentration (see the data sheet).
Does it remove heat scale from welds?
Yes — heat scale, flux and oxides on steel and stainless; for weld-tint passivation see the Passivation range.
