Lumo Pickling Gel
High adhesion stainless steel pickling gel. Used to remove the black oxide marks and heat tint left during welding of stainless steel.
Health & Safety
LUMO PICKLING GEL being a blend of aggressive acids must be treated with caution. In the case of accidental contact, apply Calcium Gluconate gel. Avoid contact with eyes or breathing any vapour. Replace the lid on the container tightly and store upright in a cool dry area away from direct sunlight. Do not store or use below 5°C. Caution: this product contains Hydrofluoric Acid and Nitric acid and is corrosive and poisonous. Do not use near open flames or cutting torches, since a hazardous flammable gas can be generated. Keep out of reach of children. If using in poorly ventilated areas, use a respirator equipped with an acid fume type filler. If you have to neutralise the residue, this can be done using an alkaline solution of sodium hydroxide.
Full protective clothing such as gloves, eye or face shield and rubber boots must be worn.

Benefits
Does not contain Hydrochloric Acid or any of the halogen group of chemicals. Quick acting. One step treatment. Completely water rinsable. Can be used on vertical and overhead surfaces.
Application (How To Use)
Clean the weld area carefully using a stainless-steel brush. Shake the container for 10 -20 seconds prior to opening the container to ensure a smooth consistency, especially if the product has not been used for a long time. After welding ensure the area to be pickled has sufficient time to cool below 40°C. Apply to the area to be pickled with the brush provided. DO NOT PICKLE IN DIRECT SUNLIGHT. Application times may vary depending on ambient temperatures. The grade of stainless, surface finish or the method of welding. On a hot rolled surface the pickling time may increase by 50%. MIG welds may require longer pickling times than those obtained using covered electrodes. Allow the pickling gel or solution sufficient time to react with the surface. With high ambient temperatures or when longer pickling times are required, it may be necessary to repeat the process. Should the product dry on the surface, wash down, dry and repeat the process. Do not over pickle – the best results are obtained by continuous visual inspection of the surface. To clean, rinse the surface with clean potable water. The best results are obtained by the use of high pressure water jet or similar. Ensure the pickle residues are not left on the surface.
