FIPROSTEEL 754 is a 300 series pickling gel for stainless steel that has the same technical characteristics as FIPROSTEEL 758 except that it is less viscous, therefore ready for use with a spray pump.
It allows the pickling of both the welded sections only and the entire surface without leaving unsightly traces. It does not create problems of use, even in sunny exposure, as long as you have the warning not to apply it on red-hot surfaces.
If you need to cool the surfaces first by spraying water before applying the gel.

Solubility in Water
FIPROSTEEL 754 must be used as it is with the sprayer. Wait the necessary time which, depending on the type of steel, thickness and type of welding, can vary from a few minutes to several hours. If necessary, before washing, go over the weld with a stainless steel brush. Wash with cold water, preferably with a pressure jet (pressure washer).
Not necessarily, but if you want to get a better result, after the first cold wash, follow with a hot wash.
Normal precautions are recommended when using an acid product. If you work inside a tank, it is essential to wear a gas mask and possibly forced ventilation.
