The cleaning method of the surface oxide layer of titanium and titanium alloy cold pressed products is characterized in that the cleaning solution is prepared by adopting nitric acid with chemical purity of 15%~30% volume fraction, hydrofluoric acid with chemical purity of 8%~16% volume fraction, and the rest is water; Cleaning steps: 1) Place the cold pressed product to be cleaned face up on a plastic bucket with a water filter plate; 2) Pick up an appropriate amount of absorbent cotton with bamboo tweezers and dip the prepared cleaning solution; Evenly and brush the inside of the composite cold press pan until the internal surface defect of the pan disappears; 3) Rinse the inside of the composite cold press pan with clean water, wipe the surface water, and use a hair dryer to let it dry fully.
