Is there a way to get rid of white dots in image?

I want to remove the white dots from the image (attached) without affecting the rectangular signal. Is there any way to get rid of these white dots with script for data processing?

Thank you

medfilt2 would be appropriate.

A=imread('https://www.mathworks.com/matlabcentral/answers/uploaded_files/1129070/image.jpg');

imshow(medfilt2(A))
