What I recommend is:
Pick your favorite filter out of the 4 filters (B2, B3, A3 or A5).
Apply it on your photo.
You can reduce the intensity of the filter if it is too strong on some photos.
Increase contrast: for a sharp, clean look.
Increase exposure: if there is a lot of white in your photo. It will make your image sharper, brighter and cleaner.
Increase the sharpness: just a little bit (otherwise your photo will look too fake).
Use the whitening tool to make the background of your photo whiter (like the table, wall, floor).
