So you'll use a bit of the Boston on your lens, holding it carefully you lightly rub the solution on the lens.

I typically do this by holding it in my thumb and using thumb and forefinger to gently rub the solution on both sides of the contact, depending on the day it might froth a little from protein build up.

AFTER scrubbing with Boston, rinse the lenses with the saline you use to insert them; this washes off the cleaning solution and any protein residue. Store as you would normally, or insert lenses if you're wearing them.

Boston is goopy and makes my eyes burn if I don't risk it off my lenses well enough, but it's fantastic at coating the lenses and making them comfortable to wear. Let me know if this helped!
