How many times do you need to ask??? I'd use colored caulking if you can find a color that is close or clear if you can't.....

Is that a corner mortar joint, if so it indicates yearly house shifting id guess. I would clean , grout, then caulk it since it will still shift. Clean well since its full of soap, lime residue and mold, a hand grout saw will get you new grout.

Silicone caulk - check the tube at the hardware store, as it will tell you what sufaces to use it on. Corners - wall-to-wall and to ceiling and floor - will always flex, so should be treated with something that is flexible and can expand/contract a little more than grout can. Be sure to clean the corner immaculately - scrub off all soap scum or deposits and then wipe down (and let dry, of course) with full-strength bleach so mold will not grow under the new caulk.

What a pig pen, you need to clean the place up b/4 attempting a fix.
