He stops in the shade of a large rock, takes the bottle out, opens it, and takes a mouthful. He slowly swallows it, making it last as long as he can. It feels so good in his dry and cracked throat that he doesn't even care about the nasty taste. He takes another mouthful, and makes it last too. Slowly, he drinks half the bottle. He figures that since he's drinking it, he might as well drink enough to make some difference and keep himself from passing out.
He's quit worrying about the denaturing of the wiper fluid. If it kills him, it kills him - if he didn't drink it, he'd die anyway. Besides, he's pretty sure that whatever substance they denature the fluid with is just designed to make you sick - their way of keeping winos from buying cheap wiper fluid for the ethanol content. He can handle throwing up, if it comes to that.
He walks. He walks in the hot, dry, windless desert. Sand, rocks, hills, dunes, the occasional scrawny cactus or dried bush. No sign of water. Sometimes he'll see a little movement to one side or the other, but whatever moved is usually gone before he can focus his eyes on it. Probably birds, lizards, or mice. Maybe snakes, though they usually move more at night. He's careful to stay away from the movements.
After a while, he begins to stagger. He's not sure if it's fatigue, heat stroke finally catching him, or maybe he was wrong and the denaturing of the wiper fluid was worse than he thought. He tries to steady himself, and keep going.
