Free auto & mechanics tip: Dish soap, bleach, and other bad ideas (step 7 of 12 from "Wipers, Washer Fluid & Cabin Filter").
Dish soap foams in the pump, strips wax into the glass, and can freeze. Bleach and ammonia wreck paint and trim if they dribble. Plain water in winter freezes in the nozzles — you will be drilling ice at a red light. Fill with labeled washer fluid only.
If the fluid you have is neon and smells like a bar floor, it is still better than soap. Top up to the full mark, not overflowing onto the belt. A funnel keeps it off the alternator. Spills: wipe with water. Washer fluid on hot exhaust is a smell, not a fire, but do not make a habit of bathing the engine bay.
Pro tip: If washers spray weakly or not at all after a fill, the nozzles may be clogged with wax. A pin in the jet, gently, from the front — not a screw through the hood insulation.
