Wood – Is it okay to use rain to rinse off a deck after applying deck cleaner

I'm planning to refinish my deck soon. Here are some pictures of the current state of it.

I bought this Cabot wood cleaner. The instructions say to:

Apply cleaning solution liberally to problem surfaces using a brush or pump-type sprayer. Allow to set 15 to 20 minutes. Stubborn areas may require scrubbing with a stiff bristle brush. (If surface begins to dry quickly, lightly mist with water.) Rinse off using a garden hose with nozzle at maximum
pressure or use a high pressure power washer. Repeat procedure if necessary.

Currently the one spigot we have outdoors is shut off due to some plumbing work that is on pause, so using a hose is not an easy thing to do. It's supposed to rain tomorrow. If I apply the deck stripper before it starts raining, can I let the rain do the work of the Rinse off using a garden hose with nozzle at maximum pressure or use a high pressure power washer? Or would that cause damage to the deck since it will probably be raining all day?

No it’s not the same. Getting it “wet” isn’t the same as “rinsing it off”.

Boards are not perfectly flat. They cup, twist, have small crevices, etc. and will “hold” rain water. Rinsing the boards off will “wash” residue, particles, etc. away.
