That's part of the fun of learning, making mistakes. Doubtful you'll do that again. Don't worry about "doing something stupid". You'll do lots of stupid things, lol. Ok I've done lots of stupid stuff.

I know many keep the water running to rinse; I prefer to fill the basin and swish the blade spine side down to rinse.

My routine...fill basin with hot water, soak brush, scuttle and lather bowl as I shower. Remove items from basin and leave the sink with the warm water till end of shave.

The standing water works fine for me to rinse soap from the blade edge. I tend to get water on the pivot if I rinse over running water, so this stops me from my clumsiness there too. Plus I get to feel pompus that I saved a gallon of running water from going down the drain, lol
