This is an extreme case, but when performing radiological decontamination on people we were trained to avoid extreme temperatures when cleaning skin with water. Too cold closed skin pores which could trap particles, and too hot would enhance their adsorption into the bloodstream.
Your typical dirt and grime probably aren’t affected at the scale where this is a problem, but all the same.
