Hello and thank you for your help! We had a situation in which after eating chicken, we accidentally put the meat utensils in the dairy sink on top of a plate with a spoon that was used for cheese just a few hours before. The dairy plate and spoon were cold since they had been in the sink for a while and the meat utensils were also not hot since we were just eating with them. After we realized what happened, we put lots of soap on everything and washed everything separately. Are all the dishes still kosher? Thank you!

ב"ה Shalom Yes, the dishes are kosher. One of the conditions of dishes becoming not kosher is when the meat and the dairy dishes are hot. As you specified, this was clearly not the case. Scrubbing them clean with soap was the right thing to do in this case. All the best
