Default Re: Why does hot water clean dishes better than cold?

The faster molecules bounce around, the more room there is for mixing, the less likely they are to clump together, the more force they have when they collide (and the more likely they are to knock one another loose), etc. And by adding energy to the system, you can make bonds break and increase the likelihood of reactions that might help the cleaning process.
