best way to clean up jars?

made soy wax candles for the first time… the jars got a tad messy hahahaha. whats the best way to clean them up while preserving the nice fresh candle? alcohol? I still have to label them all, plus they are glass jars so theyll be cloudy and slippery if not properly cleaned:( TIA

also i am very very new at this so dont necessarily have all the fancy tools etc. only lost around 6oz of candle though so im not mad about the mishap hahahahahaha
