As others have said 35-40C may melt but certainly won’t clear i find bumping the temps to 50-55 and then give a quick shake or if you like a stir. The slightest agitation will remove larger crystals. If you do heat jars I like to drop the temperature after heating by sitting in a sink/bowl/tub of ice water. It’s not needed probably but I’ve made an effort to reduce the heated period.
