Make sure to soak up the aligner for a couple of minutes before brushing or rinsing it.
Never rinse your Invisalign with hot water, as this could melt and permanently damage the aligners. Some dentists recommend not using toothpaste, as it often contains abrasive ingredients that leave scratches on your trays. Over time, the aligners become more visible. If this is a concern, brush with water only, or using a mild dish detergent. [1] X Research source
Rinse your hands and the sonic appliance as well.
Note that hydrogen peroxide will not remove plaque build-up.
The vinegar smell will disappear soon, don’t worry.
