Removing Mildew from a Tent

Go to an RV store and buy the product they sell for cleaning camper canvases.

Lysol spray.

Try using white vinegar. It is great for mold/mildew removal and for preventing in the future. For heavy mildew, use full strength vinegar, or mix 1 part vinegar with 3 parts vinegar for light mildew. The smell of vinegar will be strong at first but will dry quickly. It will also help to deodorize the tent as well. As for using vinegar when camping, add a few drops of vinegar to your drinking canteen or thermos. It will keep the water fresh longer and be a better thirst quencher. You will not taste the vinegar.
