1. Using vinegar

Vinegar has effective disinfecting properties making it an excellent cleaner for various surfaces in your camper. Its smell may be sharp but it will fade in no time and work well on your ceiling, wall, floor, and so on.

To use this, just dilute white vinegar and pour it into a spray bottle. Distribute it evenly on the areas of mildew growth and allow it to sit for a few minutes and work its magic on the fungi.

If you don’t have a spray bottle, you can also wet a clean and dry piece of cloth and use it to wipe over the affected areas. It will work just as fine.


2. Using distilled ethanol

When dealing with severe cases of mildew contamination, ethanol is a better option. If you feel like the damage was out of control and you need a stronger cleaner, diluted ethanol will come to your rescue.
