How to Clean Your Tent Top.
Everyone will have there own ideas of how to clean their tent. We have found that pressure washers, etc.. are not as deep cleaning and perhaps harmful. Particularly to older tents.
Following is how we would clean a tent: For initial cleaning, spread tent out on grass, get wide nylon bristle brooms, take your shoes off and spread non concentrated laundry detergent out, water and get to work. That will take most of the dirt off.
You can experiment with different spot cleaners for bad areas. Always test small area first. We like "Mean Green Super Strength Cleaner" available at Dollar General Stores. WD 40 will take off tar and other odd marks. For other tough areas you can use 3 parts water 1 part Clorox to scrub with. Do one panel at a time and then wash off immediately, otherwise it will take gloss off top of tent. You can use this same mix of Clorox and water on underside, where seatbelts show, and actually let it dry without washing off. This will help fight mildew in the future.
