Let the mud dry, brush off as much as you can, then pretreat what is left with detergent. The American Cleaning Institute’s stain guide says that when mud is dry, you should brush off as much as possible before any washing.

What the guide says

For mud, ACI says to brush off as much as possible when it is dry, and then to pretreat with a paste of powder detergent and water, liquid laundry detergent or a liquid detergent booster, before laundering.
ACI’s general advice is to treat stains as early as possible, and not to put the item in a dryer until the stain has been removed.
Its laundry basics page says to follow the care instructions on the item.

What to do

Let the mud dry completely in a place where it does not matter.
Brush it off with a stiff brush, working away from seams and zips.
Pretreat what is left with a little liquid detergent, and work it in gently.
Rinse by sponging with clean water, and repeat if you need to.
Dry the bag open, in moving air and away from direct heat.

What to check first

Does the bag have a care label, or a maker’s care page?
Are there leather parts, foam padding or a coating?
Does the colour stay on a damp cloth when you test a hidden spot?

Where this answer stops

ACI’s guide is for washable clothing. A bag’s coating, foam or glue may react differently, so follow the maker’s advice if you have it. Test first and go gently.

Empty and open every pocket before you start, and shake out loose grit outdoors. Mud trapped in a zip track or a seam keeps wearing at the fabric long after the stain is gone.

Check the bag’s label or the maker’s website for how to wash it. Some outdoor bags have coatings or foam backs, and the maker is the best source for what they can take.

Do not scrub wet mud into the weave. Waiting a little, until the mud is dry, lets you brush most of it away, and what is left is a smaller job.
