Moisture is the main enemy
Corn-filled bags absorb water, gain weight, and can mold or sprout if stored damp. Resin-filled bags do not absorb, but the fabric still holds moisture and a wet face plays completely differently from a dry one.
If bags get caught in rain or heavy dew, spread them out in a single layer indoors until fully dry before putting them away. Direct heat from a dryer or a heater will shrink and stiffen the fabric.
| Condition | Corn fill | Resin fill | Notes |
|---|---|---|---|
| Wet from rain | Air dry fully, check for odor | Air dry fully | No dryer or direct heat |
| Surface dirt | Dry brush | Dry brush | Avoid scrubbing wet fabric |
| Deep clean | Not recommended | Cold hand wash if maker allows | Check the model's guidance |
| Long-term storage | Breathable container, cool and dry | Breathable container, cool and dry | Avoid sealed plastic |
| Worn slow side | Replace the set | Replace the set | Replace all 8 together |
Cleaning by fill type
For dirt and grass, let the bag dry and then brush it with a stiff bristle brush. Working dirt out dry avoids driving it into the weave, which is what happens when you scrub a wet bag.
Machine washing is not appropriate for corn fill. Some resin-filled bags tolerate a cold hand wash with mild soap and air drying, but check the manufacturer's guidance for the specific model, since the fabric treatment on a dual-sided bag can be affected.
Storage
Store bags loose in a breathable bag or box rather than sealed in plastic, which traps moisture. Keep them out of a hot car trunk over a summer, since sustained heat is hard on both fabric coating and resin fill.
Keep a set approved for competition separate from a backyard set. Practicing on rough concrete and gravel wears fabric faster than anything else, and mixing sets means the wear lands on the bags you care about.
When to replace
Retire bags when the slow side stops holding, when seams open, or when the bag no longer sits square. Loss of the speed difference between faces happens gradually, which is why regular players judge by how the bags behave rather than by how they look.
Replacing all 8 bags at once is the cleaner approach. A set with two new bags and six worn ones gives inconsistent feedback while you are trying to calibrate a throw.

A few common questions
Can I put cornhole bags in the washing machine?
Corn-filled bags should not go in a machine. Some resin-filled bags tolerate cold hand washing, but follow the manufacturer's guidance for that model rather than a general rule.
How long does a set of bags last?
It depends on how often you play and what surface the bags land on. Judge by behavior, replacing the set when the slow side stops gripping or seams start to open.
