Bicycle helmets can get pretty full of stank. In my case, the ripeness seems to come from the little liner pads that are velcroed in there and soak up sweat and grease. Removing them for cleaning is pretty easy, but I haven’t had such great success with hand washing in the sink. Plus, that requires effort.
On the other hand, simply throwing them into the washing machine just about guarantees they’re gonna get lost. And being a dude means I don’t own a linen bag for my “delicates”. What to do?
The solution is simple — throw the pads into a jersey that has a zipper pocket, zip the pocket closed, and then throw the jersey in with the rest of the wash. Done.
