I have had a Victorinox BigBen for the last 5 years and I just love it!

It is of course black and does not show any smudge or dirt, even though I almost always end up shoving it underneath the seat in front of me on my flights.

How would you typically clean the ballistic nylon material on the outside, other than with a brush (e.g., clean, unused shoe brush)? Are there special cleaning agents like those for certain shoes?

I never expected to have a bag last me this long, and usually my solution to previous dirty bags was to get a new one! Although usually the bag being replaced would look pretty beat up already.

Thanks for any info.
