As per the title ........ I bought a 30'odd year old leather flying helmet and goggles , but it has spent most of that time at the back of a cupboard and has a strong 'musty' smell ....... the smell seems to be mainly in the fabric liner and thats not removable so I cant whip it out and wash it .......

So what I need is something moist to dab on my helmet ...... that'll take out the smell but not damage the fabric liner or the leather outer ........ any ideas ?
