Hi,
Earlier this year I mastered a Depeche Mode live recording I made, and it contained lots of static clicks and even some clipping. The static noise sounded close to the sound of claps, and could (in my case) most often, easily be spotted as high peaks.
Using Sony's Soundforge, and an externally downloaded (trial) version of a 'vinyl restoration filter', I managed to get rid of most of them, and I removed the others by hand (by zooming in on the peak, and either flatlining it, or interpolating it, depending on what sounded best). The first part was easy, of course, and got rid of some 75% of the static noise, the latter was tedious, but when doing a few songs a night, within a few days the whole recording is properly mastered.
I realise claps are not the same as static noise and clipping, but you may give such a filter a go and see if you can configure it properly, such that it recognises the (hopefully 'sharp') noise of the claps as being static noise.
If not, I'd probably try manually zooming in on a few of the claps (one at a time, of course) and trying the "audio fix" -> "interpolate" option, and then listening back to the manually changed section. If it sounds good, you can try to set-up an automatic filter, or undergo the (tedious) process of manually fixing up everything.

Cheers!
