You're not going to like this answer.. Too many "it depends".

1. For those with wheat still in the field, the toxin will continue to grow at grain moistures above ~ 18%. As well, any re-wetting to moistures above this will get the toxin level to grow again. (Note: here in the Great Lakes Basin, we can have 13-14% grain at 4pm in the afternoon, and the following morning will be back over 20% - our humidity gyrates like that daily..) In our part of the world, one of the VOM risk mitigation strategies is to fire up the dryer, and go get it off. Note: if you have clean wheat when everyone else doesn't, you are in the drivers seat if you have a way to hold it off the market.
2. Depending on when the initial infection happened - early or late in the flowering period - will determine whether or not 'cleaning' will reduce the VOM level. An early infection will have the gray, chalky kernels that are really light. They come out easy. A later infection will have healthy kernels that you can see a little fuzz between the cheeks of the kernel. This might test high for VOM, but will be virtually impossible to clean out because there is no density difference between infected and not infected kernels.
3. Worse case scenario - an early infection, then stays wet and rainy. You have the chalky kernels, but the infection continued to spread up and down the rachis (spine of the head) and infect healthy kernels late. Essentially you have both a late and early infection. Cleaning the visibly infected kernels out will bring your VOM down, but perhaps not enough to make it suitable for domestic consumption.

Your best bet: find someone with a good seed plant that has a gravity table. Do some toxin testing before you start, then run some ton batches out the other end using different settings of aggressiveness. Either sample them for VOM, or take them to the end user for their opinion. If the hardest cleanout of 10% or so still isn't cutting it, find a feed market.

Last, be very careful with the cleanout. Don't feed it to the kids 4-H calves or hog project. This stuff is TOXIC. It can be fed, in minute amounts to species that have a tolerance for it...
