Yes.
You can use that brush to clean any product residue off any foam pad. The way I was using it was to hold the pad in my hand and draw the bristles against it over a box.
You can also use it with a rotary buffer as the buffer's running. There's more information about cleaning your buffing pads in this thread.
How to clean your foam pad on the fly Quote:

Kind of a little bit of both.
First, if you're using a specific type of foam for it's characteristics, in this case a cutting foam to cut with, then you want the foam in contact with the paint, so you need to clean the residue build-up from off the face of the pad for this reason.
Second, you always want to work clean. Adding fresh product to spent product dilutes or adulterates the fresh product, so for this reason you want to remove spent product. If you think about it, the residue on the surface of the pad is a mixture of both spent product and removed paint particles, you don't want to keep rubbing this against the paint, so you want to clean any build-up off the face of the pad and also wipe your surface clean before working that section again, if you're going to work it more than once.

The build-up is normal and you'll see it with any product you're applying and working against the paint. It's just a good practice to work clean, this applies if you're working by hand or by machine. It takes more time to stop the process, (by hand or machine), and clean you tools whatever they may be, but by working clean you're removing the potential for any problems because you've removed used-up product out of the process and you're enabling the pad of your choice to do it's job better because there's no spent product in the mix. Again, this would be true of working by hand or machine and applies to any product you're using to remove defects.
Not removing spent product can cause the process to become gummy and make wipe-off more difficult, this will slow you down and lower the quality of your end-results.
Can't stress enough the importance of always working clean.
Always great to hear from the Pro. 
Hope you got some serious overtime for the project
