Question ICV Cleaning: TB or MAF Cleaner?

Replaced my intake boots, a vacuum tube, & cleaned my throttle body, my MAF, amongst an array of other things the week before last. But I didn't clean my ICV while I was in there... looking back I wish I had done this, but since ANOTHER tube has evidently ruptured, I'm planning on cleaning it while I'm in there finding out just what additional piece of rubber has decided to inconveniently go to sh**. Have been having a rough idle issue anyway. But I'm wondering which product to use. I have CRC MAF cleaner and CRC TB cleaner, but I've heard both being used to clean the ICV. Apparently the ICV is made of the same material(s) as the TB, and that's what I've heard used the most, but I would just like to go ahead and clarify before I go spraying the wrong chemical in there.

Dreaming of the ///M.

My understanding is that the MAF cleaner is a gentle electrical sensor cleaner, whereas TB cleaner is a little more harsh. I used TB cleaner with no problems, and that'd probably be a little more effective than an electrical sensor cleaner like a MAF cleaner.

I used the TB cleaner on the ICV months ago and it works fine.

Same material with a flap. That says it all.
