cleaning marble and granite

I should have taken pics of the sink as well. It's a top mount. I should probably duct tape off the sink edges just to be safe in case I hit with the diamonds.
 It's a tight area between the taps and faucet to the blacksplash and sink.

Thanks Jos. I'll stop by in the next week and mention about them removing the taps or I have to charge extra, I think it's usually 31/2" or 4" from the sink to the back splash. I usually try to make it 4"

On another note. Installed a white Persian Granite today. Disaster from the "get go" Chipped both pieces of granite on the install. I ended up faking it in by using the technique that you suggested JOS and they could not even tell the dif.  My buddy (the owner) could not believe it.  Where was the cam then. LOL

Crap!!! Forgot to send in some pics!! So much for that.
The guy in the shop told me today I'll never be able to get those scratches out of that counter. He says that the scratches will be stained and the marks will still be there. I told him I'll get them out.
 I'll start with the 50 and start feathering the other grits. I guess I should start where the scratches are and then work my way down the counter but I should not have to go all the way down tho just so long as not to make any dips where I start grinding. Buddy's kinda got me thinking now if I should tackle this

 Did you make that short vid yet Joh?

Have a good one. Mark
