I've searched the forums and may have missed it but looking for the best way for gum removal. I'm thinking just powering it off?

What you want to do is perform a regular concrete cleaning like usual with the surface cleaning tool. Then go back with the wand, I like to use a 15 degree tip with about 3000psi, start working up all the gum one piece or group of pieces at a time. Use the psi's and fan pattern like a putty knife and peel the gum up. I highly recommend using hot water, it will be much more efficient and effective compared to cold water.

Just be extremely careful not to damage the concrete with too much pressure. All cement surfaces differ from one another. The materials used in the cement pour, the cement's age, environmental conditions, and deterioration rate will all vary from one slab to another.

It is vital to know when too much pressure is too much, and when to back it down a little. Maybe start with less pressure, like 2000psi or so, until you get more experienced.
