Rather give them plenty of time to dissipate
Yes.
and use best rate of climb speed to get above them.
Ahhh, not so fast... Yes, above wake turbulence is the most desirable place to be, but trying to get there can end badly. Most of us do not fly aircraft with that kind of climb capability. I will not fly through a zone I think could contain wake turbulence, so I would not be climbing through it! I will be either waiting the full wait, or determining a path which will take me around the risk area, not through it!
The tactics of wake turbulence avoidance are well documented, and worthy of review.
