Some touch controls are incredibly good at filtering false inputs. Unfortunately you can't tell which.
the knobs on my manually operated range pull right off their posts and go soak in the sink with some soap and hot water once a week while i spray the range's control surface with whatever spray cleaner and wipe it off with every other flat surface in my kitchen.
after ten or fifteen minutes of soaking, anything left on the knobs fall off with a dry rag that goes in the cloth washer afterwards.
But I gotta say, the ability to just simply wipe the whole stove surface with a towel and be done has more than made up for the touch buttons sucking.
With physical knobs: Take knobs off and soak them, use a towel and wipe a circle around the nub that’s left, try not to leave a circular streak pattern, put knobs back. Or just wipe the knobs with the towel and get close enough on the surface.
Touch buttons: wipe the whole thing in big strokes, you’re done.
I clean the whole surface after every use now, because it’s just so damned easy.
What I really want is for the controls to not be on the cooking surface at all but that only seems to be available for stovetop + oven combinations which have their own annoying limitations.
Still bad design on many levels, but not quite what I would call a safety hazard for this reason alone.
Ideal would be to put the control surface further away from the cooking surface but that won't integrate into semi-standardized kitchen designs.
