Pretty common practice for most trades not to clean after themselves. Even the trades that do clean after themselves I have a hard time imagining cleaning the underside of the slab.
My experience is the same as yours. If you touch the underside of the slab you are likely to come away with dust - unless you personally cleaned it.
I wouldn't worry about it.

Well the best option is to only have one kickboard. Looking at yours I would just throw them away. For kickboards I use 1x and I use either pine or Azek. That is the area of the kitchen that has the most chance for water damage so don't use plywood or something like that. MDF would be your worst choice (isn't it the worst choice for ...
I'll answer with a practical suggestion, rather than precisely answering the "Can we" question with "you can!".
A complex appliance designed for indoors, full of electronic controls and sensors, and lots of hidden inaccessible crevices where moisture and insects can collect, is unlikely to last long outside, or to work at all in some ...

Trying to save 10$ (about a sheet) makes no sense to me because the Sheetrock gets damaged or has residue on it. I would rip& strip the tile and Sheetrock out and then if replacing with Sheetrock use green board or if tile use backer board to replace the Sheetrock.

I would be more worried about the igniter or if electronic how often it fails.
I have been asked several times if I could repair them and the high voltage circuits are usually potted and not repairable.
With potted electronics you are stuck purchasing expensive replacement parts.
And that may be the reason to sell (or a remodel).
I am not aware of any real ...
What about using the back of your fridge to preheat your make-up air? I had a mechanical consultant do that in an apartment building where the intake air was delivered to the gap behind the fridge..
Might be a nice (old-school) compromise..
I would simply cut the toe kick so that the butt joins occur where two cabinets join.
Then, I would find an appropriate piece of moulding to cover the joins.
The simplest solution is cheap plastic t-moulding (check in flooring) like this:
However, you can check around the flooring department for t-shaped transition mouldings that suit your needs (may be ...
Or should I just disassemble everything and bring them to Home depot

Yes, take the cartridge to Lowes and look for a match.
If you can not find a match then go to a plumbing supply house.
