It's not really a blitz, it's literally just:
Wash the dishes (or run dishwasher) every day for a week. By the end of the week she also has you wiping down the counters.
Wash dishes + sweep kitchen floor every day for a week. Doesn't need to be a full on sweep, just making sure there are no big objects on the floor. We have a robot hoover so in theory - easy peasy because I don't even need to do the sweeping.
Wash dishes + sweep kitchen + quick glance into bathrooms and remove anything that shouldn't be there every day for a week. And once you've done this once, the floor and bathrooms are literally a two second job because there's nothing to tidy up.
Wash dishes + sweep kitchen + declutter bathrooms + 5 min tidy up (which starts off hardly making a dent but over time can be really effective).
It's nothing hard and actually all of us fill the dishwasher and it's DS1's job to empty it so it shouldn't be difficult at all 
I just find habit forming really tricky. It took me decades to train myself to remember to clean my teeth every day
I do like the idea of a daily routine that can be built on. But tend to feel a bit despairing at things which get SO bad if you just forget them for 2-3 days. Dishes math (etc). Argh.
Maybe I'm being a bit hard on myself because I did go around and fill up the DW and wipe the counters, and the counters were noticeably less filled with random crap even though I had initially thought the kitchen was a disaster zone.
WWW so true she is very relateable. I think a lot of people have these kinds of thinking errors she describes, like the one where you tidy up by putting things into piles but then get interrupted by kids or whatever and the piles never get put away, thereby creating more mess. I have started the "Take it there RIGHT NOW" rule and it does mean that the little I do stays done, instead of me doing a lot and then it getting undone immediately.
