After completing my playthrough on stream and getting all achievements, there were a few that I felt could be worth explaining in a bit of extra detail, though the descriptions in Steam are pretty good.

Self-explanatory, you just get these from completing the levels, as normal.



First job, pretty quick, nothing special about it - though the rear hinges on the door were a pain for me.


Second job, cleaning all the components in the rear was both extremely satisfying with all the dings, but also a bit frustrating with the angles you have to hit things at to get them all clean.


Third job, the inside of the clock tower was the most fiddly part, with all the components, but was pretty fun to see the working mechanism.


Fourth job, nothing too complicated, though some of the upper walls seemed very unforgiving on what was needed before they would ding - had to use the dirt display to highlight things not visibly dirty to me.


Final job and really fun, with lots of moving parts, just a bit annoying with the angles needed to clean all of the small components.

After completing the Time Machine, and it does its disappearing act, you need to remain on the map for a bit longer - I timed it at a minute after it disappeared that it came back, and credit for the achievement was given slightly later, after the car had stopped fully.



Did this naturally in my playthrough without realising it was an achievement - there is a prompt to interact with the bell hammer, so what else are you going to do but hit it?



The Grid Wall is the top-most feature, I got this naturally as I always like to clean from the top down, generally. I wasted a bit of time doing some parkour to get up on top of it, but then got the ding with a large amount of wall still remaining, so I don't think you actually need to clean the top side to get credit.



While technically missable, the game itself prompts you about this one through the pager messages. Just stand on the red tape cross on the road in front of the theatre - not sure if you have to have first cleaned the projectors, but I had.



The Flux Capacitor and its Particle Colliders are in a housing at the front of the train, above the 'Time Loop Knife'. The housing is quite a large piece so there is not too much chance of accidentally cleaning anything else while doing this, but I was standing right in front of them anyway.
