I do it similar, but a bit easier I think.
Instead of taking the big hoses off and trying to reach in there like that, I simply unbolt the top unit and pull it up. I use Q Tips and 99% alcohol. Much easier actually.
All you need is a tamper proof T15 torx bit available at most any auto parts store.
It allows you to clean in all corners, sides, areas etc.
Then carefully drop it back in and go.
Resetting the puter is always a good thing to.
