You are leaving a bit more on the surface. The vacuum method gets them very clean. It's useful with a lot of 7" records, the dust from the edges of the cheap paper sleeves and the way they're handled in the factory means they can be quite dusty/dirty.
It does just leave you with pressing flaws to be disappointed with. Sometimes it's better to just enjoy the records. They don't stay clean for long.
I carefully wipe mine with microfiber cloth with a washing up liquid solution on it, then dry it off, then wipe with IPA. In theory a microfiber cloth should get further into the grooves, certainly sound and look better after a wash anyway.
I'd rather avoid the risk of running them under the tap.
