After a failed print, I just run a Vat Cleaning for 30 seconds. It will light up the whole base and create a thin sheet of cured resin you can just lift up. Makes things so much easier.
And honestly... I've found emptying the vat by tipping it to be messy and annoying.
I switched to something like this:
Fluid Syringes

Get as much resin out as you can... and then you can tip it to a side and siphon out more. Then just wipe up the leftover.
