A nice summer project - congrats !

I use a bucket of water and some nifti. Use a wet rag, spray on some nifti (on to the rag) and away you go - rinse and spray. Try a few test spots first.

Did you get legs with it ?

All the electronic boards are here - including displays ;

I would probably buy all from one source.
