keeping my garage clean,

[jojokoko]

I am having my car washed with a portable pressure washer (Worx) and a two bucket method afterwards in my garage, except i dont have proper draining installed ATM, is there is a way or something i can do to keep my garage (6x8 meters) clean while still being able to wash the car with a portable pressure washer and two bucket method ?

I don't have a drain either.
I use a foam squeegee and keep it swept.

I use a squeegee too and I use an awful lot of soap and water. Squeegeeing turns out just fine.
