Dunno if it's detrimental to the rubber floor (so far everything is fine) but I've been using Wesley's Bleche-White to clean tough messes off the floor of the E. Things like soda spills or just general funk comes up pretty easily with a few sprays of Bleche-White. I usually spray it liberally on the floor then use an old towel to wipe it up. I don't have a scrub brush or else I'd use that too but it works really well. Just thought I'd pass it along.

I use good old 409 , glad yours works :)

i work in the automotive industry for a utility company, and we get that at work (internal material code), and its awesome!

ive used it on pickup wheels, and tires, and it cuts grime and dirt without a challenge. even though my vehicles aren't personal, and honestly we don't treat them like our own.. so i don't know if its dangerous to clear coat finishes on nice wheels, but black painted wheels, steel wheels and so forth.. works great.

and afterwards, since it cleans the wheels and tires big time, the tires are "thirsty" and soak up some protectant really well. whatever your pref. is...
