I bought a California MF wash mit & tried it out this weekend.

I used to use MF covered sponges for washing.

My observations on the mit:
~Holds much more water than the sponges
~Creates much more foam/bubbles as you glide it over the car
~Larger surface area shortens cleaning time
~High water retention makes the mit heavy = good workout
~Size makes it impractical for cleaning small areas like door handle recesses.
