i have a steam cleaner, 2 of em, low end style, were under 100 usd each, one steams clothing
, ceilings, overheads, and soles, the other does soles, cushions
and whatever i buy additional parts
to steam clean, including "windows"
i donot have one for engine
these keep flying pests at bay. no fleas no ticks no beetles, nothing left. i love em. and i am in tropics where critters proliferate without help. helps with pet bedding and other issues that get overlooked.
