I see alot of people are starting to use steamers for detailing Interiors and Engines etc.., so my question is what materials or parts on the interior and in the engine bay is the streamer safe on, and what materials should be avoided. Do you literally just spray the streamer directly on the interior parts and wipe or are there tips to using them inside? Also in the engine bay, there is alot of computer, sensor etc.. type parts, is it safe to just spray everything down in the engine bay or are there parts to avoid. I have a portable steamer to use which is definitely not as powerful as a commercial one, but it should get the job done, i just don't want to do damage to anything, so i figured I'd ask before I whipped it out and go crazy. thanks for the help!
