So whats the thoughts on the d101 as a interior cleaner for filthy vehicles? the reason im asking is cause i hate having to use so much of the expensive cleaners like wolfgang and blackfire just to get a work vehicle cleaned that`ll be trashed in a week to a few months, and with the cost of 2 gallons about the same as 1 of blackfire interior and them being dilutable to strength i need sounds really appealing. Like the other day when i did the sleeper semi interior i went through over a quart of cleaner just for walls and such.
