The scary thing is, I'd bet a lot of us have done similar (maybe not as bad of offenders) things..
When I was a bachelor, I had a ground level apartment, and when I was rebuilding the motor of my car, I rolled the engine stand into my kitchen (with engine attached) so I could continue to assemble in a relatively clean place (better than outside!) over a hard floor. Now, I know that sounds pretty bad, but, I did cover the carpet with lots of newspaper before I rolled the engine stand to the kitchen's tile floor to avoid stains, and also the only parts that came into the kitchen were clean parts that were being assembled.
I've also once before (before I had kids!!) taken carburator parts that had just been submerged into the carb cleaner can overnight into my bathroom to rinse out the carb cleaner in the sink. I took super anal-retentive precautions to avoid drips, stains, or damage to the house or the inhabitants, but still- if I tried that now my wife would kill me. Tell you what though- those jets, needles, screws, float bowls, vacuum cylinders, vacuum caps were all SPOTLESS!
