I threw all four in sideways and filled the water to the top, I used hot water for wash and cold water for rinse. Yes I used detergent.

 

Did you bother vacuuming them first to get the larger debris out? Or did you just plop em in there straight up?

 

So it didn't hurt the rubber backing? I like the idea! Quite a few years ago I washed some spoke wheel covers in my dishwasher that turned out awesome but my girlfriend could not believe I was washing car parts in a dishwasher.

 

Im trying it..
Its amazing what us car guys do with ovens, washing machines and dishwashers... Prob the only few times we ever used them..lolol

 

Plopped them right in.

 

I never thought of that! lol

 

Don't forget freezers. Years ago when I raced motocross, my wife came home while I was in the process of resleeving an aluminum cylinder in the kitchen.
I had the cylinder in the oven and the steel sleeve in the freezer. At least I wasn't using her oven mitts.

 

Just threw em in, I'll share my results later. What a fantastic idea though!

 

I can't say I've ever tried it, but it sounds like a good idea and would probably net some decent results.

This is what I purchased for doing customer interiors. I needed it to be fairly small as I do a lot of mobile detailing work and need to lug a bunch of equipment with me. It works extremely well.

 

I'm sure washing these in the washer machine wears out the rubber backing and will probably cause it to crack down the road. That's the only thing keeping me from trying this.

 

i just lay mine out on the living room rug and hit them with the bissel. its alot faster than the washing machine and no damage to the rubber back. i tried the machine before with some mats from another car and i had the lil rubber spikes all in the bottom of my machine.

 

My rubber is fine, I was actually planning to buy new mats but just tried this instead.

 

I always wash my bathroom rugs with the rubber backing in the machines. The washer doesn't seem to cause any probs, but the dryer really wears the rubber down over time. I have a front load washer which may help though.

 

I definitely would not throw them in the dryer.

 

i've had hot water destroy previous cars' floormats. i do this all the time, in cold water.
