i got coffee stains out of my dads f250 that he also had a cig fall and put a hole right where he spilled his coffee....i first sprayed blue coral on it and before i scrubbed i sprayed some shout....coffee stain came out and the burn looks good minus the missing ring of carpet lol....but no kidding, mix the 2 and it will work. also, they have some deep cleaners in airosol cans at autozone with oxyclean...i bought some but was afraid to try it because of colorfastness....my dad tried it on our old couch thats in the attic (20 year old couch) and it looks really new now...ill try to figure out the name of it...oh and that stain was there for a good 2 years....he bought the truck when it was 2 years old...hes had it for 3-4 now and its never been cleaned besides vacumed maybe once a year

edit
after lookin at that rear mat again, i think i see some brown near the left side of the mat....it can be taken out....

 

personally i said screw the cleaning the salt out every year and got a set of rubber floor mats for the front of the truck that i put in it in the winter and now i dont have to clean the front mats each year, or at least not from winter salt and dirt

 

Rubber floor mats FTW....I have Superman ones.

 

the blue coral should bo foamy after it exits the airisol can...it should have a tip on it like this, its like a scrubber




dont be afraid to be generous with the blue coral....what i did was i got it pretty wet with the shout first and immediately applied the blue coral....then i scrubbed pretty good....have a towel handy to wipe dry kinda like its your hair...you may have to do this 2 or 3 times....i got the coffee stains/spills ect out 1st try though....i hope it works for ya...if not, go back to autozone or w/e and ask them for their best working stain remover...try it on a part of your carpet first to check for colorfastness... and about rubber mats, i would suggest them...i just put them over my carpet mats...there are some real cheapies though, i got mine at walmart and i liked them the most....they have straight lines pretty uniform in configuration probally 1/2 inch deep....theyve caught all the mud, sand, dirt ect very well. i wouldnt get the flat rubber ones....atleast not for me being in the weather conditions i get in

 

my bottle looked like this one but had the scrubber from the 1st pic...im sure its the same..

 

yea the rubber mats i have catch most of the **** i track into the truck, but i only have them in it in the winter when i track alot of **** into the truck, i usually take them out in the summer bc i like the carpet mats that i also leave underneath better, and yea you need the deep ones or else they dont catch **** and are almost like having nothing, it just concentrates the dirt aroung the edges of the rubber mats

 

so, results?
