Need Help with interior cleaning.

Hello,
I have a very filthy car. I need help with a few things. when I vacuumed the floor it didnt get everything out. I went over it about 5 times and still nothing. I also was wondering if it would be alright to put armor-all on a Q-Tip to clean all the dust from the vents. Thanks for the Help!

not sure about the carpet, maybe use a shop vac? and for the vents, i dont see why not as long as it doesnt drip and run too much, even then i doubt itll hurt.

    The best thing I've found to clean vents and down in cracks is
  a new small paint brush like 1/2 inch wide.

spray all purpose cleaner on the carpets then scrub with soap....let sit for like 5-10 min....then vacume...that should do it

Ye I need Something with the carpets to, Filthy As can Be.

you could try chemdry, seems to work good on upholstery

I think i might try that the Paint brish ...

or a toothbrush will work decent, steam cleaner is the best ive found for vent but not everyone can get a hold of this device

To clean AC/heat vents use a cue tip with a dab of water.  To clean the carpets just use regular carpet cleaner and use a scrub brush

But what do you use to get stains out from the ceiling?
