Any advice for cleaning up a typical garage floor? Stains include nearly every car fluid known to man

if you're using a powerwasher.... just get some dish detergent & let it soak in really good (scrub it in if you want)... it does really well. (I've mostly used it for outside 'typical garage floor stains,' though... that way the rain is free )

gasoline for tough spots (make sure the place is well-ventilated and its not too close to the heater, lol)

^^^ yeah... "purple stuff" works wonders, too. Your hands will start disintigrating if you work with it for to long

if the typical one is the concrete with pores, then its impossible.

unless someone has done it first hand. ive tried scrubbing, gas, powerwashing, brick and kitty litter...

^^TSP works.

Seriously, get you some concrete cleaner in the powder form and use it LIBERALLY. I usually wet the surface well and then sprinkle the stuff heavily. Let it sit for a minute or two and then work in with a broom or a brush. Keep it wet for about a half hour (DO NOT LET DRY), and then rinse off with a jet of water (pressure washer is even better).

Muratic Acid, works better than anything else listed so far.

3/22/2007 6:29:59 PM

dude... no shit hydrochloric acid works

so does a fucking 2000lb bomb

3/22/2007 6:39:09 PM

i second muriatic acid

fill a garden sprayer with muriatic acid and spray the floor with it, use an acid brush to rub it in and then spray down with a hose

^^its not that bad, you can even get the stuff on your hands and it doesnt even bother you that much

I have used some from of granulated concrete cleaner to clean up a heavily stained driveway. Wet, scrub it in with a good brush, wash off. Works quite well if you don't mind some scrubbing.

yep, muratic acid ftw. works well on unsealed concrete, cinder blocks, etc.

if you've got any sort of sealer on it, one of the other methods mentioned will probably work fine.

if you use muratic acid, use vinegar to neutralize it after youve finished cleaning

otherwise it will keep eating away at the concrete

especially if you are preparing the floor for sealing

how exactly is acetic acid supposed to nuetralize muriatic acid?
