So what do you guys use to get the fluid leaks off the driveway?
At HR girls house, there are some puddles forming. No, it is not from SeaCoupe. I swear, this w/e, I'm going to put cardboard under everyone's car to catch who it is.
Meantime, I want to get the spots off. Any advice?
An engine degreaser (or solvent like brake cleaner, wd40,carb cleaner etc) and Oil-Sorb would be the way to go.
Last fall after changing the oil on the motors of my boat (2 - 5.7l v8's and 8+quarts of oil) I put the oil changer (A 5gallon bucket with a pump on top) in the back of my truck planning to dump the oil in containers when I got home.
I got home late and decided to do it in the morning not realizing that at some point looking like about the time I drove up my drive, the bucket fell over and all that oil spilled on my drive. I dumped oil-sorb all over it and cleaned up the bulk, then used a degreaser and more oilsorb after. I thought my driveway was basically ruined but I can't even find the stains anymore.
Acids tend to etch concrete and take off a top layer.
Some years back, I used muriatic acid to eat up the excess grout I couldn't sponge up on a porous ceramic tile I put in my house. Nasty stuff.
Yes. I use MA on finished concrete when trying to bond mortar to it. Depending on the driveway though, this might not be too bad. Would still be a last resort.
Always seal the face (not the edges) of porous tile before grouting. Will save you a lot of elbow grease later on. I learned this lesson after installing a nice slate back splash for a customer. Ended up having to go over the entire thing with a little wire brush (golf club brush from my golf bag) in order to get the grout out of the crevices. Luckily I was able to do this before it set up.
I picked it up at the local hardware store. It's cheap. If I recall, about $3-5 a bag. Took me less than 2 bags to clean up all that oil.
It's similar to cat litter, but with properties that help it specifically grab oil molecules without the crap that makes it like cat litter. Cat litter is just absorbent but I don't think it breaks down oil.
Most marine stores carry oil sorb blankets and rolls for spills in water and bilge. Don't know if they sell the granules.
Ed, I actually took home from work some "institutional tide" for cleaning the concrete floors in the garage. It's not the same tide you use for laundering clothes. In foodservice, it's used for mopping floors because it cuts grease almost as good as grease cutting chemicals. Anyways, I scrubbed down the spots with it and a push broom. Let it sit there for 10 mins and repeated. Then I covered area for 2 days in backing soda to lift anything extra that got into the concrete. No joke, repeated the tide scrub and hosed it down after that. Now I can't tell where the puddles were.
