Oil Removal Expectations

Using hot water and ebc. The big trouble is with the drips from trucks. Im wondering if I am doing something wrong. The job I did this morning was a first time so Im not sure how long it has been there. Whats your oil removal process and do you expect to be able to handle any oil?

Im downstreaming the ebc from the jug. I know the dilution is weak but on the last job I hit it a second time with a pump sprayer at about 25% and it didnt really make a difference.
 
One thing I have learned over the years about removing oil stains is that always use the word "attempt to remove oil stains" in your proposals. It doesn't matter what chemical you're using or if it's residential or commercial. The oil stains could be there for 10 years and the customer says they have only been there 2 years.

I've had great success using EBC personally but I never guarantee 100% removal results on anything.
 
Dan, the stains look to me as if they've been there a while. My best results on stains like those are to apply EBC at maximum mix strength and brush it in. If you see the EBC turning brown you'll know that it's pulling oil up out of the concrete. If you're not seeing the EBC turning brown, the stain is not going to come out.

If the EBC is turning brown, spray the stain again and leave it to dwell for a least 24 hours (no rain in forecast). Return and hit it with hot water.

As Vince and Carlos said, no guarantees!
 
Just got back. The reason I went back btw is some miscommunication about what all the mgr wanted, Bid right for what I thought she wanted, bid low for what I did, but shes happy now so live and learn.

while there I hit it with some stronger ebc and didnt see any change.

What about the stains tell you theyve been there a while?

THIS is why we do MAINTENANCE cleanings. Who would stain a white shirt, leave it for years then throw it in the washing machine and expect it to be new looking. You address the problem asap. One time or sparse cleanings make for sad managers.

Also, I had this at another restaurant. The front door still had some dark discoloration to it. Anyone seen this and know what it is? You can see a big difference in this picture but you can also see some dark streaks even in the clean area.

On the last pics of the entryway. It looks like a broom finish. I would try to surface clean in different directions. North&south east&west. The dirt and stains may be deep down in the broom finish.
So if your surface cleaner is spinning clock ways, you may be just cleaning the left side of the groove if you are going with the finish.
The clean side defiantly looks better!

The stains on store/restaurant fronts mostly come from the inside. Mainly because the employees do a half a** job mopping. Also it indicates they need the interior floors pressure washed lol
 
The black stains going to the dumpster might be hydraulic fluid stains which are very, very hard if not impossible to get out once they have been there a short time.

I have tried many, many different kinds and strengths of degreasers with very hot water on fresh hydraulic fluid stains and the stains did not budge at all. Tried some that were about 2 hours old and nothing came out at all.

Motor oil is a different thing, if it is within a couple weeks to a month then usually I can get it all out but if they have been there years, I tell them that I can make them look great but there will be a permanent stain/shadow left there, still looking for the miracle oil stain remover but have not found one yet.
