Chemical For Concrete Parking Lot

Yes, repeat business is important. …I agree !

and YES

You can have repeat business while making 1 to 5,000 dollars an hour if your services have a Perceived Value to your customers.

We do have repeat customers and yes, once in a blue moon, upper management gets replaced and they seek out other companies. They always return, except this time, the cost of doing business rises.

You see, we never raise our prices execpt for fuel costs which is less than $500 per jobsite. We have a few customers that we have been servicing since 1988. They’re not garages since we started them in 1989, but none the less, we do not raise their invoice price. If they were to cancel service, than decide to come back, we would quote them a new price based on todays bids. This locking in the price speaks volumes to the customer and as long as the service and workmanship stays high, they will never leave.

Now I can only speak about our customers.

With our customers, we make sure there is a meeting of the minds on how we accomplish the cleaning and the depth of the cleaning and agree to a price accordingly. I have customers that are 27 years working with me come this Dec. In that time, I have only lost 3 customers( 2 because the Business moved out of state and 1 because upper management’s friend got in the Power Washing Business).

But what comes with that is service …

For example…If they call today and want it done by tomorrow, it’s done. In rare cases, they have called me in the late afternoon and that evening… we was mobilized on the site with 26 men working with 8 washers and two 68 gpm filtration units with permits in hand. Very few business can achieve this level of repsonse in that short amount of time.

We can clean up to 280,000 sq ft in a single work day. That includes walls, colums, Stairs, EVERY square inch of the floor with full flow filtration with permits in hand.

That’s justifiable, big crews, amazing response time specialized for that size project… I was thinking charging $1,000 per hour solo… See I’m small time here…

Off topic but is it possible to remove oil stains with a cold 4gpm pressure washer/surface cleaner and purple power degreaser? My limited knowledge is showing here and I’m ok with that. Searched online and didn’t come up with much.

Yes, and No
Depends on how fresh the stain is and has it been baking in the sun letting it seep deeper. The type of oil, how porous the concrete, ect also effect the results.

More than likely you will have a shadow remain especially with cold water. Also will take multiple treatments and pass to get most of it up. Best way to tell a customers is you can remove the oil but a shadow will remain.

I just did an emergency spill the other day where an oil recovery truck over flowed. It was a mix of oils and did the best we could with cold water only. I let them know there would be a shadow and we remove a lot of oil, but you definitely know something spilled in that spot.

One thing i wish i would have used would be caustic on this stain, probably would have helped a little better but used ebc, red raider, and purple power( at different times) and it did good

What do you mean by caustic?

Basically caustic means it has corrosion properties mainly a Sodium hydroxide mix. Draino, and other drain cleaners are sometimes caustic mixes in a bottle that your paying 100% mark up on.

Some make their own caustic mix so they can go as strong as they like and other buy pre- measured mixes from the suppliers (you still have to then mix it your self). Products like:
CCX
Bd20 (butyl based/non caustic)
BD200 (butyl and caustic),
WD25 (butyl based and caustic stronger than bd200)
and a lot of others

Caustic is good for food grease, oil, tire marks, dumpster pads ect. from just reading, a lot of people have slowed down on using caustic mixes because of its negative effects it can have. If its a one time cleaning then its not a bad idea to use some, but some have noted using it can cause an area to get dirtier quicker. Also can strip the paint off door, etch metals, potentially scare some concrete and other surfaces if too strong. Rinsing is very important, and really need to make sure an area is “flooded” once done cleaning. It can be dangerous to handle as the mix itself can heat up to 100 degrees, which is why its also good for cold water units.

If you doing monthly contract work its best to just used, ebc, red raider, or another not caustic or butyl base degreaser. The area “should” stay cleaner longer, and less risk to other surfaces around like door frames and just safer to handle.

If your doing a somethings oily and nothing for the mix to really splash up on then using a caustic mix might not be a bad thing.

Ironically never had to use the stuff, ive always used non butyl non caustic degreaser I just read a lot. I dont like oil jobs, because even if you get the oil up the shadow still looks bad.Some customers expect 100% removal, and for you to make it look brand new. I will definitely be buying caustic though just to have some on hand.

Thanks!

Caustic won’t get oil shadows out of drive thru lanes or parking lots…it will lighten it up a little, but it is still there. Once those stains set…they are there to stay.

And, as far as drive thru lanes in general…they are just a dirty affair and you aren’t gonna make them look clean. I just did a DQ drive thru last week using EBC…looked pretty good the next day…I just drove past it a few minutes ago and it looks like crap, again.

@JimLuke Hey, you seem to do a lot of concrete. I asked a question a week or so ago regarding concrete oil stains and you gave me some good advice. I changed the process a little bit and it got the stain out 99%. I know it’s frowned upon but I used hydrochloric acid (31 %) let it sit on the stain for 15 seconds, rinsed quickly, then used zep purple full strength in the stain. The hydrochloric acid opened up the top layer of concrete without to much damage and allowed the degreaser to penetrate down into the concrete. Repeated that process three times and it came out great. Have to rinse good between hydrochloric and the hydroxide as they neutralize each other. Have you done anything similar? I know it’s not feasible for large areas but for a stain or two on a driveway it’s not to bad

I have not…but I might give it a try on a residential job. Thanks

Like you said…not practical for something like a drive thru or customer parking area.

That’s sulfuric acid right?

when is your next parking garage cleaning event?
