Battery stain sales track
Selling Battery Stain Removal jobs: 

"Battery stains are unlike any other stain a homeowner could have. Battery stains are 31-50% sulfuric acid in concentration and even though concrete is alkaline, it does not have the power to neutralize those stains. So, the acid remains active for many years. 
Every time it gets wet, the water reactivates the acid, which dives it deep into the concrete and spreads on the surface. This is why you 
see the orange battery burn run down the concrete. EPA, stormwater compliance and regulatory officials consider these 
stains hazardous, corrosive, toxic and carcinogenic. Even when dry, the particles can be kicked up in to the air, leading to respiratory issues. It can also be tracked in the house, carpet, etc. (this is where I ask the homeowners if they have walked through it and then walked into their house... if they have, I will recommend to have their tiles and carpets cleaned). So, the active battery stains can eat through an entire 6" slab of concrete, promoting premature deterioration of the concrete slab, ultimate leading to a tear out and replace situation. Maximum fines for homeowners who have hazardous stains going into the storm drains can be up to $37,500 PER DAY.”

We can fully neutralize the battery stains, turning the sulfuric acid into sodium sulfate, which is basically as non toxic and benign as 
table salt. (You do this by putting down F9 Double Eagle Degreaser at 8:1, sometimes stronger). The stain will be put in check and never reactivate again or cause damage to your concrete unless you get more acid on it. 
White stains from the concentrated battery acid will remain, and you can normally get 85-95% of the remaining orange acid burn 
(realistically you'll get 99%). The concrete will be clean, bright and much newer looking.

So:
1. Battery stains are hazardous, toxic, corrosive and carcinogenic. Battery acid is 31-50% sulfuric acid and extremely dangerous.

2. The battery acid stain must be neutralized immediately into a non-hazardous state (use F9 Double Eagle, 5:1 to 8:1). F9 DE turns Sulfuric Acid into Sodium Sulfate.

3. Water will reactivate the battery stain. You can burn your feet if you walk through it and you don’t want animals or kids playing in that area. If the battery stains are white and dry, the flakes can turn into dust and become airborne. This can be deadly for your health and cause lung damage.

4. If not neutralized these stains will continue to grow and expand, reaching deep into the slab and the orange may eventually drain into storm drains. This will compromise the strength of the concrete and could result in steep fines to the homeowner.

~ A simple PH test can help confirm the acidity, alkalinity or neutral PH of the concrete. You normally want to test the “white” part of the stain as this will be the most concentrated acidic area.

Selling regular rust removal and fertilizer rust stain removal jobs

1. Rust will damage and oxidize the surface it is formed on.

2. Rust will continue to harden over time and become more difficult to remove.

3. Other rust removers will etch the concrete, permanently removing the cream and leaving a “scar.”

4. The only other options to remove the rust (on concrete/hard surfaces) is to grind, sandblast, bead-blast, scarify, coat, or tear out and replace.

5. All these options result in damage or are more costly than hiring YOU.

What’s the difference between F9 Double Eagle and F9 Groundskeeper?

Groundskeeper is a product to use if you don't have thick built up grease and oil, but you DO have oil stains just beneath the surface, dirt, tiremarks, shopping cart marks, light rust stains, coffee stains etc. this is a MAINTENANCE cleaner, which means accounts like Walmart, Costco, Drive Thru’s etc and anything with Industrial Strength Concrete- Stadiums, etc. this is not for residential concrete. F9 GK will get the concrete super clean, and that clean will last longer than if you used high pH cleaners. 

If you have thick oil, food grease and oils on top of the concrete surface, F9 Double Eagle is our "Double Purpose" Cleaner/Degreaser and Neutralizer. This is an excellent product to remove the thick and for concrete maintenance with an alkaline, high pH product. DE is also used to neutralize low pH products, like our F9 Efflorescence and Calcium Remover (F9 Efflo). For maintenance accounts where want to make the concrete "Pop" and keep them looking cleaner longer, use our low pH cleaner F9 Groundskeeper. For those types of accounts you could pretreat the thick stuff with Double Eagle, clean the oils down to the surface of the concrete, rinse off the oils, then use your F9 Groundskeeper over everything and surface clean. Dwell time is only a couple minutes and it doesn't matter if you use hot or cold water. Most guys try both products and see what works best for them. 

Groundskeeper pulls out caustics in the surface and subsurface levels and brings the surface pH back down closer to neutral. The chemical reaction of GK makes the concrete more white and has more of a hydrophobic action when stained. If it does become stained the stains release easier than when they are repeatedly cleaned with high pH cleaners. The problem with high pH cleaners is that they build up in/on the concrete and pull more dirt/dust/sand and grime into the surface. Even after cleaning, the concrete can have a dingy look to it but using high ph cleaners is definitely necessary for topical oily buildup. 

So basically, treat thick oils with DE first and clean them off. Rinse and while wet put down 10:1 GK or recommended dilution. Dwell 5 min and surface clean. OR, For maintenance cleaning sidewalks like Chic-Fil-A’s, wet with water and go 10:1 with F9 GK. Dwell 5 min and surface clean.

Hydrochloric Acid

Acid Q&A: Hydrochloric Acid

Let me tell you a little story. There’s been some talk lately about some guys using regular cheap, inexpensive Hydrochloric Acid for calcium or efflorescence removal. HCL is also known as Muriatic or “pool acid”. This is a common ingredient in many cleaners, but just because a professional cleaner (like F9 Efflo) has HCL, doesn’t mean it’s the same HCL that is in Hydrochloric. F9 Efflo has buffers, inhibitors, wetting agents and surfactants. Thinking you can just dilute HCL down and make your own cleaner can KILL YOU. One whiff of pool acid can land you, your contractors or your customers in the hospital. Ask me, I know! I used to use this stuff 20 years ago and have seen just how destructive it can be. We have had customers get sick from walking 100’ away from where we were working. In the early 2000’s I also personally caught a solid whiff of a very common industrial brick cleaner that had HCL… and here’s what happened. Again, this is from ONE WHIFF.

My throat felt itchy and my lungs felt dry. I was dry-heaving at night, experiencing extreme pain in my lungs, abdomen and throat. Couldn’t sleep, toss and turned all night. After on and off Dry-Heaving for 6 hours I had severe diarrhea and I started to have difficulty breathing. My body began to ache really bad so I laid down. I couldn’t get out of bed for the next 5 days. My body was hurting so bad I couldn’t move. One touch to my skin and I would scream in pain. It was EXTREME. I couldn’t move my neck and shoulders more than 1/4 “. I lost my voice for 3 days. It took about a week while the pain travelled down to my legs then back up to my neck and shoulders. After 2-3 weeks the final bit of pain went from my throat (after it went from my throat, to my lungs, to my feet and worked its way back up to my throat) to the back of my tongue. Then every day the pain would travel closer to the tip of my tongue, but I still couldn’t taste food. This must have been the last of the toxins finally making their way out of my body. The last few days of this experience (took about 30 days to recover) that the pain finally reached the tip of my tongue my eyeballs actually peeled a small thin layer of skin. Yes, actually peeled. I was blinking out some kind of thin eyeball skin.

During this month of joy I lost 18 lbs. I couldn’t eat solid food for the entire month and it all-together took close to 6 months to fully recover. And this isn’t even the whole story.. just most of it. I would never ever want ANYONE to have to experience this. And I am not the only one to have experienced this. I have see other people with other companies experience the same things. Or worse. 

This is one of the main reasons I created safer products. It was either get out of the business or make something that my employees and I could work around.

If you’re going to use HCL products for cleaning, especially Industrial Pool Acid, make SURE to wear a hazmat suit, proper PPE, glasses, gloves, boots, respirators, tape off and put up caution signs around the areas you are working.

Also, leave using regular pool acid, aka “muriatic” off this page. I sure wouldn’t want you or someone working for you to get hurt . Use it if you like but know what your dealing with.

Fertilizer season (Spring) is here, homeowners are fertilizing there yards and they are going to forget about blowing off the granules. Lazy lawn care employees will do the same, Get positioned to grab that business. You got be found and Craig will get you found.
