Dock Stain Remover

Oil stains on a dock prematurely ruin the concrete. They can also be unsightly and, ruin the beautiful marine setting as well.

Oil stains on a dock prematurely ruin the concrete. They can also be unsightly and, ruin the beautiful marine setting as well. DE-OIL-IT is the powerful green dock stain remover.


Handheld Equipment:
Mop, Spray bottle, Pressure can, Backpack sprayer, Floor scrubber.

1. Dilution Ratio: (for concentrate only), full strength up to 1-part product to 3-parts water. The 22oz. spray bottles are ready-to-use.

2. DE-OIL-IT is water activated and once applied as a dock stain remover, it needs to be kept hydrated to work. When water has evaporated, solids in product remain dormant until rehydrated. If rehydrating, do not rinse away the solids. Spray water lightly or just wait for rain, morning dew, or the next application to reactivate the solids.

3. New stains are removed instantly. Older stains take longer and may require several treatments over a several day period. This will depend on the age, amount and viscosity of the petroleum present.

4. Saturate area(s) thoroughly with water prior to application.

5. Apply solution liberally onto the stained area(s). If using a mop, simply slop the DE-OIL-It solution onto the stained areas liberally. Best to apply at night, mark off area for traffic and retreat area daily or weekly until the stain has completely disappeared.

6. For commercial use, continue treatments by including DE-OIL-IT as part of your regular maintenance program. After original stains are removed, reduce the dilution ratio to 1-part product to 20-parts water.

7. For quicker results, agitate heavier grease build ups (solids) with a bristle brush.

8. To speed up process, cover area with a rubber mat or a dark sheet of plastic. This will trap the moisture and keep the solids active.

Keep Product away from children. SKIN CONTACT: protective rubber gloves not required but recommended; rinse thoroughly with water until any irritation subsides; application of skin or hand moisturizer recommended after use; if irritation persists seek medical assistance. Not recommended for use on asphalt in concentrated form less than 5:1 product to water dilution – in prolonged and frequent contact on asphalt De-Oil-It can strip surface oils and/or break down grooves into the asphalt.

De-Oil-It will clean oil and fuel spills on docks so throughly hardly a trace of stain will be seen. For Marine Applications your use and how you apply De-Oil-It and disposal of the cleaning process may be affected by government regulation regarding hydrocarbon contaminant (oil, grease, fuel) spills; please follow posted guidelines.

Note: using terms like “hardly a trace” is contributed to De-Oil-It’s “colloidal micelle formation” technology that reduces the surface tension of oils, grease, and fuels so that they do not stick to surfaces. This terminology also applies to the correct use of De-Oil-It that includes but not limited to appropriate amounts of De-Oil-It, water and air (both are activators of De-Oil-It), possible re-application (best guided by not only visual review but also testing of contamination levels), and perhaps government regulations that may affect how you apply and dispose of the cleaning process. Also hardly a trace refers to the application, and possible re-application, of De-Oil-It to further degrade hydrocarbons which in time is augmented by natural occurring bacteria

** Detoxification / non-toxic means an end result correctly applying De-Oil-It by following the recommended dilution guide, availability of water and oxygen (the activators of De-Oil-It), and being patient (in time naturally occurring bacteria in land and sea will enable the degrading of the hydrocarbon contaminant into smaller simpler molecules of carbon, hydrogen and oxygen versus a complex fully attached hydrocarbon molecular chain that is toxic). Detergents and solvents can only partially breakdown the hydrocarbon chain and their degrading action is weak in the sense that the separated simple hydrocarbon molecules re-bind, leaving remnants of toxic compounds that are harder if not impervious to natural bacteria final degrading; one consequence of this is to encapsulate the oil making it heavy and sink to the ocean floor – therefore in comparison to detergents and solvents, De-Oil-It starts as non-hazardous completely organic ingredients that are found on the Food and Drug Administration’s (FDA) GRAS (“Generally Recognized as Safe”) List, and can transform hydrocarbon contaminates (oil, grease, fuel) into an inert (non-toxic) state. De-OilIt’s “colloidal micelle” technology more successfully breaks down the complex hydrocarbon chain, separates smaller simpler hydrocarbon elements, and De-Oil-It then more tightly binds to the broken down hydrocarbon chain parts so they do not reform as is the case with detergents and solvents. We are a non-detergent, non-solvent, organic only formula that works.   We are here to help you understand remediation methods including how much agitation, working with soil and sea, as we have a wealth of experience regarding successful approaches and final outcomes.
