Docks must be routinely pressure washed or they become slippery and ugly from black algae and small spills. They often have oil spills, fish guts, beer, fuel and even sewer tank liquids on them. Obviously, do not want anyone to fall into any of that. So what equipment do you have to do to get the best results. You really need a good pressure washing. The best thing would be to have a pressure washer hot water, if possible, but a cold pressure washer will run. You can use a stiff brush or broom, even perhaps to clean any dirt stuck in the bird droppings when using the pressure washer. It is recommended that you use any soaps or cleaning products and is likely to run directly the right to water that cause environmental problems, possible fines for you.
So please avoid any soaps or cleaning products, but may be tempting to use them. Good old-fashioned elbow grease will take care of the situation. If you are a contractor and are doing for a living, you may want to bid this by the hour or by the job. Either way you always make the most money and keeps everyone happy. Always be fair price with the owners of Marina, as they can send a ton of boat washing and detailing clients, you can even consider it as a freebee to lock in the references to the best of the navy, which is what my company does not. If you use a pressure washer hot water is going to work better and be faster. We recommend using a Hydro-Twister unit to ensure consistency and accelerate this process to the point that not even seem like work any longer. It has been our experience that usually can clear the docks at a rate of 800-1050 square meters per hour using 3000 PSI at 4.5 to 5.5 GPM in a wash once.
General maintenance routine or repetitive such as a monthly service near the sea over 1800-2200 square feet per hour. Inland areas about 2000-2400 square feet per hour for general maintenance and cleaning time will depend on the accumulation of moss, etc. It takes a little work on the docks then salt water lake of fresh water springs River. If you are washing a pier where fish and seagulls accumulate expected to decrease by half the area clean for hours and hope the smell of fish will be penetrated by the use of any cleaning with hot water.
