Wearing rubber gloves and working in a well-ventilated room, sponge a small amount on, then off, to test the reaction. If the logs respond well, continue cleaning. Other cleansers, such as Simple Green or citrus cleaners, may pack enough power for your needs.
1 The cost of hydroseeding at Always Green Hydroseeding depends on the seed choice. 2  Quick Lawn, which uses Perennial Ryegrass, costs $0.10 per square foot. 3  Athletic and Park, suitable for home lawns, parks and athletic fields, costs $0.12 per square foot.
For an acre or more, the rate is about USD 0.08 per square foot. This requires about 0.1 gallons of slurry sprayed over a square foot. So the cost per acre at that price, would be about USD 3485, which is quite reasonable.lso, contractors offer a discount on the per square foot price, if you are covering a larger area of land. More the area to cover, lesser is the price. If you plan to hydroseed a lawn to cover about 10,000 square feet, then the cost offered by contractors could be around USD 0.11 per square foot.
