Salt Off Protector with PTEF is specifically formulated to quickly and effectively remove salt deposits from metal, fibreglass, plastic or painted surfaces. It contains special PTEF polymers that bond to the treated surface to help prevent the formation of future deposits. Depending on the application, Salt Off can be sprayed directly onto the surface to be treated and then rinsed with fresh water, or simply left in place. The formula is safe for use on all boats, vehicles, trailers, marine parts, engines, fishing and dive gear and more. It will not etch, stain or damage metal or plastic surfaces. It is ideal for removing salt water deposits from boats and fishing gear, as well as for protecting cars or trailers from the damage caused by exposure to road salt. Salt Off is also very effective at protecting marine engines used in salt water; when used with the Salt Off Applicator, it will flush deposits from the engines cooling system to help insure maximum performance and service life. The Applicator can also be used to more easily apply Salt Off to large areas. Salt Off is available in convenient 650ml spray bottles as well as in concentrated form in 950ml and 3.8l containers. Spray Salt Off on surface to be treated. Let application soak into salt for 10-30 minutes. Heavy salt build up may require scrubbing with a brush. Rinse and let air dry. Use Star brite Salt Off Concentrate (available in 950ml #93932 and Gallon sizes #93900) to refill this bottle. Add 30ml of concentrate to empty bottle and fill remainder of bottle with fresh water.
