I have been using this for years now. Will make your power cord look like new without destroying the rubber. I tried to post a pic of the seats I cleaned with it on a Formula I bought this winter to replace the Intrepid Ian ate! One side of the seat is white and the other grey! Amazing product! Make sure to ware heavy rubber gloves suing it and change rags often keeping the rag wet with product works the best. It took about 1 1/2 cans to clean all the seating of the 33 Formula. Works on plastic as well. Turned the plastic molding on the Intrepid rub rail from grey looking to white as snow! Be careful on colors! Don't rub to hard too long! Try in a small spot first. It used to cost $20 a can before the new owners bought it. Still worth it though as nothing else comes close to this stuff.
Flitz metal polish also works on plastic. Try it on on your strata glass or acrylic windows even by hand without a buffer it turned out amazing.
Happy Cleaning all!!
