Against my better judgement I used Stoner More Shine on a brand new set of tires last summer and now the tires are exhibiting that ugly brownish patina after I tried brushing it with a stiff brush with soap and water. I also tried using a 1 to 4 solution of Super Clean degreaser as well will minimal success. Is there a good way to get the rubber back to original color like using isopropanol alcohol or silicone ?
