<p>[QUOTE=&quot;Just Carl, post: 126446, member: 4552&quot;]I like Mikjo0&#039;s method the best. The only thing I would add to that is to spray them with a clear laquer after that to have the results stay that way. </p><p>&nbsp;&nbsp; When I was a kid my Dad owned a gas station. It was in a large trucking area so one of the things he got involved in was fixing truck flat tires. There is a large metal rim that helps hold that thing together and he used to pour Coke on this to free up the tire and metal rims. It only took a little while and they would break loose quickly. </p><p>&nbsp;&nbsp; I truely doubt that anyone would carry Coke with them to a crime scene to remove blood since there are so many more practical and economical products available. The Coke rep had a sence of humor. Same is true for putting it into a sinck to clear out blockages. It appears that just about all chem classes have the experiment to show the acidic properties of soft drinks. However, when we did it we tried different metals for the bolts and the soft bolts made of annealed iron only partially dissolved. Bolts made of high grades of Stainless steel, such as 440 or higher were hardly effected at all. The chem teacher should have explained that. We would have used the meat method but thought cooking it would be more advantageous to our experimenting on weight additions to the human body.</p><p>Oops. Forgot. True Mountain Dew is the one with all the caffien, not high in acid.[/QUOTE]</p><p><br /></p>
