Re: clean cylinder walls

You should really hang on for Corm to answer, as he really does know everyting.. but I got my piston out by soaking in in cola, yes coke.. After about 2 days it just dropped free. I would presume you have to be careful as this is a acid and too much time could cause other problems.<br /><br />I'd check with corm on this one.<br /><br />Dave

Hi Firebird,<br />A weak mix of muric acid. I have also used Zing, a alumninm boat hull cleaner.It has a<br />blend of hydrochloric and sulferic acid.<br />Also a weak mix, but you have to watch it.<br />rinse it with bakeing soda and water and then<br />oil the bore.<br />...watch your clothes...corm
