But what happens when your system is held together by the rust?!!  =)
I've always been impressed with what CLR is able to do but tend to want to use it full strength on tough jobs.  This appears to just be a concentrated version of CLR so that by the time it's diluted in your system it's still plenty strong to do the job.  My biggest concern is on my old bulldozer that's held together by rust, what happens when I dissolve the last of it?!!  =)
