Some of the posts on TFP regarding de-scaling a SWG with acids seem to have conflicting opinions. In one post, it's stated it is safe to use 6% vinegar as it will not damage the rare-earth metals on the plates. Another post states "all acids will damage the plates". Asking for clarification here... does vinegar damage the plates, or no?

I bought a gallon of 30% vinegar at Home Depot yesterday. I was planning on diluting this 30% down to 6%, so again, is this safe for the SWG to do this, or no? I would try the popsicle stick trick to manually clean the plates, but I have a RJ-45+ cell where the plates are offset from the inlet/outlets, and makes getting a stiff tool in there to do the job very difficult. Asking for a friend... Thanks in Advance!
 
All acids will have an effect on the plates but to varying degrees depending on the acid's diluted solution PH level. The lower the PH, the more damaging the result but the less effective at cleaning. It is a trade off.

I have always used muriatic acid diluted 4:1 (~6%) even on a cell that lasted ~9 years so I know that level is not all that corrosive. It does take longer to work but I think it is less damaging to the cell as well.
 
Forgot to mention that the RJ45 is similar to the T-15 shape and I have no problem using a bamboo skewer for cleaning.
