The chemical am using (suggested by an expert) is very good (giving me in some drives 10-20% speed improvement)
but if reaching the 55 degrees will be really bad/harmful.

For some time i was thinking about improving Reading Performance of drives with Weak heads (when you run out of donors)
and i came up with some results (not finished yet) still working on it with good & improving results (but not good enough to consider it as a final result)
It is always about the material being used and the % of the mixed liquids (which am trying to figure out here)
I did some tests and here is a sample recorded video of it where you will notice the Diff. in Temp. inside & outside the container.

Am ready to share my experience with anyone who worked on this research and made some progress (hope better than what i did)
I think we will get to something @ the end.
Thank you

Well,
i do not need to explain the folks out here that under 1 month of time a conclusion cannot be formed ,This guy posted here -> https://www.data-medics.com/forum/post10381.html#p10381 and in under 1 month he is giving a opinion .The only other liquid he is used in 99% isopropyl .In this thread -> https://www.data-medics.com/forum/clean ... t1271.html many people posted negative about this liquid he is saying is good .The Thing Everyone Needs To Know is That Isopropyl if opened can suck moisture like a pig and then reduces that 99% claim .You should know how to handle the moisture situation .The Recoding is Done At The Third Layer if counted from the top of platter surface

Oh, yes, definitely, that could be the case if using dangerous chemicals.

Some other solvents can be used but their are either toxic, like ccl4 or hard to store/use like iso 99.99% iso is also not very good for the job because it can react (I think) with some lubricants.
2. Cleaning the whole platter w/o re-lubrication is asking for MD, and proper lubricant deposition can only be done using PFPE solvents, not to mention that the lubricant itself is almost impossible to find.
3. Most common dirt on the heads is either plastic from the ramp or delaminating lubricant. I'm not taking into consideration physical damage of a platter.
Plastic contamination has rather large particles and can be removed w/o ultrasonic
Removing delaminating lubricant from the heads is pointless w/o first removing it from the platter
And most importantly if you do all the cleaning that means you have too much of a free time
