Does using a system cleaner hurt a SSD?

Does using a system cleaner that wipes files, cleanes browser cache, cleans the recycle bin, etc and writes over it (1-3 times) for secure erase hurt a SSD drive?

I know for really wiping a SSD you use the secure erase program that a manufacturer has for their SSD drive. That of course it what you do if you plan to sell it or to a clean install.

Attempting to overwrite a file with software is slightly harmful to an SSD, but more importantly it doesn't do what you wanted it to do. Hard drives always store files in the same blocks except in the unlikely event that a block gets corrupted. SSDs avoid using the same blocks twice with wear leveling. Plus part of a file might wind up in a "used" block as the SSD swaps in fresh blocks for those that have worn out their writing ability (but not their readability).

So I'd say the answers are to either use secure erase or avoid ever writing files that you might want to wipe to an SSD.

With an SSD, always use FDE (full disk encryption), if you plan on ever writing sensitive files.

Why not just create an encrypted container for the sensitive files. No reason to encrypt the whole SSD.

Because of temp files, and the paging file.

Just wire an explosive charge to the SSD.

When you hear your door being smashed in, push the big red button before the flashbangs go off and the tear gas takes you out.
