I was considering getting Regul Save Cleaner, but I've heard there were some problems with it.

Do you know if there are other save cleaners out there, something that wouldn't hurt the game?

I use Regul Save Cleaner with no problems.

There is also an older one by Kuree, which I have used for years before. This one, I had some issues with occasionally. The saved game wouldn't load or took forever sometimes. I never found out why

Another option is doing it manually. I did this for a long time without issues.

I have the older version of Kuree save cleaner and this one works well. My game has never had an issue with using this version.

I also use regul's save cleaner, it's great. Just be careful about what options to clean you set - there is an option that deletes in-game pictures like wishing cards, photos your sims hung up, etc, and it's a shame to lose those
