Anyone removed old sealant from around their double glazing and put in fresh sealant? Any tips?

Also what’s the best way to remove sealant, Stanley blade and acetone?

It's a job that I hate.

I wouldn't trust multisolve, as you will never be able to completely remove all of the old sealant. I don't want partly softened leftovers compromising the job.
I think if the sealant s mostly good, but has a couple of small splits, cut out the small sections and renew.
If its larger splits, cut off everything as far as possible.

One sharp glazing knife /chisel for neatly cutting the sealant off the window. Sharpen with wet and dry paper down to 800 grit or more.

Another for hacking away at the wall. Keep restoring the edge with 180 grit.

Use a brush and cloth to rub away any loose leftovers
