Ghastly business!

Use caulk remover, sold in tubes that look just like those for bathtub
caulk. *DAP makes it, and it's green goo. *Lacquer thinner also works,

you do a really good job of removing the mildew, such as with bleach

mildewcide.

OH,THANK YOU THANK YOU for all suggestions. *I *should have realized
there might be such a product. *I do have sort of a "heat gun" --

any.
Other suggestions?

Also, how effective is the mildewcide in bathtub caulk (specifically
silicone, which has been recommended by most (all?).
IOW, do I need to add anything?

TIA


LOL... If you are using a soldering iron to try and de-caulk a tub,
no wonder you are having troubles...

You need a HEAT GUN, which is basically an industrial strength
hair dryer, which will provide more heat over a broader area than
what a soldering iron will be able to put out...

You heat the old caulking and it will come out much easier with
your razor scraper and other tools...
