Vinegar is safe to use on machines made using natural rubber seals and parts constructed from ethylene-propylene, silicone, fluorocarbon, virgin Teflon, and butyl synthetic rubber seals.
Once you're removed most of the silicone use a cloth and some methylated spirits to wipe the remnants off. The methylated spirits act as a solvent in this scenario helping break down the last of the silicone and making it easier to manage and less sticky.
1) Remove old caulking (the easy way).
Removing caulk can be a time-consuming job. To make the task easier, spray any peeling caulk down with WD-40 and let it sit for 10 to 20 minutes. This will help loosen the caulk before you use a 3-in-1 removing tool.
WD-40® is very good at removing silicone sealant, but make sure you completely remove it from the surface before applying any new silicone sealant, as they can react.
Remove White Powdery Residue From Silicone
To remove the problem, soak the silicone pieces in distilled white vinegar for about 30 minutes. The vinegar will cut through the mineral deposits. Rinse the pieces well and dry with a microfiber cloth.
You can use a utility knife or putty knife, slicing through the caulk and peeling it away. For multiple layers of caulk, needle-nosed pliers might work best. There are also specialized caulk removal tools designed to tear away caulk cleanly.
