How to Remove Heat Sink Paste from LED Surface

Asking for a friend -

I got heat sink paste - the white kind - on the surface/dome of an LED.

What’s the best way to get it off?

Isopropanol / isopropylalcohol is one of the best solvents to clean such things

I find ordinary disposable alcohol lens wipes work well for cleaning LED domes. The same kind used for cleaning ipad screens and glasses. If you need a bit more pressure to get the corners of the dome, just use a q-tip on top of the wipe.

Alrighty I’ll give it a shot -

The use of alcohol wipes is very effective. You’re right. When working with electronics, that’s usually good enough.

yep, a paste comes off with alcohol, but dry adhesive will not, that you’ll have to physically remove,

Be fast. The white thermal compound contains silicone oil, which dissolves a silicone LED dome over time. At least it makes it foggy and wrinkly very quickly.
