I just received a wireless relay that I purchased for a project I'm working on. The package arrived today and when I took the cover off I saw the sticker shown in the photo. What does it mean?

Use cold water only, you don't want that to shrink.

Maybe I should shower and then remove the label.

I don't know, I've never washed my seals. I mean, what's the point? They just jump right back into the ocean

[h=1]ove After Washing” on Piezo Buzzer[/h]
[TD="class: votecell"] [/TD]
[TD="class: postcell"] Maybe this is a stupid question, but here goes: I just got a piezo buzzer and on the top there is a sticker that says "Remove After Washing".
My question is why would I ever want to wash an electronic part? I have no idea. Is there some manufacturing step where this makes sense?

Many processes use "no-clean" flux today and you can remove the sticker after manufacture. Others use water soluble flux and wash the finished assembled boards in what are basically dish washers.
You can leave it on for a quieter buzzer - and a different frequency. Or remove it for a much louder buzzer plus get the tones intended in the software. (Move your finger around partly covering the hole while a buzzer is running and you will see the many frequency shifts caused by changing the acoustics). A lot of Chinese manufacturers leave them on, maybe not knowing what it says.
They also keep out dust and critters. But for that I would use something more permanent.

Rick, thanks, that makes sense. I'm going to leave the seal on to "quite" the sound.

I'm betting on don't care.
Pulling the sticker means adding an extra process step the manufacturer would have to pay for. It may be a small, almost trivial, process but it's a process none the less. The reason products have become so cheap is because manufactures have become really adept at removing expenditures of time/money/effort.
Especially if the production line is automated and making multiple products, it will be configured around processes common to all products. An oddball like peeling a sticker means adding a manual process or a specialty machine, costs they'd rather avoid.
