Yeah I learned from experience 😔

And I only say to use the clear stuff because it makes cleaning much easier. I’m sure it’s perfectly fine otherwise. edit: this is wrong, apparently; the red dye is in fact bad for them.

But yeah it really needs regular cleaning. It may look OK on the outside, but those holes fill up quick.

I use an app called Sweepy to help me stay on track with what needs cleaning and when it needs it, otherwise I’d totally space it.
