Is this washer a vertical slot unit made of transparent plastic ("perspex" I'm tempted to call it, but it could be something else. Is acrylic the same thing?)

I have found that some algae grow in it but is easily removed. Once the surface is abraded, everything will stick to it, not that there should be much in a print washer.
To prevent algae growth, I use a little liquid pool chlorine in the washer when I leave it full.
As Patrick has said, tailor the cleaning to what needs cleaning. Let us know what that is.
