How do you, using a trigger (or whatever entity,) to erase paint that it ALREADY painted on the walls? I have a bit in my map where a bunch of sprinklers turn on to wash away the floor, I've got the particles and sounds and everything but it seems trigger portal cleansers (EDIT: I meant to say trigger_paint_cleanser) only effect the paint blobs, not the walls.

I know this can be done, cause right at the finale of the main story campaign, in Wheatley's chamber, the sprinklers turn on and the paint on the floor does the cool wash away dissolve. So how might I go about doing that?

How big is the area? I got this to work mildy well with water sprayers around the effected area that is triggered for a split second through I/O when you want it cleaned. I could imagine this wouldn't work to well with a larger area, or maybe it would IDK

Noooooo. Never use sprayers to pre-paint things. It can work, but with larger areas its hard to control, and may multiple sprayers are needed.

To apply paint on a surface or an area, I use PAINT_SPHERE. You can set the paint radius and paint type, and with a logic_auto (onmapspawn) you can tell it to "Paint".
If you want to erase something, just set the radius big, the paint type to "Erase"...
when I use it to paint, I usually tell it to Paint several times (3 tims, waiting 0.1 sec between).
BTW its a good idea to use this paint_sphere with 0.5 alpha and 64 radius under paint droppers so the player can see some paint drop on the floor and knows what type of paint that dropper drops.

Remember that everything you do is utilizing Valve-designed test elements. Also remember that the majority of people playing your map will be expecting a challenge similar to what they've already experienced, rather than something completely different from the Valve-made levels, and the introduction of too much "outside-the-box" thinking as part of a solution may intimidate and drive people away unnecessarily.

Valve maps were made by different mappers, and even the official ones use weird and overcomplicated methods for stuffs. Or maybe the paint_sphere was added later in development, but definetely the best way to place paint in an area, and the radius can be huuuuge. Easier than setting up sprayers with their properties (and the engine must launch blobs for all of them)...

This is huge. I imagine a lot of the maps were fixed up (i.e. jury rigged) from earlier maps, not scratched and rebuilt as the game evolved.

My apologies, I deleted the post before I saw you write this.

Ah well, the quote lives on I suppose.
