Oh dear! Not that ones!
Any tips for use would be appreciated, I’m using water soluble ChipQuik solder and I assume I’ll need to use distilled water in the cleaner.
Never use a flammable liquid (iPA, acetone, etc) as the fluid will get hot (~40-50°C after half an hour without external heating), this can be a serious fire hazard.
There is a good stuff called trans-dichloroethelene (DCE), which is a non-flammable (when mixed with fluorinated solvents to form azeotropes), and not very toxic (benign enough to be approved for use as flux remover in most jurisdictions) flux remover.
Mix the azeotrope with some alcohol, and ethyl acetate and limonene (both are not flammable in low concentration dissolved in DCE), you get a perfect flux remover.
There are quite a few such mentioned products available on the market. I use Mechanic N880, which seems to be fairly available in China, then I mix a tiny bit of limonene to it to enhance its capability to remove adhesives and use the mixture as a "one fits all" remover product. Basically it's my version of "cum gutter".

You don't have to if you just want to use it for rough cleaning (the one in our lab only gets tap water plus the occasional shot of citric acid and it's still in good shape after years of daily use), but if you don't want to rinse your boards after cleaning them i'd recommend using DI water (also, it's a good idea to change the water after every 1-2 uses, DI water from an ion exchanger is cheap).

Cheers, DI is cheap here, iirc 12 litres cost me about $20.

Your local Woolies might have the Moore's pure water, 5L for just under 5 dollarydoos. It's so easily available I use it generously when cleaning PCB's.
It holds the paper down electronically, I have no idea how. Electrostatic? It's quite a firm grip!

Picked up a mint condition Bruel and Kjaer XY plotter at a hamfest for 10$!
Brüel and Kjær was an extremely HQ test equipment manufacturer, particularly acoustics and vibration analysis.
Roll graph plotters are always a gamble because of the scarcity of paper rolls. This one takes regular A4!
