Kotton Fabric (or as some say Cotton Fabric) in the game Probably Stolen is a specialized filtering material that can be useful for chemistry and water purification. However, it doesn't behave like an ordinary Water Filter, which can make it seem completely useless when you're first experimenting with it.

How to Get Kotton Fabric in Probably Stolen
To produce Kotton Fabric, grow Kotton in a Hydroponic System equipped with the Kotton Loom module. The module allows the farming system to produce fabric rather than the usual Kotton fiber.
- Obtain Kotton seeds and a Hydroponic System.
- Install the Kotton Loom module in the farming system.
- Set up the Hydroponic System with the power, water, and growing supplies it requires.
- Plant the Kotton seeds and allow them to grow.
- Collect the Kotton Fabric produced through the loom-equipped system.
Kotton normally takes approximately four nights to grow, although growth conditions and upgrades can affect production.
The important distinction is that growing Kotton alone doesn't necessarily give you finished fabric. The Kotton Loom module is what allows you to obtain the processed material through hydroponic farming.
The available information doesn't establish a specific guaranteed vendor or unlock requirement for the Kotton Loom, so check the farming equipment and module stock available during your playthrough.
How to Use Kotton Fabric in Probably Stolen
Kotton Fabric works as a specialized filtration material. Place it in a Water Pitcher and pour liquid containing the appropriate physical material through it.
- Open a Water Pitcher.
- Install Kotton Fabric in the pitcher's filter slot.
- Pour the liquid you want to process through the pitcher.
- Collect the filtered liquid in another container.
- Check whether the targeted contamination has been reduced.
Unlike an ordinary Water Filter, Kotton Fabric is intended for specific contaminants rather than general water cleaning.
Its main use is separating material such as plant matter and larger physical deposits from liquids, particularly those created during processing or chemistry.
What Does Kotton Fabric Actually Remove?
Kotton Fabric is useful for solid debris and plant-based material suspended in liquid. This includes some contamination introduced by blending ingredients.
It doesn't serve as a universal solution for microbes, dissolved chemicals, or heavy metals.
This distinction matters because a water sample can be highly contaminated without containing anything the fabric is designed to catch.
Why Isn't Kotton Fabric Filtering Water?
If you've placed Kotton Fabric inside a Water Pitcher and nothing happens, the likely explanation is that the water doesn't contain the type of contamination it removes.
For example, ordinary Gutterflow water isn't improved by Kotton Fabric because its contaminants aren't the specific suspended materials the fabric targets.
That can also explain why the fabric doesn't lose durability during treatment. If the relevant contaminants aren't present, there may be nothing for it to filter.
Why Does a Normal Water Filter Work Instead?
A standard Water Filter handles a broader set of common physical and organic impurities. Kotton Fabric has a narrower purpose.
If your water contains contamination that a normal filter can remove but no solid debris or plant matter, switching to Kotton Fabric won't necessarily provide any improvement.
Before replacing your filters, determine what is actually preventing the water from reaching a higher purity grade.
An AquaScan can identify different contamination types, making it easier to decide whether Kotton Fabric is appropriate.
For regular water trading, our Probably Stolen Water Purification Guide explains how to handle the other impurities that Kotton Fabric cannot remove.
How Kotton Fabric Works in Chemistry
Kotton Fabric becomes more useful when working with blended mixtures rather than ordinary drinking water.
In chemistry, processing ingredients can leave physical material suspended in the resulting liquid. Filtering that material is different from removing microbes or improving the liquid's chemical purity.
Filtering Blended Ingredients
After using a Blender and Heating Plate to process ingredients, you may have a liquid containing larger particles that need to be separated before further processing.
Kotton Fabric can be installed in a Water Pitcher to strain those deposits from the mixture.
The exact amount removed depends on the contamination present and the condition of your filtering equipment. It shouldn't be treated as a guaranteed way to make every chemical mixture pure.
The practical advantage is that you can remove unwanted physical material without expecting the fabric to handle contaminants outside its intended role.
Can Kotton Fabric Help Produce Pure Water?
Yes, under specific conditions.
Players have experimented with mixtures containing organic material and solid particles, including liquid produced from rat waste. Because these mixtures contain a narrower range of contaminants than ordinary dirty water, the individual impurities can be treated with different tools.
Kotton Fabric can remove the relevant physical material, while UV treatment, purification equipment, and other filters deal with the remaining contamination.
Some players have reported reaching extremely high purity through combinations of these methods, but Kotton Fabric alone isn't responsible for the result.
This is a specialized application rather than the normal approach to producing drinking water for sale.
Kotton Fabric vs. Water Filter: Which Should You Use?
The best option depends on what you're filtering. Although both can be installed in a Water Pitcher, they don't have identical effects.
| Situation | Better Choice |
|---|---|
| Ordinary water trading | Standard Water Filter |
| Plant matter from blended ingredients | Kotton Fabric |
| Large physical deposits in a mixture | Kotton Fabric |
| Microbial contamination | UV Lamp or suitable purification treatment |
| Chemical or heavy metal contamination | Appropriate purification equipment |
I'd keep Kotton Fabric available if you're regularly processing blended materials or experimenting with complex mixtures. For ordinary bottles of contaminated water, a standard Water Filter is generally the more useful starting point.
Ultimately, Kotton Fabric isn't a defective version of the Water Filter. It's a specialized tool designed for a different kind of contamination, and understanding that difference is what makes it useful.
