Preparing Your Raw Fleece for the Wash Tub

Before any water is drawn, a raw fleece must undergo thorough skirting to remove heavily soiled edges, second cuts, and large pieces of vegetable matter. Lay the fleece out flat on a mesh surface or clean grass, tips facing up, and ruthlessly pull away the dung-stained locks from the breech and belly. Skipping this step means washing unnecessary filth, which wastes expensive detergent and pollutes the wash water prematurely.

Once the heavy debris is discarded, gently shake the fleece in sections to release loose dirt, dust, and tiny seeds trapped within the locks. Divide the fleece into manageable portions, typically half-pound to one-pound bundles, which fit easily into washing bags. Organizing the wool into distinct batches at this stage prevents tangling and ensures even water penetration during the wash cycle.

Wash Basin – Behrens 17-Gallon Galvanized Tub

Washing raw fleece requires a sturdy, heat-resistant vessel that can hold large volumes of water without flexing or cooling down too quickly. Standard plastic utility tubs often warp under the weight of near-boiling water, leading to dangerous spills and rapid heat loss. A dedicated wash basin must hold enough water to submerge the wool fully, allowing the dirt and grease to drop to the bottom away from the fibers.

The Behrens 17-Gallon Galvanized Tub is the gold standard for backyard fiber processing due to its heavy-duty steel construction and rust-resistant zinc coating. This tub handles near-boiling water effortlessly, maintaining the high temperatures needed to melt stubborn sheep lanolin. Its offset bottom keeps the metal off the cold ground, while the drop-handle design makes carrying heavy loads manageable.

• Capacity: 17 gallons (ideal for washing 2 to 3 pounds of raw wool per batch)
• Material: Hot-dipped galvanized steel, rustproof and rodent-proof
• Dimensions: 24.25" x 24.25" x 11"

Because steel conducts heat rapidly, using this tub on cold concrete will draft heat away quickly; placing a wooden board or foam pad underneath helps preserve water temperature.

This tub is perfect for the homestead fiber processor who values durability and needs to wash multiple fleeces a year. It is not suitable for indoor apartment use where space is tight and lifting a heavy metal basin is impractical.

Wool Scour – Unicorn Power Scour Detergent

Raw wool is coated in lanolin, a sticky natural wax that binds dirt, dung, and grit to the fibers. Standard household detergents or dish soaps lack the chemical strength to break down this heavy grease, often leaving a sticky residue that ruins spinning equipment. A specialized wool scour chemically strips the wax at high temperatures without damaging the delicate protein structure of the wool fibers.

Unicorn Power Scour Detergent stands out because it targets stubborn grease at lower temperatures than traditional scouring agents, though it performs best in hot water. Its formula is highly concentrated, meaning a small bottle goes a long way, and it rinses out incredibly clean without leaving artificial fragrances or sticky films behind. It effectively lifts deep-seated dirt while preserving the natural bounce and luster of the fiber.

• Recommended Temperature: 120°F to 140°F for optimal grease removal
• Concentration: Highly concentrated (use roughly 1 to 2 tablespoons per pound of dry wool)
• Eco-Friendly: Biodegradable and septic-safe

Overusing this scour can strip the wool too bare, leaving it feeling harsh and brittle, so precise measurement is key.

This product is essential for anyone processing fine, greasy fleeces like Merino, Shetland, or Romney. It is overkill for low-grease fibers like alpaca or mohair, where a milder fiber wash would suffice.

Mesh Bag – Poleacre Heavy Duty Laundry Bag

Submerging loose wool directly into a wash tub is a recipe for disaster, as the fibers will float apart, tangle, and felt during handling. Mesh bags keep the individual locks organized and contained, allowing water and soap to flow through while preventing any agitation. They make transferring wet, heavy wool between the wash and rinse tubs clean, fast, and stress-free.

The Poleacre Heavy Duty Laundry Bag features a robust, fine-mesh weave that prevents tiny wool tips from poking through and tangling with other bags. The heavy-duty zipper is equipped with a protective elastic cover, ensuring it won’t snag delicate fibers or open mid-wash. Its spacious design allows the wool to expand slightly, ensuring thorough cleaning without compressing the fibers into a dense lump.

• Size: 24" x 24" (holds up to 1.5 pounds of raw fleece comfortably)
• Material: High-density polyester mesh with reinforced seams
• Closure: Rust-proof zipper with elastic guard

Avoid stuffing the bags to maximum capacity; wool needs room to move slightly so water can wash away the dissolved grease and dirt.

This bag is ideal for shepherds and fiber artists who wash medium-to-fine fleeces in structured batches. It is less suited for those washing giant, longwool locks like Wensleydale, which require flat-washing techniques to preserve lock structure.

Thermometer – Taylor Precision Dial Thermometer

Temperature control is the single most critical factor when washing raw wool. If the water is too cool (below 120°F), the liquefied lanolin will re-solidify onto the wool, creating a gummy mess that is nearly impossible to remove. Conversely, extreme heat combined with sudden temperature drops will shock the fibers, causing instant, irreversible felting.

The Taylor Precision Dial Thermometer provides instant, highly accurate temperature readings without the fragility of glass designs. Its long stainless steel stem allows you to measure the temperature deep within the wash tub without burning your fingers. The large, easy-to-read dial features clear markings, making it simple to monitor the cooling rate of your wash water.

• Temperature Range: 0°F to 220°F
• Stem Length: 8 inches (perfect for deep wash tubs)
• Calibration: Easily recalibrated using the nut under the dial face

Keep the dial face out of direct steam for prolonged periods to prevent condensation from clouding the display.

This tool is a must-have for any home fiber processor who wants to eliminate the guesswork of water temperature. It is not necessary for those processing pre-scoured wool or non-greasy exotic fibers that do not require hot-water washing.

Rubber Gloves – Showa 377 Nitrile Foam Gloves

Washing raw fleece requires working with very hot water, strong detergents, and dirty, bacteria-laden animal grease. Bare hands will quickly become scalded, dried out, or exposed to zoonotic pathogens sometimes present in raw fleece. Heavy-duty gloves protect your skin from high temperatures while maintaining the dexterity needed to handle delicate wool locks.

The Showa 377 Nitrile Foam Gloves offer an exceptional balance of liquid-proof protection and tactile grip. Unlike cheap dish gloves that tear easily and slip when wet, these gloves feature a fully coated nitrile base with a foam nitrile palm finish for superior grip in soapy water. The knit wrist sleeve keeps the gloves securely in place and prevents hot water from splashing down inside.

• Coating: Double-dipped nitrile with foam grip
• Liner: Seamless 13-gauge polyester/nylon knit
• Length: Extended cuff for wrist protection

These gloves run slightly small, so purchasing one size up is recommended to ensure they are easy to pull off when hands get warm.

These gloves are perfect for backyard processors handling multiple hot rinses and greasy fleeces. They are not ideal for those who prefer loose-fitting, elbow-length chemical gloves for deep-vat dipping.

How to Avoid Felting Your Wool During Washing

Felting occurs when wool fibers are subjected to the combination of heat, moisture, and agitation, causing the microscopic scales on the hair shafts to lock together permanently. Once a fleece is felted, it becomes a solid sheet of felt that cannot be spun, carded, or combed. The golden rule of wool washing is never agitate the wool while it is wet and hot; simply let it soak.

When transferring the wool between the wash tub and rinse tubs, always ensure the water temperatures match within 10 degrees. Plunging hot wool into cold water shocks the fibers, causing them to contract rapidly and felt instantly. Gently press the water out of the mesh bags rather than wringing or twisting them, as twisting creates friction that ruins the fiber structure.

Spin Dryer – Laundry Alternative Nina Soft Spin

Wet wool holds an immense amount of water, which can take days to air dry, risking mold, mildew, and fiber rot. Traditional washing machine spin cycles can be too aggressive, plastering the wool against the drum and causing felting. A dedicated gravity-drain spin dryer removes up to 90% of the water in just a few minutes using centrifugal force without agitating the fibers.

The Laundry Alternative Nina Soft Spin is a compact, highly efficient countertop spin dryer that is incredibly gentle on delicate fibers. It spins at a rapid 1800 RPM, forcing water out of the wool and draining it through a front spout into a bucket. Because the drum does not agitate or blow hot air, the wool remains perfectly safe from felting during the extraction process.

• Spin Speed: 1800 RPM
• Capacity: 12 lbs dry weight (perfect for processing a whole fleece in sections)
• Power: 110V standard outlet, highly energy-efficient

The unit must be loaded evenly to prevent it from wobbling or walking across the floor during operation.

This spin dryer is a game-changer for homesteaders processing multiple fleeces a year who want to slash drying times from days to hours. It is not necessary for occasional hobbyists washing tiny, ounce-sized sample locks.

Drying Rack – Homz Hanging Sweater Dryer

Once the bulk of the water is spun out, the wool must be laid flat to finish drying. Hanging wet wool from a clothesline stretches and distorts the locks, while piling it deep on a solid surface traps moisture and causes sour odors. A breathable, flat drying rack allows maximum airflow from both above and below, speeding up the final drying stage.

The Homz Hanging Sweater Dryer is a multi-tier, space-saving solution that hangs easily from a ceiling hook, closet rod, or outdoor clothesline. Made from durable, breathable mesh, it keeps the wool flat and separated to maximize air circulation. Its tiered design allows you to dry different sections of a fleece simultaneously without them touching or mixing.

• Design: 3-tier hanging rack with 360-degree swivel hook
• Material: Rust-proof plastic frame with heavy-duty mesh
• Storage: Folds completely flat when not in use

Ensure the hanging location has good air circulation, as stagnant indoor air will significantly slow down the drying process.

This rack is perfect for indoor processors or those with limited porch space who need to dry wool efficiently. It is not sturdy enough to hold soaking wet wool that has not been spun dry first.

Skirting Screen – Outwell Foldable Drying Net

Outdoor drying is highly efficient, but wind, insects, and curious farm animals can ruin a clean fleece in minutes. A secure, enclosed drying screen protects the washed wool from blowing away while keeping flies, wasps, and birds from nesting in the clean fiber. It provides a controlled microenvironment that utilizes natural breezes without exposing the wool to outdoor contaminants.

The Outwell Foldable Drying Net features fully zippered mesh compartments that keep your clean wool entirely enclosed and protected. The sturdy internal wire frame keeps the shelves taut, preventing the wool from sagging into clumps. Its collapsible design means it packs down into a tiny carry bag, making it easy to store in the barn or utility closet when the washing season ends.

• Tiers: 4 spacious compartments
• Closure: Heavy-duty zippers on each level
• Portability: Folds down into a flat, circular disc

Hang this net in a shaded, breezy area; direct, intense sunlight can bake the wool and make the fibers brittle.

This net is excellent for homesteaders who dry their wool outdoors on porches, in barns, or under trees. It is not needed if you dry your wool exclusively in a climate-controlled indoor space.

Crucial Tips for Air Drying Your Clean Fleece

Air drying is the final step in the washing process, but it requires patience and the right environmental conditions. Always dry your wool in the shade or indoors with a fan running to facilitate airflow. Direct sunlight can yellow white wool, dry out the natural moisture within the fiber protein, and make the locks harsh and difficult to spin.

Spread the wool out in a thin, single layer on your drying racks rather than leaving it in thick clumps. Turn the locks over once or twice during the drying process to ensure the bottom layers get equal exposure to the air. Never rush the process by using a hair dryer or placing the wool directly on a radiator, as forced heat will ruin the fiber’s elasticity.

Storing Your Washed Wool to Prevent Pests

Clean, dry wool is a magnet for clothes moths, carpet beetles, and rodents looking for nesting material. Before storing your hard work, ensure the wool is 100% dry; even a tiny amount of residual moisture will cause mold and attract pests. Store the clean wool in breathable, zippered cotton bags or heavy-duty plastic bins with tight-fitting lids.

To deter pests naturally, add sachets of lavender, cedar chips, or cloves to your storage containers. Avoid using traditional mothballs, as their chemical scent is incredibly difficult to wash out of the finished yarn. Check on your stored fleeces every few months, giving them a quick shake and fresh herbal sachets to ensure they remain pristine for future spinning.

Washing raw fleece at home is a deeply satisfying bridge between animal husbandry and fiber artistry. With these eight essential tools and techniques, you can confidently transform greasy, field-worn wool into a clean, beautiful canvas ready for your next creative project.
