Site Title: SEITZ Cavesol 1L/5L | Tannin & Tanning Agent Stain Remover - Getwash
Meta Description: Cavesol by SEITZ Germany — specialized spotting agent for tannin & tanning agent stains: coffee, tea, wine, soft drinks, fruit juice, grass. Available 1L & 5L at Getwash.
Not all stains are created equal. While sugar or sweat stains can be handled with a water-soluble spotting agent, there's a completely different category of stains that's far more stubborn because it contains tannins and tanning agents — stains from coffee, tea, wine, soft drinks, and even grass. These stains are notoriously hard to remove because their compounds bond tightly with fabric fibers, and improper handling can turn them into permanent marks. This is exactly the problem SEITZ Germany addresses with Cavesol, a professional spotting agent specifically designed for stubborn tannin and tanning agent stains.
This article covers everything about Cavesol — what it is, how it works, the stain types it handles, correct application, and why it deserves a permanent spot on your professional laundry's spotting table.
Cavesol is a spotting fluid produced by SEITZ GmbH, a company based in Kriftel, Germany, long trusted by the international laundry and dry-cleaning industry under their tagline "The fresher company." Unlike Frankosol, which targets water-soluble stains, Cavesol is formulated specifically to handle tannin and tanning agent-based stains — a category caused by natural compounds found in beverages and plants that are known for being some of the most troublesome stains in day-to-day laundry work.
Tannin stains have a distinctive trait: their coloring molecules (such as tannins in tea and wine, or chlorophyll in grass) have a chemical structure that binds strongly to fabric fibers, especially natural fibers like cotton and linen. The longer they're left untreated, the deeper these tannins "lock in" to the fabric structure, and heat from drying or ironing can seal the stain in permanently.
Unlike water-soluble stains, which tend to remain stable and unchanged even after a few days, tannin stains are dynamic — their color continues to shift and darken due to oxidation on contact with air. This is exactly why fast treatment and using the right category of product matter so much for this type of stain, and why SEITZ developed a separate formula for it rather than folding it into a single all-purpose product.
In the professional laundry industry, stains are generally grouped into a few major categories:
Cavesol is specifically designed for the second category. Using the wrong product category — for example, trying to remove a coffee stain with a regular water-based spotting agent — often only fades the surface of the stain without truly lifting the tannin, leaving a faint mark still visible once the fabric dries.
Cavesol works by breaking the chemical bond between tannin/tannin molecules and fabric fibers. Tannins found in coffee, tea, and red wine are generally polyphenolic compounds that oxidize easily and darken over time — which is why a coffee or tea stain left overnight tends to be much harder to remove than a fresh one.
When applied to a stain, Cavesol penetrates the fibers and begins loosening the bond between the tannin and the fabric structure. This allows already-oxidized tannin to re-dissolve and lift more easily during the next wash. Just like Frankosol, Cavesol functions as a pre-treatment rather than a detergent replacement — it prepares the stain so the main wash cycle can work far more effectively.
Because tannin properties vary depending on their source (tea tannin behaves differently from grass chlorophyll, for instance), Cavesol is formulated with a concentration strong enough to handle multiple types of tannin stains at once. This product is recommended for professional users only, and testing on a hidden area of the fabric remains a mandatory step before applying it to the main area, since reactions can vary depending on fabric type and color.
Coffee and tea contain high levels of tannin — a compound that soaks into fabric fibers quickly and is known as one of the hardest stains to remove in the laundry industry, especially on light-colored fabric.
Wine is one of the most feared stains in the laundry and hospitality industry because its tannin content is highly concentrated and absorbs quickly into fabric fibers. Cavesol is specifically designed to handle this type of stain.
Dark-colored soft drinks contain tanning agents and dyes that easily leave marks if not treated promptly. Cavesol effectively dissolves this residue from fabric fibers.
Fruit juice and fresh fruit such as berries, mango, or citrus contain natural tannins that can leave strong stains, especially on white or light-colored fabric.
Colored beverages in general can leave tannin stains that soak in quickly, especially if left to dry without early treatment.
Grass contains chlorophyll, a natural green compound notoriously difficult to remove due to its unique structure and tendency to bond strongly with fabric fibers. This stain is commonly found on sports uniforms or children's clothing.
Certain perfumes contain dyes and alcohol that can leave marks on fabric, especially dark-colored or delicate materials.
Some liquid medicines or syrups contain tanning agents and coloring compounds that can leave stubborn stains. Cavesol is also effective at treating this stain type.
Identify the source of the stain and estimate its age. Fresh tannin stains are far easier to lift than ones that have been sitting for a while and have already dried in.
Apply a small amount of Cavesol to an inner seam, wait a moment, then check for any color or texture reaction before continuing to the main area.
Once confirmed safe, wet the stained area with enough Cavesol and let it soak in so the liquid can start loosening the bond between the tannin/tanning agents and the fabric fibers.
For stains that have been sitting for a while, soak the area longer and help the process along by gently dabbing with a soft brush. Avoid scrubbing too hard, as this can damage the fabric fibers.
Repeat the wetting process a few times on old coffee, tea, or wine stains for the best result before the fabric goes into the main wash cycle.
This is the most critical mistake for tannin stains. Unlike relatively stable water-soluble stains, coffee, tea, and wine stains continue to oxidize over time. The longer they're left untreated, the darker and more deeply bonded the tannin becomes to the fabric fibers, making the spotting process far harder even with the right product.
Heat from a dryer or iron can "bake in" any remaining tannin, locking it in permanently. Always inspect the fabric under bright light before drying to make sure no residue remains.
Trying to treat a coffee or wine stain with a spotting agent designed for water-soluble stains usually only fades the surface color without truly lifting the tannin from within the fibers, causing a faint mark to reappear once the fabric dries.
Dark fabric is often assumed to be "safe" from visible color change, but chemical reactions can still occur even if not immediately obvious. A hidden-area test is still mandatory on fabric of any color.
Many home-based laundries still rely on conventional methods like soaking fabric in hot water or manually scrubbing coffee or wine stains. Here's why a Cavesol-based approach is far more effective.
Hot water is often used to "fade" coffee or tea stains, but heat can actually accelerate tannin oxidation, making the stain even harder to remove. Cavesol works chemically without requiring high temperatures, avoiding this risk entirely.
Unlike soaking the entire fabric, Cavesol allows for precise treatment of just the stained area, keeping the rest of the fabric's original color intact.
Manual scrubbing often produces uneven results — sometimes the stain disappears, sometimes it just fades. With a spotting SOP built around Cavesol, results become far more predictable from one piece of linen to the next.
Fine dining restaurants or hotels with wine service frequently deal with red wine stains on white tablecloths. Applying Cavesol immediately after the incident, before the tablecloth joins the general laundry pile, significantly increases the chance of a full recovery compared to waiting for the next day's regular wash.
Café or barista uniforms are prone to daily coffee spills. Laundries serving this segment can make Cavesol a standard part of their weekly pre-treatment SOP to keep uniforms looking professional.
School sports uniforms or football club kits often get grass stains on the knees and pants. The chlorophyll in grass is a tannin stain that's difficult to remove with regular washing, making Cavesol application as a pre-treatment highly recommended before the main wash cycle.
A consistent SOP like this helps your laundry handle tannin and tannin stains more reliably, reducing the risk of complaints from institutional clients like hotels and restaurants who pay close attention to their linen quality.
For laundries already using Frankosol, a natural question comes up: when should you switch to Cavesol? Here's a simple guide to help distinguish between the two.
Use Frankosol for stains from sugar, milk, sweat, urine, honey, ice cream, and street dirt — stains that generally don't leave strong tannin but tend to be sticky or contain salt/protein.
Use Cavesol for stains that leave strong, stubborn coloring like coffee, tea, wine, soft drinks, fruit juice, and grass — stains that tend to oxidize and darken over time.
For mixed stains — such as a spilled sugary colored drink like syrup or fruit cocktail — combining both products often gives the best result: Frankosol to dissolve the sugar component, Cavesol to lift the color tannin. Having both on your spotting table ensures your team is ready to handle nearly any stain that might come up in daily operations.

Yes. The two complement each other — Frankosol for water-soluble stains, Cavesol for tannin and tannin stains — giving your spotting table more complete stain coverage.
Cavesol is generally safe, but a hidden-area test is always required first, especially for dark-colored or delicate fabric.
Because the tannins in coffee and tea oxidize over time, the longer they're left untreated, the stronger their bond to the fabric fibers and the darker the color becomes.
Yes. Chlorophyll in grass falls under the tannin stain category that Cavesol's formula is specifically designed to target.
For laundries with high tannin stain volume (e.g., serving restaurants/cafés), the 5-liter jerrycan is more cost-efficient per liter than repeatedly buying 1-liter bottles.
Cavesol can still help lift old perfume or medicament stains, but like other tannin stains, the longer they've been left, the more likely repeated application will be needed for the best result.
No. Cavesol is applied directly in its pure form to the stain as a pre-treatment step. Mixing with detergent happens separately during the main wash according to your laundry's standard procedure.
Cavesol by SEITZ is an essential complement to your professional laundry's spotting table, specifically for handling stubborn tannin and tannin stains like coffee & tea, wine, soft drinks, fruit juice & fruit, beverages, grass, perfume, and medicaments. Combined with Frankosol, your laundry business gains a complete solution for nearly every type of stain it might encounter on a daily basis.
