Seal & Grout Mold Stain Remover
A clinging gel for mold and mildew stains in the seams, seals, and corners that need a closer clean.
Where to buy How to use
Dark staining around a shower seam or appliance seal can make an otherwise cared-for space feel unfinished. TOSS Seal & Grout Mold Stain Remover brings a focused approach to these narrow problem areas: a precision nozzle places the gel where it is needed, and the clinging formula stays on the treated spot while it works. Use it for localized mold and mildew stain removal, then wipe away residue and rinse thoroughly. It is a detail-cleaning treatment, not a machine cleaning cycle or a repair for damaged seals.

A gel lets you apply cleaner to the specific area that needs attention. Thoughtful care means treating compatible surfaces, using protective equipment, and managing unused cleaner responsibly alongside the ventilation and maintenance your home needs.
FOUR REASONS TO KNOW IT
A gel that stays in place while it works.
Place the gel along narrow seams and corners.
Target local stains around compatible grout and seals.
After treatment, wipe away gel residue and rinse thoroughly.
WHERE TO USE IT
Made for localized mold and mildew stain treatment around the seams and seals shown below. A precision application belongs on the affected spot—not across the whole appliance or room.
Target localized staining along compatible tiled shower seams, corners, and caulk.
Keep treatment focused: Keep away from natural stone, metal fittings, painted finishes, and fabrics unless their compatibility is established.
Treat localized stains along the compatible sealed seam where the toilet base meets the floor.
Keep treatment focused: This is seam treatment, not toilet-bowl cleaning. Avoid metal fixtures and unverified floor finishes.
Apply only to a small affected area of a compatible rubber door seal or its folds.
Keep treatment focused: Do not add gel to the drum or detergent drawer, or run a machine cycle with it. Remove all residue and rinse thoroughly.
Use for localized staining on a compatible door seal, keeping the treatment confined to that seal.
Keep treatment focused: Keep away from dishes, utensils, racks, and detergent compartments. Do not run a dishwasher cycle with the gel.
Target a small stained fold on a compatible refrigerator door seal.
Keep treatment focused: Move food away from the work area. Keep gel off shelves and food-contact surfaces; remove all residue and rinse the seal thoroughly.
Apply a small dab to an inconspicuous area. Wait 10 minutes, then wipe and rinse thoroughly.
Check before treating: Look for discoloration or surface changes. Stop if the test area changes; a short test does not guarantee compatibility with a longer treatment.
These are intended application areas shown in the supplied packaging, not a guarantee for every surface or seal material. Apply a small amount to a hidden area, wait 10 minutes, then wipe, rinse, and check for discoloration or damage before treating a larger area. Keep gel away from fabrics and unverified finishes. Wear chemical-resistant gloves and eye protection, ventilate the space, and never mix with another cleaner. Damaged caulk or seals need repair; this gel treats surface stains.
A little focus where everyday moisture leaves its mark. Treat the affected seam, give the gel time to work, then wipe and rinse.
Meet your new routineHOW TO USE
Patch-test for 10 minutes, prepare safely, and apply precisely. Leave the gel for at least 3–5 hours; tougher stains need longer contact. Then wipe and rinse thoroughly. Keep children and pets away from the treated area.
Open ventilation and wear chemical-resistant gloves and eye protection. Shake well. Apply a small amount to a hidden area, wait 10 minutes, then wipe, rinse, and check for discoloration or damage before treating a larger area. Move fabrics away and keep other cleaners separate.
Check surface compatibility before cleaning.
Use the precision nozzle to apply gel evenly over the affected seam or corner. Keep treatment localized, avoid nearby fabrics and unverified finishes, and keep your protective gloves on.
A focused application for a small area.
Leave the gel in place for at least 3–5 hours. Tougher stains need longer contact time. Keep the space ventilated and prevent children and pets from touching the treated area.
At least 3–5 hours; longer for tougher stains.
Wipe the treated area with a damp cloth or sponge, then rinse thoroughly with water. Remove remaining gel residue before returning the surface to normal use.
Wipe residue away. Rinse thoroughly.USE & STORAGE
DANGER: Causes skin irritation and serious eye damage. May cause respiratory irritation. Very toxic to aquatic life.
Avoid contact with eyes and skin. Keep the cleaner separate from other cleaning products and wash your hands after handling.
Never mix with acids, ammonia or other cleaning products: toxic gases can be released. Use adequate ventilation, chemical-resistant gloves and eye protection. Store locked up, tightly closed, away from heat and sunlight; protect from freezing.
Eyes: Rinse cautiously with water for at least 15 minutes. Remove contact lenses if present and easy to do; continue rinsing and seek immediate medical attention.
Skin: Wash thoroughly with soap and water. Remove contaminated clothing and wash before reuse. Seek medical advice if irritation occurs.
Inhaled: Move to fresh air and keep comfortable for breathing. Seek medical attention if symptoms occur.
Swallowed: Rinse mouth. Do not induce vomiting. If conscious, give small amounts of water and seek immediate medical attention.
Good to know
What it targets. Where it fits. A little care for everyday life.
Damp folds and seals can hide surface staining. Look closely during your routine; damaged rubber or caulk needs repair.
The everyday need
Place the clinging gel precisely along a compatible seam. Treat the affected spot, then remove residue and rinse thoroughly.
The product’s role
After the approved removal and rinse routine, address persistent moisture. Everyday ventilation belongs alongside your regular cleaning habits.
The next momentThis product is described as a mold and mildew stain remover. Address leaks, dampness and damaged seals separately; a stain treatment does not repair them.
Use on compatible hard, non-porous surfaces only. Apply a small amount to a hidden area, wait 10 minutes, then wipe, rinse, and check for discoloration or damage before treating a larger area. Avoid fabrics and unverified colored finishes.
Use ventilation, chemical-resistant gloves, and eye protection. Never mix with acids, ammonia, or another cleaner. Wipe and rinse the treated area thoroughly.

GOOD TO KNOW
A clinging gel for mold and mildew stains in the seams, seals, and corners that need a closer clean.
The gel format is intended for targeted application to narrow seams, grout, and seals. Surface compatibility still matters before applying any cleaner.
No. Cleaning does not repair damaged grout or silicone seals. Areas that remain damaged after cleaning may need repair or replacement.
Leave the gel for at least 3–5 hours. Tougher stains need longer contact time. After treatment, wipe away residue and rinse the surface thoroughly. Keep the area ventilated and inaccessible to children and pets.
This is a localized stain treatment for compatible seams and seals, not a product for running a machine cleaning cycle. Keep gel away from food, dishes, and food-contact areas; test a hidden area before treating a seal.
