01 The short answer
To get mildew out of suede, work in this order: (1) assess contamination and moisture; (2) professional assessment. Once dry, brush with a suede brush in one direction and use a suede eraser on any shadow.
Consult a professional experienced with this material. The difficulty rating does not establish that a home method will work.
02 Never do this
- The dryer before it is gone. Dryer heat locks in whatever is left. Air-dry and check first.
- Soaking it with water. Suede dries to a darker ring wherever it was wet.
- Mixing bleach with other cleaners. Bleach with vinegar, ammonia or acidic cleaners releases toxic gas.
03 Before you start
- Use white cloths or paper towels only: coloured ones can transfer their own dye into suede.
- Start with manufacturer-approved dry care. Do not assume a water, vinegar or alcohol treatment is suitable for the hide or dye.
- Pretest every permitted treatment on an inconspicuous area, including trims, and let it dry. Stop for colour transfer, lightening, rings, stiffness or distortion. A successful spot test does not guarantee the whole item is safe.
04 The method
Assess contamination and moisture
Fix the moisture source and keep other people away from the affected material. Follow public-health mould-cleanup guidance, including suitable gloves, eye protection and respiratory protection. Do not disturb growth with an ordinary vacuum or dry-brush it indoors. Large areas, vulnerable occupants or contaminated padding need professional advice.
Why it works: Mould cleanup requires removal and moisture control, not simply lightening the visible stain.
5 min hands-on
Professional assessment
Do not soak, bleach or repeatedly treat mouldy upholstery, mattresses, leather or delicate fabric at home. Contaminated porous materials may need specialist cleaning or disposal; obtain advice before disturbing them.
Why it works: Growth can extend below the visible surface and may be impossible to remove completely from porous material.
Brush the nap
Once dry, brush with a suede brush in one direction and use a suede eraser on any shadow.
Why it works: Brushing lifts the nap and blends the cleaned area in.

05 Dried, set, or back again?
- On suede, an old mark responds to repeated brushing and the suede eraser over several days; liquids will not help a set stain.
Assess the mark only once the item has dried according to its care instructions. If it remains, do not keep repeating or strengthening treatment; obtain advice for the exact material and product.
06 What mildew is made of
- Living mould
- Pigment particles
Mildew can involve fungal growth and staining. Correct the moisture problem, remove contamination and dry the material; killing mould alone does not remove it, and an oxidiser is not always needed or suitable. Porous materials may need professional assessment or disposal.
Mildew can contain pigment particles that do not dissolve readily in water. Many must be lifted with an appropriate cleaner rather than relying on bleach. Avoid grinding particles into the material; pigment chemistry and product formulas vary.
- Mildew is mould growing on the fabric itself. The black or grey dots are living fungal growth and its pigment, and the fibre underneath may already be weakened.
- Brush spores off outdoors first; shaking mildewed fabric indoors spreads them.
07 The material: suede and nubuck
Suede should not get wet at all if you can help it: work with solvents, powders and brushes.
No rubbing at all; every step is a press-and-lift.
No soaking, so each treatment is applied, given a few minutes, and blotted away.
- Suede is the brushed inner side of a hide, with no protective topcoat, so liquids soak straight in.
- A pencil eraser or suede eraser lifts surface dirt by friction without any liquid at all.
The suede and nubuck file rates every common cleaner for it.
08 Next time
Never leave damp laundry or towels in a pile or in the machine, dry everything fully before storing, and ventilate bathrooms.
09 Questions
Can I use hot water on mildew on suede?
Keep it cool: suede itself does not tolerate water above about 30 °C (86 °F), whatever the stain.
Does vinegar help with mildew on suede?
It is not needed for mildew. Vinegar is a mild acid that helps with tannin and mineral residue; mildew responds better to the steps above.
Can I use bleach on mildew?
Not chlorine bleach on suede: it leaves permanent pale blotches on suede.
Will mildew come out of suede completely?
Consult a professional experienced with this material. The difficulty rating does not establish that a home method will work.
When should I call a professional?
Suede jackets and anything where water has already left a ring. For this stain in particular, a professional cleaner (tell them it is mildew) has solvents and spotting agents that home kits do not.
What if it has already dried?
On suede, an old mark responds to repeated brushing and the suede eraser over several days; liquids will not help a set stain.
