08 Questions
Is diluted WD-40 safe on suede?
No. Dilution slows the damage but does not change what WD-40 does to suede: it leaves a permanent dark oil patch in suede.
What should I use on suede instead of WD-40?
Use the method in the stain file for the specific stain: on suede the right product depends more on the stain than on habit.
Can I mix WD-40 with other cleaners on suede?

None of the 25 files for suede uses it. Absence from the model does not establish either effectiveness or safety.
How long can WD-40 stay on suede?
Do not use it as a routine home treatment on this material. For accidental contact, follow the product and item instructions and obtain advice if needed.
