Is any of this happening?
Be seen today
Contact a poison centre promptly after swallowing mildew remover, breathing substantial fumes, or having ongoing symptoms.
Call while rinsing an eye or skin exposure rather than waiting for rinsing to finish.
Urgent medical assessment is appropriate for severe or persistent eye pain, blurred vision, blistering skin, repeated vomiting, wheezing, shortness of breath, or a cough that is getting worse.

Does any of this apply?
Book an appointment
Routine follow-up is reasonable if mild symptoms are improving but do not fully settle, or if cough, wheezing, skin irritation, vision changes, or swallowing discomfort continues after the initial assessment.
Every sign above is quoted from the sofidex article on Mildew remover poisoning. If you are not sure, err upward — it is always reasonable to be checked.
