| Why it was picked | It is the supermarket default for good reason, and on tiles and sealant it shifts the black quickly with no scrubbing. (Best mould removers) | The chart leader, and the only one of the six whose own listing says in plain words that it kills black mould and mildew and prevents regrowth. It is a bleach-based spray, so it works fast on grout, sealant and plastered walls, and it is the cheapest thing here by some way. (Best mould removers) | Active bleach, no scrubbing needed, and the brand most people already trust in a cleaning cupboard. (Best mould removers) | A liquid spray on a bathroom ceiling ends up on your face and down your sleeve, whereas the foam sits where you put it and gets the contact time it needs.

Look Into researches products from published sources: makers’ pages, retailer listings and regulators. We have not handled or tested these products, and a blank field means we have not recorded that figure yet, not that the product lacks the feature. Awards are Look Into editorial picks, not Amazon or third-party awards. As an Amazon Associate, Look Into earns from qualifying purchases; commission never decides a ranking.
