Which Selleys mould removal product do you need?
This category is straightforward, because there is one product in it in two sizes. Selleys Rapid Mould Killer is the fast and effective way to get rid of mould in your home, and the only decision to make is how much of it you need: the 500mL for ordinary household mould, or the 750mL, which Selleys describes as the option for removing mould in larger areas.
Buying the larger size is worth thinking about before you start rather than halfway through. Mould rarely stops at the patch you can see, and running out mid-job means treating an area in two passes at different times, which is how a colony survives a treatment.
What this category covers
Mould removal and mould cleaners within the Selleys cleaning and maintenance range. Selleys describes the purpose of the category as helping keep your home healthy and clean by effectively removing mould and preventing it from returning.
The product listing on the live category page is loaded dynamically, so the two sizes below are what can be confirmed rather than necessarily the whole current range.
The products in this range
| Product | Size | Selleys' description |
|---|---|---|
| Selleys Rapid Mould Killer 500mL | 500mL | The fast and effective way to get rid of mould in your home; powerful and easy to use. |
| Selleys Rapid Mould Killer 750mL | 750mL | A powerful solution for removing mould in larger areas. |
These are the same product in two pack sizes, so there is no performance difference to weigh up — only coverage. Check the individual product pages for the surfaces each is suitable for, the dwell time, and the safety directions before use.
Common questions about Selleys mould removal
What is the difference between the 500mL and the 750mL?
Size. Selleys presents the 750mL as the option for removing mould in larger areas; both are the same Rapid Mould Killer.
Which size should I buy?
Judge it by the area you intend to treat in one go. If you are treating a whole bathroom, a ceiling, or several rooms, the larger pack is the one described for larger areas.
Does it stop mould coming back?
Selleys describes the mould removal range as helping keep your home healthy and clean by effectively removing mould and preventing it from returning. For the specific claims and how long that protection lasts, check the individual product page.
What surfaces can I use it on?
The category text does not list surfaces. Read the directions on the product page and on the pack before using it on any surface you are unsure about — this is a chemical product and the label is the authority.
What about mould in silicone sealant?
That is a different problem from surface mould, and it is generally a sealing question rather than a cleaning one. Sealants formulated to resist mould and mildew growth are covered under wet area silicone sealants, which is a separate category from mould removal.
Why are only two products listed here?
The category page's product listing is generated dynamically and could not be captured, so only the two Rapid Mould Killer sizes confirmed in the site's own listing are shown. Check the live mould removal page for the current range.

Does Selleys Original Sugar Soap kill mould spores?
No, according to the knowledge base, Selleys Original Sugar Soap can clean visible mould and mildew from surfaces indoors and outdoors, but it does not kill mould spores, so mould may return if conditions remain conducive to growth.
What additional steps are recommended to prevent mould from returning after using sugar soap?
To help prevent mould recurrence after using sugar soap, a bleach-based cleaner can be applied afterward to kill mould spores (rinsed thoroughly, with disposable gloves and protective eyewear worn for safety), or alternatively, a white vinegar solution can be used to kill mould spores on surfaces.
