Note, July 2026: This page used to link the Mould Magic Extreme Gel. Amazon UK now lists it as "currently unavailable, we don't know when or if this item will be back in stock". We have repointed it to Inpumo's gel, which occupies the same slot. Consider that a live demonstration of the warning below: in this corner of the category, the listing you buy today may not exist next year.
Inpumo Mould Remover Gel Review (and the Whole Import Gel Category)
Format: 2-pack gel, usually paired with a brush; sizes vary by listing
Active ingredient: Not fully published on most listings
Price: Check current price; typically the cheapest gels on Amazon UK
Dwell time: Several hours to overnight
Best on: Grout, sink silicone, small jobs where budget rules
Search "mould gel" on Amazon UK and you'll find a wall of near-identical products: Inpumo, Mould Magic, Magic Extreme Gel, UK Magic Gel, and a rotating cast of names that look like they came out of the same factory because many of them did. This review covers the brush version we link, but read it as a review of the whole category, because the individual listings change faster than we can re-review them. The product this page originally covered went unavailable within a year of publication, which is exactly the point.
What you get
A generous quantity of thick gel, usually a small brush, and a price that undercuts Skylarlife substantially, often for more product. The gel format works here the same way it works everywhere: it clings, it dwells, and given hours of contact it lifts black staining out of grout and silicone. Plenty of owners report results comparable to the branded gels, and on straightforward jobs, sink surrounds, grout lines, tile corners, that matches what the format should deliver.
What the listings don't tell you
This is where we earn our keep. Most of these listings publish incomplete or no ingredient information. There's rarely a proper safety data sheet, the brand name on the box may not match the listing, and quality can vary between batches because "the brand" is often just whichever importer bought this production run. You're almost certainly getting a hypochlorite gel, but "almost certainly" is doing real work in that sentence, and you should treat the product with full bleach precautions either way: gloves, ventilation, and absolutely no mixing with other cleaners. Our bleach safety guide applies double when the label tells you less.
Pros
- Cheapest entry into the gel format
- Multipacks go a long way
- Usually includes a brush
- Fine results on routine grout and silicone jobs
Cons
- Incomplete ingredient and safety labelling
- Interchangeable brands, batch to batch variation
- Listings appear and vanish; hard to rebuy the same product
Verdict
Buy it if budget is the deciding factor and the job is small. It will probably work, and the format is the right one. Spend up to Skylarlife when you're treating a whole bathroom, when you want to know exactly what's in the tube, or when you'd like to buy the same product twice.
