At 60 years old, and having raised a large family, I had become so tired of cleaning. And then along comes Koh. Growing up a hippie I was always in the market for something eco friendly. In fact my cupboards are overflowing with eco products, and sometimes the chemical alternative when eco has let me down. Koh has most definitely NOT let me down. I did approach the purchase with a degree of cynicism, but there’s nothing stopping me now. The oven gleams like new, the stainless steel that always stains or streaks boasts an even glow, the hard floors are fully revived.

The dirtier the job, the more effort you will have to make, just like everything. Nothing in life is perfect, but Koh comes very near!

I was pleased to see that the Diamond sponges are still being made. I was, though, a little bit disappointed in their thickness. The original ones were much thicker and easier to use .Whilst doing the same sort of job as the original ones they are not as firm as the original ones and bend to easily causing problems in their use.

The diamond sponge is an all-rounder. It cleans pans and baking sheets with ease.I have used it to clean the walls before painting, it shifts the grease and dirt with easeon the kitchen walls.It cleans paint if, like me, you manage to go over the edges a bit.You can use it like wet and dry sandpaper.In other words, you can never have too many.

Absolutely fantastic product it cleans the oven perfectly but also we use it for all sorts of jobs, my husband even used it indoor sandpaper it worked like magic. We use it to get any tough stains off. It’s amazing. I’ve just ordered more 🙌

Nothing comes close to the efficiency & effectiveness of these Diamond Sponges.When I first used them, I thought they must be abrasive, like sandpaper … because they removed old, crusty, baked-on grime.Closer examination shows that they are safe for glass & metal surfaces. Surprising!I’ve ordered two more packs - one to gift to a friend.

I used to think magic eraser was great until I tried to clean a pot I'd managed to burn dry!Nothing worked.Until a guest left a pack of diamond sponges and I challenged one with cleaning this pot. It was miraculous, the good pot was saved, and I've used Diamond Sponges ever since for many tough cleaning tasks.Delighted!

I have used this for the oven and grates, greasy and grimy pots and pans, generally very hard to clean things that would require special products and it has worked brilliantly. Only down side is they don't have a very long life which is why I have about 20 in my house just in case. I am yet to find a surface they couldn't clean and without deteriorating the area in any way!

Don't use the diamond sponge on glass - it will scratch
18 January 2022

I used the diamond sponge on a one month old shower screen that had some hard water spots, and it has resulted in bad scratches. I went carefully and made sure to soak the screen and the sponge in Koh and continue to apply more Koh as I went and rub lightly with the sponge. Despite this, the sponge has scratched the glass. This is a new $2,000 custom made shower screen - very disappointed that it is now ruined.

These are the best product of the whole Koh range. They are tough and worked fantastic on cleaning my very old oven. I can now finally clean my oven confidently without the need for hash chemicals. Not recommended for glass, as these will scratch - but the perfect and only tool for tough oven interiors (rails might need a softer sponge for flexibility).

i had received a sample of these with a previous solution order, but didn't really use them. i then ordered a composit sink (worst decision ever!!!) which scratch and stain just by looking at it. i also had a new ceramic hob put in which started getting oil stains which glass scrappers won't budge.then the magic happened!!!one day, i was so annoyed at how my new items were being stained that i thought i'd give these a go with nothing to loose.
