We first purchased Impresa Descaling Solution nearly 5 years ago, when our Keurig began having problems with dispensing. We hadn't descaled the machine at all for over one year but it was back up and running great after using the Impresa Solution. I followed the directions and noticed no aftertaste to the first cup of hot water out of the machine.A little later, we decided to upgrade to a Nespresso. Lesson learned from the Keurig was to not wait, so again the Impresa solution was used to descale and worked great with no aftertaste.Again we upgraded, this time to a Phillips LatteGo 3200. The descale light comes on, so I reached for the Impresa solution but noticed that Phillips is not included in the named brands. As others here have also noticed, there ingredients are not listed. Hmmm...After reviewing the Phillips owners manual, the section on Descaling specifically states, "Please use Philips descaler only. Under no circumstances should you use a descaler based on sulfuric acid, hydrochloric acid, sulfamic or acetic acid (vinegar) as this may damage the water circuit in your machine and not dissolve the limescale properly. Not using the Philips descaler will void your warranty."As an Engineer who began his career designing plastic and rubber parts, I knew where to find the manufacturer's ingredients. I've included a snip here of the main ingredients and their concentrations. (For those wondering what the rest of the bottle contains, it;s di-hydrogen monoxide aka water.)Now we have problem because the two main ingredients listed in Impresa's formula will specifically void your Phillips warranty. So if you're withing the 12 month warranty period and are prone to descaling your machine it could be an issue. But also highly unlikely.The only parts likely to be affected in the machine are the o-ring seals. After looking at them and doing some research, it's pretty clear they are a type of rubber called fluoroelastomer (FKM for short.) This type of rubber is good in high temps, durable, resistant to acids (including both used in the Impresa Solution), and it has a food grade version that is FDA approved.The o-rings could also be a type of silicone but that's less likely because they easily tear and attract dirt/debris. We've had our machine for 3+ year and as often as we use it, I'd expect to see small tears or cracks if they were silicone but there are none. If anyone has a spare Phillips o-ring, please stick a lighter under it and let me know the results: Silicone will burn and smell sweet. FKM will not easily burn and will stink if/when it does.So overall, I have no concerns about using Impresa Descaling Solution in my Phillips as far as impacting or damaging the machine.As far as food safety, the first ingredient is 7-10% Citric Acid. This one of the most common food additives in the entire world, and you will be hard pressed to go through your entire household and not find it as an ingredient. You will notice that it's classified as 2A which means it will irritate your eyes, the same as vinegar, lemon juice, or any other acetic acids. So it's perfectly safe unless ... you put it in your eyes. So don't do that. It will hurt.The second ingredient is 3-7% Sulfamic Acid. Sounds ominous, doesn't it? But it isn't. SA is used all over in food production for cleaning off equipment, from beer brewing and the dairy industry to ... you guessed it ... coffee and espresso shops. This is the main ingredient for removing limescale. It's rated as Category 2 Compound for both Eyes and Skin so again, don't pour it in your eyes AND don't use it as a moisturizer on your skin. It will hurt. Once it starts to hurt you're going to wash it off. And then you'll be OK.TL/DR: Great descaler for Keurigs, Nespressos, and Phillips machines. The ingredients are well-known and highly safe for use.

They did ok. I don't know what the expectation is but I had to do 3 or 4 sessions to get the coffee pot humming again. Thought this would work better than it did.

Used on our Kcup/coffee dispenser. Did a GREAT job cleaning it (ashamed to say it has been a number of years). Appreciate there is more to use for a later date (that won't be years from now ;-)

I've had a bit of trouble with buildup in some condensate pipes leading outside. Found this and put it in all systems per the instructions. I'm hopeful it will work, only significant time will tell and I'll update this review.

I was incredibly impressed by how well this de-scaler worked on my ninja coffee machine. We had moved from a house that was running on well water to a house that has city water, and after two years of the coffee machine using well water, it had a lot of mineral and scale buildup. After following the recommended instructions and only using half a bottle (I thought surely I would have had to use a whole bottle), my water reservoir was completely clean!! The amount of iron and white residue that filtered through into my coffee pot was unreal. I’ll definitely be using this again in the future.

This descaler worked OK, but it left an unpleasant smell and taste in the coffee and machine after. I had to run my Nespresso descale program all over again with plain water after, just to flush the taste and smell out. Would not buy again.

Go by the coffee makers directions. Ignore the directions on the bottle.For Keurig use the whole bottle and use the buttons to engage the descale mode.
