Isopropanol Alcohol 99.9%, 500ml - High-Purity Isopropyl Alcohol IPA, Solvent & Cleaner For Electronics, PC & Phone Cleaning, Ink Removal, Surface Prep, Lab & Industrial Use

This isopropanol alcohol is excellent value for the quality and purity you get. It works exactly as expected, fast evaporating, clean and reliable, whether you are using it for electronics, surface prep or general household cleaning. The bottle size is practical, the performance is consistent and it is noticeably better than the cheaper, lower purity alternatives. For the price, it is a solid buy that does the job without fuss.

This is wonderful stuff and excellent value for money. I was looking around Amazon and finding bottles half this size for almost twice the price. I wanted to try this stuff after getting a paint stain on a T-shirt that I wanted to clean out. It was one of those "another quick dab of paint, no need to change, I won't mess it up" moments, and we all know how they go... as soon as I turned round I brushed the wall - oops. A quick was in very warm water then I used this undiluted with an old toothbrush to scrub at the paint. 60 seconds was all it took, absolutely delighted. After I did the shirt I tried it on some of the old brushes I'd been using for the chalk based wall paint and it was fantastic. Soaked them for a while then gave them a scrub and a rinse. It's not a miracle and it wont' bring everything out first time, but it's an awful lot better than I was expecting. Great stuff, super value for money for a bottle of this size, I'll be ordering this again. Why pay more? Recommended and I hope this was helpful.

Great general purpose electrical contact cleaner. Put a small drop on a cotton bud and gently apply. It dries in seconds leaving no residue.

Honestly I love this stuff, perfect for cleaning electrical parts in my pc. Removed thermal paste so easily, scent free streak free too.

This doesn't always evaporate as fast as I expect for Isopropanol at 99.9%. I am a little suspicious about its purity level. I could be wrong. Various indicators are not conclusive that it is a lower strength. It does do noticeably IPA things when it comes to cleaning but as I say, stays wet longer than I expect. Apparently you can test density to indicate purity by the following with a syringe and scales. The figures to look for are if you really want to know whether it's close to 99.9% with this simple home test are: Weigh an empty small container. Add exactly 10.0 mL of the IPA (a syringe is ideal). Weigh again. At about 20–25 °C: ≈7.85 g for 10 mL → very close to pure IPA. ≈8.1–8.3 g → contains a noticeable amount of water. ≈9.0–10.0 g → mostly water. I don't have either a suitable measuring method available or sensitive enough scales........but if you do....... Good price for 1 litre of this stuff for sure and bottle and presentation and packaging were all very good.

Big bottle that does what it says and cleaned both mine and my sister's PCs and peripherals.

Perfect for what I needed it for. Bottle is a great size and the lid is very secure. It's very strong smelling but I'd be worried if it wasn't given what it is!

Good value with extreme cleaning power. Can be diluted for certain applications. Use with care.
