MG Chemicals - 824-1L 99.9% Isopropyl Alcohol Electronics Cleaner, 945 mL (1 Quart) Liquid Bottle, Clear, 32 Fl Oz (Pack of 1)

This Isopropyl alcohol is great for electronics cleaning. The high 99.9% purity leaves no residue and dries almost immediately.The high evaporation rate of the product is the reason why multiple sealed bottles, in my opinion, are better. Instead of having an open 1 gallon or 5 gallon container, which internally evaporates faster -- due the larger surface area of the product in in a large container -- to reach internal equilibrium with a larger volume of air, these multiple sealed ~1L bottles allow you to store the product with less worry about evaporation and limits the amount lost since you'd only have a 1L bottle open as opposed to say a ~3.785 L (1 gal) bottle.Diluted 2:1 with distilled water gives ~66.5% strength (or 7:3 for 70%) which is better for disinfecting than 91% or 99%. Used at full strength makes a great cleaning solvent.There are cheaper, larger containers available on amazon but for the convenience this product provides and its trustable purity, this seems worth it to me.

Amazing product.

This 99.9% isopropyl alcohol by MG Chemicals is a must have for the electronics technician or the electronics hobbyist. Because it is 99.9% anhydrous it is safe for circuit boards as there is no water and because of this, it is quick drying.I use it as a flux remover on circuit boards and to clean electrical connections. I've used it on tube sockets and tube pins. Being anhydrous is an added benefit on wafer style tube sockets, where water would cause all kind of issues. I actually used to use 91% off the store shelf and had an issue with a radio that I had cleaned the tube wafer sockets, the 9% water was left over and the radio failed to operate until the water evaporated from the sockets. That is when I switched to 99.9% anhydrous isopropyl alcohol.It also works great in removing disintegrated belt goo on tape deck mechanisms and turntables.Keep in mind that this is not for use on your skin unless you dilute it with water. If you do use this to clean electronics I would advise to wear nitrile gloves when doing so. Overall a great product, might be a bit pricey for 1Qt. but overall it is worth the extra bucks.

This is 99% isopropyl alcohol and it cleans flux from circuit boards quickly while leaving no residue. It is expensive but worth it to keep around (and tightly sealed).

Always an excellent product from MG Chemicals. Sturdy bottle with child-resistant cap and foil covering. No leaks from shipping. Size is excellent for price.

I did not use this and simply it away to a friend, but she has said she likes using it to clean everywhere, from her bed and nightstand to the ceiling vents! I sometimes wonder if she is made of alcohol as everything in the house seems oddly sanitized with every visit. Nonetheless I have not heard any complaints, and for that I give this electronics cleaner a respectable 4/5!

I repair vintage electronic equipment (particularly vintage audio equipment). I use various MG Chemicals' products and have been pleased with all of them. I use this 1L bottle of 99.9% isopropyl alcohol to refill a small (non-MG) needle bottle. I use the needle bottle for active work, then refill when necessary. Works well.

Great productNice large size bottleNo leaks, no odor no evaporationUse for electronics repair
