Manufacturer description
MG Chemicals 824-1L is a 99.9% anhydrous isopropyl alcohol electronics cleaner supplied in a 945 mL (1 quart) liquid bottle, built for the kind of contact and board work retro PC builders do constantly. Because it is anhydrous rather than the 70% pharmacy grade, it actively pulls water and humidity out of components and flashes off dry, which matters when you are reviving a socketed CPU, a corroded ISA edge connector, or a sound card that has spent a decade in a damp basement. Residue is held under 0.001 g/100 mL non-volatile content, so contacts come out clean instead of tacky. The…
SpecPicks Verdict
SpecPicks scored MG Chemicals using a rating × review-volume × price-fit model applied to published specs and reviews across the tools & maintenance category. MG Chemicals's tools & maintenance lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for tools & maintenance: PC towers accumulate significant dust in 3–6 months, so cleaning frequency drives cordless vs. canned-air tradeoff decisions. Match the device's RPM or CFM rating to your case size, and confirm battery runtime covers a full tower cleaning before ordering.

Frequently Asked Questions
Is this the same as the 70% isopropyl alcohol from the drugstore?
No. This is 99.9% anhydrous isopropyl alcohol, which contains essentially no water and evaporates faster and drier than 70% grade, making it better suited to boards and contacts.
Can I use it to clean flux off a circuit board after soldering?
Yes. MG Chemicals lists flux among its intended uses, along with printed circuit boards, connectors and contacts, semiconductors, relays, fibre optics and tape heads.
Will it leave residue on gold-plated edge connectors?
Non-volatile residue is specified at less than 0.001 g/100 mL, so it is formulated to flash off without leaving a film on contacts.
How much liquid do you actually get?
The bottle holds 945 mL, which is one US quart, supplied as a liquid in a pour bottle rather than an aerosol or pump spray.
Does it meet any formal standards or certifications?
It meets reagent ACS grade, MIL Spec TT-I-735A and ASTM D770, and holds NSF International registration #144029 as a non-food chemical for food facilities.
