Alchemist 32oz Isopropyl Alcohol is a 99.9% lab reagent / technical-grade isopropyl alcohol in a 32 oz quart bottle. It is a grow-room cleaning consumable: it removes saps and grunge from scissors, blades and equipment quickly and easily. It is a cleaner and solvent, not a nutrient, pesticide, or plant treatment — it is used on tools and surfaces, not on plants.
What it is
This is a 32 oz (quart) bottle of Alchemist isopropyl alcohol at 99.9% purity, sold by carrying retailers as a lab reagent / technical-grade solvent for the grow room. Because it is a very high-purity alcohol, it is a volatile solvent that dissolves organic residues and then evaporates, leaving little water or residue behind — the property that makes it useful for wiping down tools and hard surfaces. “Alchemist” is a house brand carried across the hydroponics trade; the same product is stocked in larger sizes as well.

Why choose it
- High purity. At 99.9%, this is a technical-grade alcohol rather than a diluted drugstore rubbing alcohol, so the higher solvent fraction evaporates cleanly with little water left behind.
- Made for the job. Retailers list it specifically to remove saps and grunge from scissors, blades and equipment quickly and easily — the sticky resin that builds up on trimming tools.
- Handy quart size. The 32 oz bottle is an easy bench size for wiping tools between plants; the same product is also stocked in larger sizes for shops that go through more.
Best uses
- Cleaning trimming tools. Wiping resin and sap off scissors, snips, and blades so they cut cleanly and do not gum up.
- Wiping down equipment and hard surfaces. Removing grime from bench tools and gear between uses.
- General grow-room cleanup. A fast-evaporating solvent for hard, non-porous surfaces.
Compatibility
Use it on hard, non-porous items — steel and carbon-steel blades, scissors, snips, and equipment housings — where a fast-evaporating solvent that dissolves organic residue is what you want. It is a cleaner for tools and surfaces, not a plant input: do not apply it to living plants, growing media, or nutrient solution. Keep it away from anything a strong alcohol can damage — painted, plastic, or rubber parts and finishes can be affected — and always test a small area first. Follow the container’s own handling and ventilation guidance; the full safety data is not reproduced on the retail listings read.
How it compares
| Attribute | Alchemist (this product) | Typical drugstore rubbing alcohol |
|---|---|---|
| Purity | 99.9% | Lower-purity, water-diluted (exact figure varies by product — HELD) |
| Grade | lab reagent / technical grade | Consumer/first-aid grade |
| Best for | Dissolving resin and cleaning tools with minimal residue | General wiping where residue matters less |
The practical difference is the water fraction: a higher-purity alcohol carries less water, so it dries faster and leaves less residue on the tool. The exact purity of any given drugstore product varies and is not sourced here, so it is left HELD in the comparison rather than stated as a number.

Frequently asked questions
What purity is it? 99.9% isopropyl alcohol, a lab reagent / technical grade.
How big is the bottle? 32 oz (one quart).
What is it for? Cleaning tools and equipment — retailers list it to remove saps and grunge from scissors, blades and equipment. It is not applied to plants.
Who this is for — and who should skip it
Suited: growers who need a high-purity solvent to clean resin, sap, and grime off trimming scissors, blades, and grow-room equipment, and who want a handy quart bench bottle.
Not for / its limits: it is a cleaner, not a plant input — do not put it on plants, growing media, or nutrient solution, and it is not a pesticide or a disinfectant claim we can make here. A strong alcohol can damage painted, plastic, rubber, and some finished surfaces, so test first and keep it off anything it might harm.
HELD (not stated because not maker-sourced or not on the sources read): the maker’s brand/product page (hawthornegc.com) returned HTTP 403 to both the sanctioned fetch and an anonymous fetch this session, so there is no maker spec page to cite — the core facts are grounded to carrying retailers. Not published on the sources read: the maker part number (only a retailer store SKU was exposed); the flash point, density, and ingredient detail beyond the stated purity figure; any UL / GHS / lot data; the container material; the case-pack quantity code shown in the SKU title (a distributor pack code — its unit interpretation is HELD); shelf life; and the live retail price (the storefront price is the source of truth at deploy).
