DIYChemicals Heptanes –- Industrial Grade Heptane Industrial Nonpolar Solvent for Cements, Ink, Extractions - Made in USA - 5 Gallon

I purchased this to see if it would help in the removal of self-adhesive postage stamps. It works wonderfully on the glossy self-adhesive stamps. I am now able to add these stamps to my collection without the paper being left on them. Some papers will make the stamp deteriorate over time so this is perfect for that. It also removes unwanted labels, etc. from boxes, bottles and other items. Love it and will be buying more.

If quality is king, use heptane in the extraction.

Good price, but I'll have to puncture the bottle and find a new container to put the heptane in as the cap is impossible to remove. Pushing down as hard as I can and turning, it just clicks and will not open. I bought the half gallon and so it came in two 1 quart bottles and they're both doing it.

Good product for extracting

Seal came broken and chemical spill all over with lots wasted heptane and a mess to clean and headache and sick because inhaled the vapors, just don’t buy this for health and safety reasons
