THE BIT THEY DIDN'T PUT ON THE BOX.
The beauty aisle meets the chemistry cupboard.
High-end beauty brands retail specialized brush sanitizers for £18–£25 per bottle. The solution is over 90% high-purity Isopropyl Alcohol (IPA) mixed with a minute fraction of cosmetic emollient. Buying pure 99.9% IPA from an industrial or medical disinfectant supplier provides the exact same sanitation performance for £5 per liter.
SO WHAT'S THE CATCH?
Pure IPA is not the same prepared cleanser, and solvent handling requires care.

Look for complete part numbers and revisions, make sure you're comparing the same quantity, and check the exact model/application. That's especially important with electrical, braking, steering, battery and other safety-related components.
