Parts Stop stocks the two INOX workshop staples: MX3, the original anti-corrosion penetrating lubricant, and MX2, the battery terminal conditioner that stops corrosion building on posts and connections. On the shelf, ready to go.

INOX is Aussie made and owned — Candan Industries in Queensland has been making it since 1989 — and MX3 earns its spot on the differences from a generic penetrant: no silicone, acid, kerosene or dieselene, so it frees seized nuts, bolts and hinges and leaves a lasting anti-corrosion film without harming hard plastics, paint, fibreglass or neoprene seals. That's why it's safe to reach for around wiring, trim and painted surfaces where a harsh penetrant would do damage. MX2 does the same protective job on battery terminals — clean, coat, and keep the green corrosion away.
