WD-40 Specialist Fast Release Penetrant
Seconds, not minutes. Maximum force. Instant gratification.
by WD-40 Company
For when you can't wait. WD-40 Fast Release works in seconds, not minutes. The blast-cap technology delivers maximum force with each spray, driving the formula into seized parts with authority.
The proprietary blast-cap delivery system creates a burst of pressure that forces the penetrant into microscopic gaps conventional sprays simply can't reach. Independent testing shows it breaks the bond on rusted fasteners 30-40% faster than standard penetrating oils, though it trades staying power for speed. Think of it as the espresso shot of penetrants — intense, effective, and over before you know it, so keep a follow-up lubricant handy for long-term protection.
What We Like
- + Blast-cap technology delivers a powerful burst that gets deep inside on the very first thrust
- + Works in seconds — no waiting around for penetration to happen
- + Capillary action pulls the formula deeper into the tightest crevices
- + Loosens even the most stubbornly stuck nuts with minimal effort
What Could Be Better
- − Evaporates quickly — not a long-lasting experience, more of a quickie
- − Strong chemical smell lingers and may require ventilation afterward
