Wonder Gel pickles and passivates stainless steel in less than fifteen minutes. It removes rust and contamination caused by welding, abrasion, and exposure. After one easy application, it cleans the surface and restores the chromium layer essential to the preservation of stainless steel.
Hazardous material (UN3093, Class 8, PG II). Ships with special handling; a shipping surcharge applies. For industrial / professional use.
Long shelf life — stored sealed at normal room temperature, our chemistries stay effective for years with no fixed expiration date. Keep containers closed and protected from freezing and direct sunlight. Buy the larger sizes to save without worrying about product going bad.
Formulated to meet ASTM A967 (passivation) and ASTM A380 (cleaning / descaling / passivation).
Wonder Gel wiping away weld heat tint on stainless steel.
Wonder Gel is a stainless steel pickling and passivation gel that removes weld heat tint, slag, oxide scale, and surface contamination — and restores the protective chromium-oxide layer for maximum corrosion resistance — in a single brush-on step. No electricity, no expensive electropolishing equipment.
Because it's a clinging gel, it stays put on welds, vertical surfaces, and complex geometry that dip tanks and mechanical methods can't easily reach. Brush it on, let it dwell about 10–15 minutes, and rinse with water. The result is a clean, uniform, passivated surface that meets ASTM A380 (cleaning/descaling) and ASTM A967 (passivation).
Trusted for over 50 years across welding and fabrication, medical and surgical instruments, food and dairy equipment, aerospace, and marine work. Available in 8 oz, quart, gallon, and 5-gallon. NSF Nonfood Compounds registered, made in the USA.
Frequently asked questions
How do you use Wonder Gel?
Clean off oil and debris, brush the gel onto the weld or contaminated area, let it dwell about 10–15 minutes (longer for heavier heat tint), then rinse thoroughly with water. Always follow the SDS and wear proper PPE.
Does Wonder Gel both pickle and passivate?
Yes. It removes heat tint, slag, and scale (pickling) and leaves a passivated surface with the chromium-oxide layer restored — in one application.
What grades of stainless does it work on?
It's used across common austenitic stainless grades such as 304 and 316, as well as other stainless alloys. Test on a small area if you're unsure.
How long does it take to work?
Typically 10–15 minutes of dwell time depending on the severity of the heat tint and the temperature. Heavy discoloration may need a second application.
Is Wonder Gel safe for food or medical equipment?
It is NSF Nonfood Compounds registered (Category A3) and widely used to passivate stainless for food, dairy, and medical/surgical applications. Rinse thoroughly after use per the instructions.
Does Wonder Gel expire? What's the shelf life?
There's no fixed expiration date. Stored sealed at normal room temperature, Wonder Gel stays effective for years — so you can buy the larger sizes to save without worrying about it going bad. Keep the container closed and protect it from freezing and direct sunlight.
