Excellent product & value (when on sale)

M TruthAugust 4, 2025✓ Verified purchase

Easy to apply and work around. Cleaned terminals fast. To remove just use small sprayer and wet rag to clean terminal areas. Ensure you dry areas outside battery terminals. Recommend storing can per manufacturer's instructions. Always wear plastic gloves and eye protection!!! Recommended! Read more

Great cleaner, mostly good for acid checker

real good acid checker, but could always use the old baking soda/water method for cleaning though Read more

Cleans Corrosion Better Than Wire Brush Alone

KNSeptember 22, 2025✓ Verified purchase

I've tried this on my truck battery, which tends to get corroded quickly. I sprayed the cleaner on both terminals and let it sit for a while to work. Rinsed off with water, then scrubbed the terminals with a small brass wire brush. I'm left with clean terminals, and I hope, no acid to continue corroding the terminals. After several weeks, the terminals are still clean. Read more

Once every few years... just do it right...

Works as it should You must rinse off the spray...so if you can get your hands on a steam sprayer...its a lot less messy Read more

Workign great on corrosive stuff. Amazing job!!!

Dissolved the corroded battery 🔋 ends in seconds. Gotta be careful while using it. Wear a mask or cover your mouth and nose. Also wear protective glasses. Definitely worth buying it. Not that thick. Just sticks in and eat up all the corrosive stuff. Comes in a good size. Easy to use also. Read more
