Star brite Corrosion Buster Pen is supplied as a mechanical pen, under SKU 113143 and MPN 91401. A compact mechanical tool for accessible localized deposits where abrasive cleaning is approved. This purchase supplies one adjustable glass-fiber cleaning pen. Select the product by the actual cleaning, protection or surface-preparation task before comparing container size or tool format.
The Corrosion Buster Pen is a mechanical cleaning tool, not a liquid inhibitor or dielectric gel. Manufacturer guidance identifies an adjustable glass-fiber tip for localized rust and corrosion removal in hard-to-reach locations. Because cleaning is abrasive, the exact finish and contact plating need assessment before use. Solvent-free operation does not establish that every delicate surface can tolerate mechanical abrasion.
This listing is one adjustable pen, not a chemical bottle with a treatment-volume claim. Changing exposed fiber length changes cleaning aggressiveness, so use a controlled setting suited to the surface. Plan removal of loosened corrosion and fiber debris before reassembly. Contact plating and protective finishes can be thin and should not be abraded unless the equipment instructions permit it.
For surfaces that permit abrasive spot cleaning. Check contact plating, coatings and equipment instructions before use. Isolate electrical power before maintenance and manage loose fibers and cleaning debris. Follow the complete equipment procedure before returning an electrical item to service. Surface cleaning or a non-conductive barrier does not certify electrical safety or repair damaged parts.

What Customers Say
Battery terminals came clean
Used the pen on crusty battery posts and the small screws on the fuse block. Twist the barrel to set the fiber length, and a short tip cuts the green corrosion without chemicals. Contacts looked bright and the connection stopped acting flaky. It showed up two days after I ordered. For the price it lives in the tool bag.
Saved a sticky reel
The drag knob and line roller on my spinning reel had salt crust sandpaper could not reach. A light pass with the glass fibers cleaned the recesses without soaking the reel in solvent. Retract the tip when you are done so it does not fray in the tackle box. Shipping was quick and the pen arrived sealed.
Radio plug pins cleaned up
VHF connector pins had a dull film and the radio was cutting out. Shortened the fibers for a stiffer scrub, worked each pin, then wiped with a dry cloth. Signal stayed solid the next few weekends. No smell and no runoff in the console. The order was here faster than the site estimate. Handy little tool.
Great on small spots, tip wears
It shines on terminals, hose-clamp screws, and switch contacts, but it is not a substitute for a brush on a big rusty bracket. The fibers also shorten if you lean hard on heavy scale, so twist out only what you need and retract it after. Still a fair price, and Mariners Warehouse shipped it the next day.
Trailer plug contacts work again
The trailer plug was green inside and the lights were intermittent. The fine tip reached the sockets sandpaper never would. A few turns, a short fiber, and the contacts went bright again. Lights have been steady since. Fast shipping, and at this price it is cheap insurance for the glove box.
No chemicals on the console
I did not want solvent near the electronics, so this pen was the right call. Cleaned corrosion off the compass light contacts and a sticky switch with just the glass fibers. Rotate for length, and keep it shorter when you need more bite. The package arrived intact in a couple of days. Good value for how often I will use it.
Keeps the tackle in shape
Works on reel seats, guide feet, and the little screws that bloom after salt weekends. I twist a short tip out, scrub, and retract it so the fibers stay protected. It does not smear grease around the way a wire brush can. Showed up quickly, and the price is easy to justify for something this precise.
Precise and simple to use
Followed the directions: adjust the fiber length by rotating the body, keep it short for stubborn spots, then retract. Cleaned the chartplotter power plug and a pair of corroded spade connectors without marking the plastic housing. It does exactly what you want in a tight space. Shipped fast and worth keeping aboard.
Frequently Asked Questions
What does SKU 113143 include?
One cart unit supplies one adjustable glass-fiber cleaning pen. The listed code is 91401.
Is this a liquid corrosion inhibitor?
No. It is a mechanical glass-fiber cleaning pen. It does not itself supply a protective inhibitor film.
How is cleaning aggressiveness adjusted?
Manufacturer guidance says to rotate the body to adjust fiber length. Shorter exposed fibers provide more aggressive cleaning.
Is it suitable for every plated contact?
Do not assume so. Check plating and equipment requirements; mechanical abrasion may be inappropriate for some surfaces.
Does solvent-free mean no precautions are needed?
No. Follow the pen’s protective measures and manage fibers and debris. Electrical servicing still requires isolation.
What should I do after use?
Remove cleaning debris as the equipment procedure requires and retract the fibers to protect the tip during storage.
Why does the supplied format matter?
This purchase supplies one adjustable glass-fiber cleaning pen. Use its exact label rather than transferring instructions from a different format or formula.
How can I check suitability before ordering?
Contact Mariners Warehouse with SKU 113143, code 91401, the equipment and surface details. Confirm the exact task, package and directions before use.
