You walk around the airplane on preflight and spot it: a thin red streak running down the inside of a wheel pant. Most light general aviation airplanes use a red, mineral-based hydraulic fluid in their brake systems, and that red dye is there so leaks are easy to see. A weeping brake line or caliper leaves exactly this kind of mark, and it collects dirt until the gear leg looks permanently grimy.
Hydraulic fluid isn’t the only stubborn contaminant on an airplane. Summer asphalt sends tar up onto the belly and gear fairings. Removing old registration numbers, stripes, or tape leaves a gummy adhesive film behind. Oil mist from the breather finds its way along the belly. Ordinary soap barely touches any of it, and aggressive solvents can dull paint or craze plastic. What you want is something strong enough to dissolve oily, sticky residue but gentle on the surfaces underneath.
One important note before cleaning: a fresh hydraulic fluid stain is also a maintenance clue. Cleaning the streak off doesn’t fix a leak. Wipe it clean, watch whether it comes back, and if it does, write it up for your mechanic before the next flight.
Quick answer: Aero Cosmetics SafeSolv 32 fl. oz. is an all-purpose citrus solvent that removes tar, oil, hydraulic fluid, adhesives, and gum. Aero Cosmetics describes it as a non-toxic alternative to harsh chemicals that’s gentle enough for paint, plastic, glass, bare metal, carpet, and seats, inside or outside the airplane. It’s available on Skyfarer and at Skyfarer Shop.

Frequently asked questions
Is SafeSolv safe on aircraft paint?
Aero Cosmetics says it’s gentle enough for paint, plastic, glass, bare metal, carpet, and seats. As with any solvent, test a small hidden area first, especially on new or touched-up paint.
Can I use it inside the cabin?
Yes. It’s intended for interior and exterior use, including gum or sticky residue on carpet and seats. Apply it to a towel rather than spraying near avionics.
Should I just keep cleaning off hydraulic fluid streaks?
No. If a red streak keeps reappearing near a brake or strut, it points to a leak. Clean it so you can monitor it, and have a mechanic inspect the system.
