The present invention relates to a cleaning composition for cleaning airct wheel wells. The cleaning composition broadly comprises from about 0.1 to about 15% of a D-limonene composition, containing less than 0.5% of a stabilizing anti-oxidant, acting as a solvent for said greasy soils, from about 0.1% to about 5.0% of a material for increasing the flash point of said cleaning composition above 140.degree. F., such as an isoparrafinic hydrocarbon solvent, from about 10% to about 50% of a mixture of linear alcohol ethoxylates having a HLB in the range of 2 to 15 as a stabilizer, and the balance water. The cleaning composition may also contain from 0.1% to about 10% capryolamphopropionate, from about 0.1% to about 15% dipropylene glycol, from about 0.1% to about 5.0% benzotriazole, and 0.1% to about 5.0% sodium bicarbonate.

The cleaning composition may also contain from 0.1% to about 10% capryolamphopropionate,from about 0.1% to about 15% dipropylene glycol, from about 0.1% to about 5.0% benzotriazole, and 0.1% to about 5.0% sodium bicarbonate.

The present invention relates to a cleaning composition having utility in eaning aircraft exterior surfaces. The cleaning composition comprises from about 15% to about 40% of a mixture of linear alcohol ethoxylates having a HLB in the range of about 5.0 to about 15.0, from about 5% to about 25% capric diethanolamide, and the balance water. The mixture of linear alcohol ethoxylates comprises from about 5% to about 15% of a first linear alcohol ethoxylate having a HLB in the range of about 5.0 to 9.5 and from about 10% to about 25% of a second linear alcohol ethoxylate having a HLB in the range of about 10 to 15. The cleaning composition also includes from about 0.1% to about 5% of capryloamphopropionate, from about 0.1% to about 5.0% benzotriazole, from about 0.1% to about 5.0% of an inhibitor for reducing corrosion of magnesium parts, and from about 0.1% to about 5.0% of an inhibitor for reducing corrosion of cadmium plated steel parts.
