Can I use oven cleaner (composition: 5-15% aliphatic compounds, 2-aminoethanol, butane and propane...) to clean the carbon off the cylinders and pistons of my BMW R80GS 1991 Motorbike (without damaging it)? I believe they are Nikasil coated, the rest aluminium?
Also, what other household utensils can be used? Brass brush too hard? Toothbrush, steel wool?
