The best plan is to prevent/avoid the situation; but of mice and men, the best plan may fall through. On Saturday morning I found my left fairing electronic control panal with white residue and drips of brake fluid from the clutch matser reservoir. The two JIS screws were loose and the fluid had seeped from the top gasket. The painted fairing under the electronic control panal also had white runs on it and the trim strip had wrinkled/soft paint. The Hazzard button was gummy. I used hot soapy water to flush the area and acetic acid formula Windex to clean with toilet paper to absorb as much as possible. When I would clean it, it the paint would turn black again, as it dried it was white. Very ugly for sure. The wrinkled paint on the trim strip acted like wet decal material and I pushed it back into place fairly well but still guly white blotches. I then used some All Purpose GO-JO Hand Cleaner to coat the affected area and the wiped it clean. The paint stayed black, is still black tonight (Sunday). The "scars" on the panel still show if you look close, but the fairing "fared" pretty well. The trim strip has to be replaced.
So, if it happens to you, think to try GO-JO Hand Cleaner, the non-abrasive type, of course.
