玻璃損毀了...........怎麼辦?

Question

鋁窗上的玻璃在裝冷氣時給燒焊火花損毀了, 做成一點點啡啡黑黑, 如似落雨噤, 用什麼清潔劑都擦不乾淨,有得救嗎?

Answer 1

Try to cut a fresh lemon in half and wipe it couple times, if it helps, continue to do so.
I did some experiment on this kind of burned stain, and lemon prove to be working.
if lemon won't work for you, try some TOOTH PASTE, the one with peroxide is the best and try to use a clean cloth and keep on rubbing it until it goes away.
