A few days back I was browsing the internet and I cam across an interesting article on how to clean your windscreen using lemons. I tried this method and it gave a satisfying result. I justwanted to share it with my fellow PWs.
This method is cheap but effective. You can get lemons from any vegetable shop very easily.
1) Cut the lemon in 2 pieces.
2) Squeeze the lemon and wipe it all over the windscreen.
3) Wait for couple on minutes and then wash it off using water.
A few drags of the lemon on the wiper will clean them too.
Vinegar also gives the same result.
The principle on which this works is that lemon and vinegar are acidic. It dissolves grime and salt deposits very well. Also it works really good to dissolve oily residue on the windscreen.
