This is gonna sound daft but,can you clean windows in the rain using wfp system.The reason i ask this is because one guy i know who uses wfp everyday claims that the water you purify is the same as rain water.

1) yes you can clean windows in rain with wfp providing not pouring down and lashing off windows
2) rain water does not have the same purity as pure water used in wfp , the water we use has a tds reading of 000ppm rain would would be a lot higher reading

Yes it cleans in the rain.

I clean in light and medium rain, but not in heavy rain.

Rain water has a TDS reading of around 12 - 20
