How to remove green stains on glass


Recommended Posts

I have some very stubborn green algae stains on glass that I can't seem to scrape off. How can I remove them? I am using this Kent Marine scraper with a metallic (aluminum?) blade. I can easily remove those normal algae growth but not on these stains. Any suggestion?

No other way bro, but good old elbow grease... ;)

If you have unwanted credit card, or other card of similar materials - those are quite useful to scape off the stubborn algae. It works for me.

Best to do scrapping of glass while doing WC.

For me I use an unwanted credit card material and scrape the glass in an upward direction, then siphon it out the algae so it won't spread.
