 |
|
Hi all .
I have been trying different methods for removing algae getting attached to glass occasionally, including Rs 500 + Magnetic scraper and putting hand inside with old plastic credit card etc. But today when I saw my wifes chapathi tweezer in kitchen I got an idea and it soon transformed in to a cheap but effective scraper for algae.
disadvantages of magnetic scrapers are
if any sand or hard particles goes in between magnetic scraper it creates scratch in glass. also it is costly.
IN case of this cheap scraper,
The blade can be replaced as it is ordinary razor blade and the tool become very effective
To make one needs:
1: A stainless steel chapati Tweezers ( ~rs 50)
2) An ordinary razor blade (<rs 2)
Just straighten the tweezers and make the arm type area flat and make a hole there at the end. Use a small nut and bolt ( it can be taken from an old switch or so) to fix blade at the end . The scraper is ready.
take care of your wife coming after you with chapati stick......
with best regards,
Sudheer |

Thanks Emma,
I saw the LFS scrapers which had fixed not sharp blades which are effective when there is a thick layer of algae but this can remove even the thinnest layer of algae |

thanks all,
@Sai 1 blade can last 2-3 months Sai if care is taken not to hit the bottom, it can even last more . If it hits bottom then its sharpness goes.
Hi Ruchit and other doubtful,
Blade can never make scratch on glass. It is the funda of hardness, if you have doubt you take a piece of glass and take all your strength to make a scratch on it using a blade. But what blade can not do can be done with smallest piece of quarts ( sand particle) because its hardness is same or more than that of glass depending on composition.
@swapnilk
I gave up those magnetic dusters as the issue is what I mentioned, by mistake if a sand particle goes in between glass and the magnet you will have all your glass with scratches...

For those unaware, razor blade is also used to scrape white water-stains on old tank glass.
Good DIY Sudheer. |

Live tested it... seriously I feel Im scratching it but there is no mark on it!!
but be careful that you dont scrape off your silicon as well 
Sudheer,
Any reason to not use the shaving set itself? it will be safer to use if it works.
...and by bottom you mean Tank bottom(substrate)? or edge of algae(glass surface)? |

Common Sai, so you went to test it!!. if a blade can cut glass why people will use diamond cutters for cutting glass?, but if you have a sharp quartz grain it can cut glass for you.
Shaving set?? How can it be made close to the glass wall at required angle to remove algae? In shaving sets blade get fixed ( old type) at right angles to the handle, it is difficult to get the blade in contact with glass.. which ls flat unlike your face....
I meant the blade hitting sand substrate.
you are correct one need to be care full not to scrape off silicone!!. |

Science of shaving!! this asks for a paper on its own.
Please see if you can plan for a guard over it, to avoid human mishaps.
Cheers. |
