Top Glass Panels - How To Clean

[clivealive]

hi

anyone any idea's on the best way to clean the top slidey glass. i cant remove them as its an old style tank.
so will need to be cleaned while still in the tank.

also what wont scratch the glass that can be used to help, that wont scratch the glass.

I have used jbl bio clean but still not really getting anywhere.

idea's welcome.

I assume theres fish in the tank?

I wouldn't attempt to use anything that would harm the fish,have you tried using a scrapper,the stanley blade type scraper used for windows,they're very good for scraping off hard deposits,then use a clean unused cloth to wipe it off,you can also buy scourers in lfs for tank glass...
