has anyone ever used these on their tanks? i have one of the mag cleaners but that cant get off all of it so for the harder stuff i use a razor blade now. i seen that they have a red one and a yellow one. the yellow one is metal and the red one is plastic. has anyone ever used the red ones? do they clean just as well as the metal ones and do the metal ones actually scratch glass?
thanks
