have got an account that has there glass con roof cleaned every month.
Last time i cleaned it, there was loads of yellow/rust colour spots about 3 mm in diameter. these i believe are bee poo.
Whats the best way to get rid of them ? I tried pre soaking, in the end i had to soak and then get my bank card out and scrape then rince !!
There must be a better way
HELP !!!!!
