There's rust on an SMC shower tray (left from cans left on surface). Rust marks not removed by baking soda, Jif or 30 Seconds rust remover.
The manufacturer has apparently suggested trying Domestos level 8 corrosive in a blue bottle. I'm pretty certain bleach is a bad idea.
Does anyone have any other ideas? thanks
