Above show the condition of the bathroom before applying Mr. Muscle. Ok, for a while there, I see high hope in getting rid of the stuborn stain. Read the instruction printed on it. Ok, time to rock & roll.
Apply Mr. Muscle. Waited few minutes. Rinse with clean water. What the heck?!
Stain still there? OK, perhaps I need to leave it over night. Spray Mr. Muscle on all those spots again. Leave it over night. We will see how it goes tomorrow.
