What to do if there is a black strip stain in the toilet

The yellowing of the outside of the toilet refers to the gap between the toilet shell or the toilet base and the ground, if the toilet shell is yellow, this can be removed with toilet cleaner; If the gap between the toilet base and the ground is yellow, because this gap is generally made of adhesive glue, this means that the adhesive may be too long to fail, with the phenomenon of local water seepage, this needs to remove the toilet, clean up the stains in the base, and then re-install the toilet, and lay the adhesive (the toilet can not be used for at least 24 hours after gluing).

If you can't clean it after soaking in ordinary toilet cleaner, try all-purpose water.

I believe that the evaluation criteria of green buildings are multifaceted, including building energy conservation (water saving, land saving, electricity connection, material saving), environmental factors (indoor environment, outdoor environment), construction factors (energy saving, noise reduction, safety, etc.), later operation management (humanities, green, health), innovation (material, technology, management innovation, etc.).
