For initial application use undiluted.
For regular maintenance dilute 1:4, 1:10 or 1;15 as the job requires. Use a long handle brush to reach areas not so easily accessible such as under the lip of the toilet bowl and urinal tiles and surfaces. Brush well into the main outlet and grills of urinals. Apply daily to keep toilets clean.
Use of gloves while handling is recommended. Avoid skin contact
