URID is safe to use, because it contains no strong, corrosive mineral acids. URID's penetrating chelate dissolves and releases the mineral bonding agents that cause adherent scale.
DIRECTIONS FOR USE:
URID may be used as a dip or spray in a dilution of 1
to 3 or less with water depending on scale buildup. After a few minutes,
cages or pans are ready for regular wash treatment.
URID can be used for cleaning cages and trays in mechanical cage washers. For light urine scale deposits use URID at a dilution of one-half ounce per gallon (0.4% solution). For heavy deposits of urine scale, use URID at a dilution of one ounce per gallon (0.8%).
