how to clean grease box

WELL GUYS, I DID THIS PROCEDURE WHEN AFTER 3 YEARS LIVING IN MY HOUSE, I REMEMBERED THE FAT BOX. WHEN I LOOKED AT THE LAYER IT WAS GREATER THAN 10 CM. MY SUFFERING. THAT'S WHILE SHE TOLD ME ABOUT THE LIME. I BUY IT AT THE TIME AND POUR IT INTO THE BOX. IT BEGAN TO REACT WITH THE FAT. THEN THE MIXTURE WAS DISSOLVED ALMOST LIQUID.
THE LIME RESIDUE THAT STAYS AT THE BOTTOM OF THE VC BOX CAN BE REMOVED BY PUTTING THAT WASHING MACHINE'S REUSE WATER. SO IT GOES ON TO THE SEWAGE.THE BEST WAY FOR QUICK AND EASY CLEANING OF THE FAT BOX I FOUND WAS THIS.SO THAT'S IT, GUYS.
