This product effectively and quickly dissolves and removes lime scale and mineral deposits from hot spring pools, boilers, solar hot water pipes, water dispensers, electric water bottles, and other water pipes or inner tanks.

Instructions for use:
1.Where water is circulating in the pipe, apply this product directly and keep the water circulating for about 30 ~ 60 minutes. Drain the pipe when the circulating water becomes milky white and muddy, rinse it with clear water and keep it circulating one or two more times.
2.Where water is not circulating in the pipe, pour clear water in to cover all the scale, and then directly apply this product; open all the outlets to let this product flow to the outlets and then close them (use PH test paper to confirm whether this product has flowed to the outlet since this product is acidic and the test paper will turn red), switch off the power supply, and leave it for 30 ~ 60 minutes. Then pour out or drain the waste water, and rinse the pipe or inner tank with clear water one or two times. In the case of thick lime scale, dissolved scale may block the pipeline, so be sure to occasionally open the outlet to check for blockage; if a blockage is found, first discharge any dissolved scale before proceeding.
3.When used in a small household water dispenser or electric water bottle, pour clear water in to cover all the scale and then directly apply this product (350 grams in all), switch on the power supply, and press the outlet handle to allow the product to flow through the outlet; then release the handle, switch off the power supply, and leave it for 30 ~ 60 minutes; finally, pour out or drain the waste water and rinse the pipe or inner tank with clear water one to two times.
4.This product can be used in its original solution or diluted with water, as long as it is still acidic after dilution, and the concentration is proportional to the scale dissolution rate; the higher the concentration, the faster the dissolution rate.
5.This product is a safe colorless and odorless organic matter and can be easily removed by rinsing with clear water. Its residue is completely harmless to the human body.
