Calculates the pH based on the amount of sodium hydroxide used.
(Please see below for instructions on how to use it.)
・The standard water capacity for front-loading washing machines is 20 liters.
・According to the Soap Encyclopedia website, a pH of 9.0–10.5 is ideal for laundry, so 60g is the standard amount to use.
・It can also be used in dishwashers. For dishwashers, 30g should be sufficient? (Currently testing)

Sodium hydroxide is a highly toxic substance. It’s dangerous if you don’t have a background in chemistry, so please don’t try this at home...
That said, we do handle a 4% aqueous solution in 6th-grade science experiments (albeit under controlled conditions). Haha!
[Instructions for Use]
・Calculate the total amount of sodium hydroxide based on the combined weight of the solid and the solution.
・The solid amount is used for calculations when preparing a stock solution (concentrated solution). Please set the solution amount to 0 when using it. For safety reasons, a concentration of about 0.5% is appropriate.
・Pour the prepared 0.5% stock solution into the washing machine for use. When calculating the amount of solution to add, please set the solid amount to 0.
