Ask your Mom if she remembers this product!  It's been around since 1956, with millions of devoted fans.  It's the safest, most versatile cleaning product I know of. Highly concentrated means inexpensive to use.  Add the water yourself.

Put a 1/4 teaspoon in a spray bottle full of water and keep it on the counter for general cleaning. A bit more in a bucket of water tackles larger jobs.  I love that it's replaced so many of the dangerous cleaners we used to use, and saves money too!

This was named an original Earth Day product, and was the only cleaning product so honored.  It's completely biodegradable - ALL of the product returns to a natural state within 30 days, unlike some competing cleaners which only have biodegradable surfactants.
