an auto-laundry soap that is so concentrated that you will use more water but less soap in the mixture. This way, your bottle will last for many washes, thereby allowing you to save money. So, you should aim for a soap with the lowest lather-to-water ratio.

Ingredients formulation

Generally, we recommend choosing a lather made from either mild or active surfactants. The presence of these compounds will ensure your soap mixes well into the H2O for ease of removing dirt from the surface.

You should also consider if the lather is both sulfate- and phosphate-gratuitous. because these two chemicals could strip your machine of its protective wax together with sealants.
