This Vegan Zero Waste Dish Washing Block by No Tox Life has everything you are after and at 213 grams (or 7.5 oz as the Americans put it) this product will last many months.
This is a cleaning powerhouse with a rich, sudsy lather. It cuts stubborn grime and grease on dishes, pots and pans and with added aloe vera it is also gentle on your hands. Added bonus, its is also palm oil-free, cruelty-free, sls-free, phosphate-free and fragrance-free.
You can even use it for cleaning-duty all over your home. Take stains out of laundry, take labels off of jars, spot clean your carpet, use it to wipe down counters... it's a truly multipurpose product.
To use, scrape dishes to remove excess grease and food. Wet sponge, for plates, bowls and cups, and rub dish block™ soap to create suds. (Repeat as needed to refresh suds.) Wash items and rinse well. Works in warm or cold water. We prefer warm water for best results. For pots and pans, use a scrubber or scourer.
Please note that using a strong scourer exclusively on the block will wear it down faster than using a soft sponge.
