Handheld dish brushes are ideal for tough dried-on food residue and for cleaning pots. They are easy to hold, clean effectively, and last a long time. I keep mine clean by washing it in hot soapy water and sterilising it by placing it in a mug of boiling water. You could also use Milton tablets.

Sponges constitute the phylum Porifera, and have been defined as sessile metazoans (multicelled immobile animals) that have water intake and outlet openings connected by chambers lined with choanocytes, cells with whip-like flagella. [18] However, a few carnivorous sponges have lost these water flow systems and the choanocytes. [19] [20] All known living sponges can remold their bodies, as most types of their cells can move within their bodies and a few can change from one type to another. [20] [21]If you want to make the cake layers ahead of time, you can cool them completely, then wrap them tightly in plastic wrap and store them at room temp for up to a day before you frost them

Most sponges work rather like chimneys: they take in water at the bottom and eject it from the osculum ("little mouth") at the top. Since ambient currents are faster at the top, the suction effect that they produce by Bernoulli's principle does some of the work for free. Sponges can control the water flow by various combinations of wholly or partially closing the osculum and ostia (the intake pores) and varying the beat of the flagella, and may shut it down if there is a lot of sand or silt in the water. [21] Preheat the oven to 190°C/170°C fan/375°F/Gas 5. Grease and line 2 x 8” square loose-bottomed cake tins. Most known carnivorous sponges have completely lost the water flow system and choanocytes. However, the genus Chondrocladia uses a highly modified water flow system to inflate balloon-like structures that are used for capturing prey.

The calcium carbonate or silica spicules of most sponge genera make them too rough for most uses, but two genera, Hippospongia and Spongia, have soft, entirely fibrous skeletons. [127] Early Europeans used soft sponges for many purposes, including padding for helmets, portable drinking utensils and municipal water filters. Until the invention of synthetic sponges, they were used as cleaning tools, applicators for paints and ceramic glazes and discreet contraceptives. However, by the mid-20th century, overfishing brought both the animals and the industry close to extinction. [128]

Bamboo-based sponges – the pulp of the bamboo grass is spun into a textile which resembles a sponge. Read more here on bamboo sustainability. However, some manufacturers mix the compostable cellulose with less desirable and non-recyclable materials, therefore having a significant carbon impact. It also makes the could-be compostable sponges, now non-compostable. Biodegradable Sponges Codium fragile ssp. tomentosoides (Dead Man's Fingers).

Sponges have three asexual methods of reproduction: after fragmentation, by budding, and by producing gemmules. Fragments of sponges may be detached by currents or waves. They use the mobility of their pinacocytes and choanocytes and reshaping of the mesohyl to re-attach themselves to a suitable surface and then rebuild themselves as small but functional sponges over the course of several days. The same capabilities enable sponges that have been squeezed through a fine cloth to regenerate. [44] A sponge fragment can only regenerate if it contains both collencytes to produce mesohyl and archeocytes to produce all the other cell types. [34] A very few species reproduce by budding. [45]
