Info: 12 Sponge Types Available; Colours Vary
BioBob sponges have been handmade in Ontario for over 50 years using organic pigments and an 'enviro-ester' formulation that's free of formaldehyde and CFCs. These sponges with a micro-pore technology are both durable and a pleasure to work with.
Biobob sponges are soft; they won't harm even glossy, fine or delicate finishes; they float; they're quite absorbent (except for the two scrubbers 'Ned' and 'Tub Tuffy'); their effectiveness improves with use, after each time you wring them out; they can be machine washed (in hot water up to 212F) and dried; they won't smell or harden after you've rinsed them, because they're cellulose free (sponges that harden are made of wood, which feeds bacteria when it gets wet); and they can last for years.
Sponges certainly have their uses for a number of household cleaning and mopping up tasks, but they can be a bit of an environmental minefield, both within the house, if they wind up souring and outside, from their disposal. Not BioBob sponges -- they all have a one year warranty from the company (except for the Tub Tuffy and Derma-Luxe types); and they're not only biodegradable, but bio-reusable, since you can dispose of them by cutting them into pieces that are great to use in potting soil.
Please note: since these sponges are artisanally made and each one differs a little, the sizes may vary from the dimensions listed below. Also, each type comes in various colours, not just the ones shown.
#3 Non-Stick Ned
A small (about 4-1/4 x 2 x 3/4 inch) scrubber which works very well with baking soda or cleaning pastes which can be used safely on all surfaces: even fiberglass and shiny plastic. Great for ceramic surfaces like stove tops.
#4 Tub Tuffy
A larger version (nearly 5 x 3 x 1 inch) of the above; great for cleaning tubs, tiles and sinks with either baking soda or your favorite liquid cleanser.
#5 The Cute One
The dimensions of this hand-sized sponge vary quite a bit: basically, it's whatever they can squeeze into a 6 by 4 inch Ziploc-style bag. Some are thinner, and are good for applying cleaning pastes onto your vehicle or creams or pastes onto shoes or other leather; some are thicker (e.g. one is a little over 4 x 2.5 x 1-3/8") which could be used either for doing dishes or as a travel-sized bath body sponge.
#6 BC Derma-Luxe
These rectangular-shaped Body Cloths are designed for washing yourself in the shower with either soap (simply rub on your bar of soap, fold the sponge, and rub on more, to be able to produce maximum bubble power) or a shower gel (same directions, but use less than normal). Their surface is about 6-1/4 by 4-1/4 inches -- about the size of many paperback book covers -- and most are a little over 1/4 inches deep. They have a finger-sized hole in one corner to hang them to dry.
Somewhat larger than a puck (3-1/2" diameter by 1-3/8"), these palm-sized sponges could be your go-to kitchen helper for wiping up small spills, or a favourite of your children in the tub, or used for applying shoe polish.
#6 Hand Size
This thick rectangular sponge with rounded corners on the top is a familiar size for a sponge: about 5 x 3 x 1-3/8". Some use it as a body sponge in the bathtub, others for cleaning dishes or other items; and it's also large enough to tackle jobs like applying saddle soap or beeswax cream to leather furniture.
#7 Counter Buddy
This one is also rectangular with rounded edges on top, but is a little thinner and has slightly more surface than the #6 (at 5-1/4 x 3-1/4 x 1-1/4 inches), making it still thick enough to be able to wipe up big spills, but thin enough to wring out and break in quicker, so in addition to doing dishes and wiping up your counters with it, it's really good for dusting, cleaning crumbs, or wiping various types of shelving, or wiping grime off windows.
#7E Elongated Dishes & Deep Glasses Sponge
Like the name says, this fairly long, relatively narrow (6-1/2 x 2-1/2 x 1-1/4") sponge was designed especially for handwashing deep glasses or other dishes which you have difficulty reaching into with just your hand and a dishcloth. Even if the dish is deeper than the sponge, its originator reports you can just swish it around and fish it out with the end of a rubber spatula or wooden spoon.
#9 Wall & Floor
For those really big cleaning jobs, you want something with a big surface that's not too hard to wring out and doesn't dribble down your arm when cleaning a ceiling or wall, so this 7-1/2 by 4-1/2 by 1 inch rectangular sponge does the trick nicely
#10XL Extra Large Car & Truck
If you're cleaning a big car, truck, or boat and want to be able to scoop up plenty of soapy water and apply it over large areas at once to make short work of it, this is the one for you. At 7-1/2 x 4-1/2 x 2 inches, this dictionary-sized brick can hold up to 2 pounds of liquid! By the same token, after it's been worked in and wrung out a number of times, it can also absorb plenty of water, so you can use it for mopping up major spills or leaks, as well.
Turtleback sponges are rectangular and flat on the bottom and arch up on two sides to a smaller surfaced top, so the dimensions here are a little over 6 inches by over 3-1/2 on the bottom by about 3-1/2 inches square on top for a solid grip, by about 2 inches deep. People use turtleback sponges for sponge painting, or wallpaper cleaning or car cleaning, among other things.
Not to be used with paint thinner or nail polish remover, as they act as solvents to the polyester, thus voiding the 1 year warranty which most of these types come with (all but the Tub Tuffy and Derma-Luxe Body Cloth types).
