    Where do we get KCl?

    Must be better for the environment!

    Must be better for the environment!

    Chemically very similar to NaCl (sodium chloride, aka common salt) but more expensive.

    What is better is calcium chloride, which works at a lower temperature than salt. Think its sold commercially in bulk called 'IceMelt'.

    Edit: a shovel is more environmentally friendly!
    For every complex problem there is an answer that is clear, simple and wrong.

    Depends on cat litter

    Some of it is made of paper, others clay

    Read in paper today, both salt and cat litter sales have increased

    My mum uses the ashes from the fire as well - must work since if you skid getting out of her driveway you're heading into the river... quite an encouragement not to screw it up.

    Fullers earth cat litter turns to a grey mud when wet and will be walked all over your house and you don't see it till it dries. I know bwcause I dropped a bag by accident in the summer and brushed it up but when it rained all the bits in the cracks stuck to shoes and got walked in.
