Can you use dishwasher salt to de-ice your driveway?

Where do we get KCl?

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!

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.

The pound shop had tubs of the path clearer in.

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.
