Do Colour catcher sheets actually work?

Colour catcher sheets can cause your machine to stop draining

Whites and colours washed separately Traditionally, the approach to laundering your whites and your colours is to wash them separately, because coloured dyes can be released during a wash and transfer to other items in the laundry. Also, whites and colours laundry require different types of detergents; whites require Oxygen bleach to stay bright, whereas colours require a detergent without oxygen bleach to prevent fading. Colour catcher sheets Colour catcher sheets are advertised as a way to wash mixed loads of whites and colours together safely. The sheets are designed to act like a magnet or a sponge; they’re treated with special ionic polymers to absorb loose dye released during washing and apparently prevent it from transferring to other items in your laundry. We're not convinced putting a Colour catcher sheet in a washing machine will be actually doing anything, the sheets seem to change colour - but that isn't necessarily going to prevent colours running since the colour dyes will also be accumulating in the water elsewhere in the washing machine.

Using Colour catcher sheets can cause

your washing machine to stop draining

The sheets are small enough to slip through the gap between the inner drum and the door seal during a wash. Once inside, they can block the sump hose and the pump filter, severely restricting the machines ability to drain. Our Advice: Don't waste your money buying them; we're not convinced they’re actually doing anything at all - other than they’ll end up costing you a visit from us to remove them from your washing machine.
