Cascade Platinum is my favourite dishwasher detergent. I’ve been using it for years (https://cascadeclean.com/en-us/products/cascade-platinum-actionpacs-dishwasher-detergent-fresh-scent/)
In the last week, my local costco warehouse and costco.ca stopped providing Cascade Platinum. Instead, they’re still selling Cascade Power Clean in green box (https://www.costco.ca/cascade-power-clean-dishwasher-detergent-actionpacs%2C-115-count.product.100483144.html) and they added a new product to the shelf Cascade Platinum Plus (https://www.costco.ca/cascade-platinum-plus-actionpacs%2C-81-count.product.4000230558.html)
I’ve tried the power green one, and I’m not satisfy with its quality: the smell of the food may remain in my dishwasher. The Platinum Plus is much more expensive than Platinum.
Does Costco changed the product line at your warehouse?
Stuff disappears and comes back all the time at my store. I don’t know how it is in Canada, but sometimes the management after the cash registers can say if something’s temporary or been discontinued by looking in the inventory system. Often they don’t know, though.
