Finish Protector Diamond,Chachp, Rolls_rapide
Chachp, this is a crystallized chemical, I forget what exactly, meant to prevent glassware etching, it is contained in a perforated plastic clip on DW rack Finish stylized diamond case. I used it while it was available here in Vancouver Canada until it disappeared from store shelves about 2 years ago. Maybe pricing scared customers away or marketing was deficient, I think regular price was close to $10.,if IRC lasted 2-3 months and if it performed the job, and I have no doubt that it did, then really cheap in the end especially if you have soft water as we do. I think Pre-measured tabs or pods give too much detergent in modern DW's.
Rolls_rapide,what is your pricing in Scotland? Maybe I need to find an online source and import this glass protector, I feel it is a good idea.
