I have recently made the decision to stop using fabric conditioner and those scent pearls on our laundry.
I believe fabric conditioner over time causes build up and damages the fabrics and also causes build up and gunk in the machine draw and pipes ( a washer guy from Hotpoint said this )
The scent pearls just add an overpowering floral fragrance and fragrance doesn't mean it's clean as clean doesn't smell of anything.
My routine is just Ariel pods or liquid and that's it and our clothes are clean but I just question AIBU to only use detergent and nothing else?
