We have very hard water and a front-loader machine (ours goes up to 11 ;)). Â I've feel like I've tried everything to clean dipes at home, and have just found some solutions (thus far, anyway)!Â
Â
Ruby Moon detergent has been very effective for us - more so than Rockin Green. Â We use a full 3 tbsp per load. Â We also use some old towels to fill up the machine during wash to get enough of a "swish" factor to get them clean. Â I also use more hot water now. Â I do a full hot cycle with detergent, ANOTHER hot cycle with detergent, and then a full cold rinse. Â I deep clean & bleach once a month - deep cleaning by just soaking in Ruby Moon for an hour in hot water, putting in a tablespoon of bleach during the wash cycle, then rinsing and rinsing and rinsing.
Â
Calgon helps a lot, but I think it's really expensive and adds up fast, so I'll be trying the 2 tbsp of salt as a softener instead. Â
Â
Hope any of this helps - I understand your frustration :(.
