About the products
What does a GRIME LABS tablet actually do?
Each tablet is an effervescent cleaner that dissolves the hidden buildup inside an appliance — detergent residue, limescale, grease, biofilm, mineral scale — that regular detergents leave behind. It cleans the machine itself, not your laundry or your dishes.
How are GRIME LABS tablets different from competitors?
Each formula is designed for a specific appliance (washer, dishwasher, ice maker, jetted tub). No all-purpose compromises. Plus, every pack is a one-year supply, so you don't run out after a few weeks.
Are the tablets safe for septic systems?
Yes. All our formulas are septic-safe and EDTA-free.
Are the tablets safe for High Efficiency (HE) washers?
Yes. The washing machine tablets are low-foam and tested on front loaders and top loaders, HE and standard.
Are the tablets safe in hard water areas?
Yes — and they're especially effective in hard water, because they actively dissolve limescale.
How to use them
How do I use a tablet?
Drop one tablet into the empty appliance, run a normal hot cycle, done. No measuring, no liquids, no scrubbing.
How often should I use them?
Once a month for regular maintenance. Every 2-3 weeks if you have hard water, multiple pets, or use the appliance daily.
Can I add clothes or dishes to the cleaning cycle?
No. Always run an empty cycle — the tablet's job is to clean the machine, not your laundry or your dishes.
Can I use the dishwasher tablet in the washing machine (or vice versa)?
No. The formulas are tuned for different residues. Always use each tablet in the appliance it's labeled for.
