Bluestone is a Vietnamese brand (Sunhouse Group) in the sub-10 million VND segment, suitable for families just starting to use dishwashers. For the machine to operate well, choosing the right detergent tablets, salt, and rinse aid is extremely important. This article provides detailed instructions.

3. Why does Bluestone need quality detergent tablets?
Common misconception: “If I buy a cheap machine, I should buy cheap tablets to match.” This is a big mistake:
- Cheaper machines → lower water pump/heating power → good tablets are essential to compensate.
- Cheap tablets produce excessive foam → machine doesn't rinse completely → easily damages the water circulation system.
- Regular table salt → damages the water softening system within 6-12 months.
Saving 100k VND on detergent tablets but spending 5 million VND on machine repair → not economical.
4. Largo dishwasher tablets for Bluestone machines
4.1. Optimal choice: Largo Classic
Largo Classic 60 tablets – 229,000 VND
Reason for suitability: Only 3,800 VND/tablet – less than the operating budget. EU quality, no excessive foam → safe for Bluestone machines. Combined with sufficient salt and rinse aid = dishes as clean as with expensive machines.
4.2. Upgrade option: Largo All In One
Largo All In One 40 tablets – 219,000 VND
Suitable for those who want convenience and don't want to add separate rinse aid regularly.
5. Dishwasher salt for Bluestone
→ Largo German Salt 2kg – 175,000 VND
Important note: Even with inexpensive machines, the water softening system is still very "fragile" when using poor quality salt. Replacing the ion exchange resin system costs 2-3 million VND – almost the price of the machine. Use Largo NaCl pure 99.9% salt to protect your machine.
6. Rinse aid for Bluestone
Bluestone has an average drying index → needs rinse aid for optimal results.
→ Largo Rinse Aid 1000ml – 189,000 VND
Lasts ~6 months → more economical than cheap imported rinse aids (which usually only last 2-3 months).
7. “Bluestone Basic” Combo
→ Largo Combo of 3 – 555,000 VND
EU-standard operating cost for Bluestone machines: Lasts 2-3 months → ~185,000 VND/month for a family of 4. Cheaper than dish soap + scrubbing pads for hand washing. Protects the machine, extends its lifespan by 5+ years.
8. Tips for effective Bluestone use
- Use “Auto” for the machine to automatically select the temperature.
- Clean the filter screen weekly.
- Once a month: run “Self-Clean” with 1 Largo tablet to clean the interior.
- Unlike German machines, Bluestone doesn't provide clear warnings → check salt and rinse aid every 2 weeks.
9. Conclusion
The idea of “cheap machine, cheap tablets” is an economic fallacy. Bluestone needs quality detergent tablets for long-lasting performance. Largo imported from Germany at a good price is the most harmonious choice.
