What recent reviews say

All five reviewers gave five stars. Work ranged from residential water tank cleaning (including 20-year-old systems with heavy rust buildup) to pool and swimming gala prep, with one customer returning to hire them for six office tanks. Pricing noted as reasonable.

Based on limited recent reviews, so treat this as low-confidence.

Yes. One reviewer had a 20-year-old tank with layers of rusty sludge from old Selangor piping; the business cleaned it, and the customer then hired them for six office tanks.
Can you service multiple tanks at once?

Older reviews praise leather care and furniture restoration at fair prices; recent positive feedback is sparse on detail. Evidence is thin and aged, with limited current insight into service quality or consistency.

Strong satisfaction with staff professionalism and work quality drives most feedback, especially for carpet and residential deep cleans. However, inconsistent execution on post-renovation jobs, incomplete repairs after damage, and disputes over cleaning scope have created doubt among some customers about whether the promise matches delivery.
