KH-7 Oxy Effect Stain Remover

KH-7 Oxy Effect is a stain-removing laundry spray manufactured by KH Lloreda S.A., a prominent Spanish family-owned company headquartered in Canovelles (Barcelona), Spain.

The KH-7 brand was developed in the late 1970s by Jaume Lloreda, originally formulating cleaning solutions for his jewelry coating workshop. Recognizing its versatility and effectiveness, the company transitioned entirely into producing household cleaning chemicals and launched KH-7 across Spain. Today, the company remains 100% Spanish and independently owned by the Lloreda family, with manufacturing carried out at its facilities in Catalonia.
