Peletty Refill 1L Quality Guarantee Period: August 2026 This is a great value refill eco-pack, a "must-buy for repeat customers"! Please use it by refilling the "Peletty 500ml" spray bottle, which has special processing to prevent product deterioration. We received feedback saying, "I can't use it all because of the large capacity," but it can also be used as a disinfectant and deodorizer for purposes other than pets. (Toilets, tables, sofas, around trash cans, etc.) General hypochlorous acid water deteriorates quickly, resulting in a short usage period, but Peletty uses long-term stable sodium hypochlorite as a raw material and has the characteristic of not deteriorating in quality for 6 months after opening and 2 years when unopened.
