We launched 40shot, born out of a genuine love of motorhoming shared across the Qualkem team. We kept seeing the same frustrating problem: users had to measure out chemicals for their cassette toilets with messy measuring cups, spilling blue dye everywhere and wasting product in the process.
15 years ago, we solved that problem for good with our unique built-in dosing system, no measuring, no mess, no waste. We added real value with 40 doses per bottle, and that's exactly where the name comes from.
Fast forward to 2026, and 40shot is a nationally recognised brand leading the market. We're incredibly proud of what it's become, and now you can order it directly from us at shop.qualkem.co.uk.
