OCD GEL 1 LITRE ORIGINAL

Description

OCD Gel 1 Litre Original is a professional-grade detergent and degreaser concentrate specifically formulated for cleaning and decontaminating hydroponic equipment, growing containers, reservoirs, and grow room surfaces. We have been recommending OCD Gel to UK growers since 2017 as one of the most effective and versatile cleaning products for the grow room environment — it removes the mineral deposits, organic residues, nutrient staining, and biofilm accumulations that build up on equipment between grow cycles and create the ideal conditions for pathogen carryover.

Why OCD Gel Is the Right Cleaner for Hydroponic Equipment

Grow room equipment faces a specific set of contamination challenges that generic household cleaners are not formulated to address. Nutrient solutions leave mineral salt deposits — calcium carbonate scale, iron and manganese precipitates, and crystallised fertiliser residues — that bond strongly to surfaces and harbour pathogen organisms. Organic matter from root exudates, dead root tissue, and algae forms a biofilm that adheres tenaciously to reservoir walls, pump housings, and irrigation pipes. OCD Gel’s formulation combines alkaline degreasing agents with chelating compounds that lift and solubilise both mineral and organic deposits, removing them completely from surfaces rather than just dispersing them into the rinse water. The gel consistency provides extended contact time on vertical and overhead surfaces where liquid cleaners would run off before achieving full effectiveness, making it particularly useful for cleaning reservoir walls and the interior of large containers that cannot be easily inverted. OCD Gel rinses cleanly without leaving residues that could affect the next crop.

How to Use OCD Gel for Effective Grow Room Cleaning

Dilute OCD Gel according to label instructions — typically 5–10 ml per litre for general cleaning. Apply to surfaces using a brush, sponge, or spray bottle and allow to dwell for 5–15 minutes before scrubbing and rinsing. For heavy mineral scale, apply undiluted gel and extend the contact time to 30 minutes. Always rinse thoroughly with clean water after cleaning, particularly on surfaces that will contact nutrient solution. Follow the OCD Gel clean with a ROX or hydrogen peroxide sterilisation treatment for a complete decontamination protocol between grows. Wear gloves when handling concentrate.

Pair OCD Gel with ROX sterilisation solution for a two-stage grow room decontamination protocol: clean with OCD, then sterilise with ROX. Browse our full range of grow room cleaning and sterilisation products for comprehensive between-grow hygiene management.
