Easy-Open Resealable Tub

Pro-Kleen's easy to use, resealable tub makes it easy to close after use and conveniently reseals for optimum freshness.

How to Use

Simply refer to the suggested usage on the reverse of the tub, dissolve your chosen amount of solution into water and apply via watering can or sprayer onto your grass.

Grass Greening

Mix 1-2g of Iron Sulphate per 1L of water. 1L of the solution will cover 1m² of grass.

Turf Hardening

Increase the concentration and not only will it have an amazing effect on the greenness of your grass but it will also start to ‘harden’ the turf making it more resistant to disease and fungal attack. This makes it a very common practice on sports turf in autumn and winter. For hardening, we recommend applying between September and April when plenty of moisture is available and when sunshine is unlikely.

Mix 2-3g of Iron Sulphate per 1L of water. 1L of the solution will cover 1m² of grass.

Please ensure you do not use Iron Sulphate products on hard surfaces as this can cause staining
