fernox cental heating protect

"Grear value. Bought on deal of the day. Read the reviews. The description does not tell of the amount of radiators it will treat, the answer is up to ten. If as above that as i do you will need two bottles. The assistant at screwfix was very helpful to aquire that info. for me. What a great team."
