This is a chemical that has been around for some time now, its a chemical that does the job every time as we dont use anything else really. The packaging gets top marks as can carry the boxes well, the spray can itself is usually a yellow transparent can and can easily see the contents in it. The chemical is easy to pour, mixes well, there is sometimes a settling in bottom but this rinses out easy enough its not a problem. Overall if all other chems was like cycocel the job would be much easier!! Well done basf
