Why has the concept disappeared from the scene?

What was the gel which was used?

[Franz Heymann]


The product in the UK was Fisons Clearcut.

The company spent a small fortune on advertising the product in various
media including TV, and it sold like hot cakes - but as soon as they
stopped advertising, it stopped selling...

It just wasn't profitable, and ISTR it had a restricted shelf-life,
which meant that Garden Centres and wholesalers didn't want to stock it
if it didn't turn over fast enough to avoid wastage.
