I have many commercial customers with fresh and old coffee stains. Most of the time i use Dynamall and it works great.  But some stains are realy stubborn and i need a special browning treatment.

Today i cleanend a office with 190 sq/metres. The result was great....the carpet has never been cleaned.... But they have had three huge coffee stains i coud only lighten up.... I wasn't satisfied.

How do you handle these brown/ yellow stains and what product do you use and what is your process?

Whichproduct do you recommend? I have read about Prochem Browning Prescription and  Chemspec Browning Treatment...

I used chemspec superbrown attaches to the felidamide bonds to really lighten browning. Prochems browny combines well with an acid rinse as this releases kilot  molecular biology  to reduce spoiling.

But the best stuff is Trevor greens brown be gone. It literally removes all brown marks in one pass like a sheet of Andrex double velvet across a recent excretion.

Hope this helps
