Its been a few weeks since I quoted a gym with red and blue carpet tiles. I thought I would be ok as I had a while to make sure I got the right chems est.
However, I am still not confident...

Most people say just use your HWE machine ' you will be fine'
but when i go on carpet tile cleaning on youtube or just using the net there is alot to do with bonnet cleaning and encap.
can someone just point out 'what is encap' why is it different to ust bonnet cleaning? can you encap with a normal low rpm bonnet machine?
If so.. what chems would you use, say if you were cleaning a carept tiles?
