I was sent a sample of this to try as i have yet to find a chemical that i am satisfied with for bonnet cleaning, i found the results to be fairly good but the dilution rates that are specified on the product say are 4/1 i found myself using about £10 of chemical on a £180 job ! it says make up your prespray and solution in ringer bucket to this dilution rate job which i think is very expensive compared to other products i use, 5litres of this cost about £27.
Am i missing something if this product was giving me results that were unique then maybe it would be worth it but i am far from trying all the bonnet chemicals out there, pureclean is next as that is more economical.
