"Not in the politicians' or BBC's definition. but in the proper definition. It is nothing special, you don't notice it, it just gets on with the job and I have nice clean brushes (and floor). Three stars for value because the same product at one pound cheaper was 'out of stock' at all local depots."
"I use this mainly as a brush & roller cleaner when using oil based gloss paint & occasionally to clear the last traces of dust from a surface prior to painting. It's a good strong solvent that removes even semi dry paint quickly, bonus is it's cheap. Nice sturdy container with the usual 'child proof' cap. Can't fault the product."
