id say its very similar to alltec citrus prespray , cleansmart orange x , if so i could use it 95 % of the time , both as a prespray and a spotter in more conc spray 👍. Cheers. .
Champion ? never used it , but its got sodium hydroxide to rack up the PH high , less of a general use prespray than the first one .
Definitely give Restormate Citrus Prespray a try it’s a really good product. It’s pH 9 but very effective and versatile, it works like a high pH prespray. I now use it on nearly all carpets and upholstery it saves carrying lots of different bottles of chemicals.
