Hi chaps , i have been doing a job restoring upvc back to looking new , now although i have done 9 flats so far with no probs i have 3 bottom flats with the cill which has turned yellow , now i have been using viro-sol at 25;1 ratio , then at about 12;1 ratio , but the yellow is still there . The tenants are fine with it but im not,as anyone got any other ideas , cheers in advance

Depends on the age of upvc forget viro-sol try trade solvents - Even then old upvc can be effected by Uv light ...deteriates no answer - new upvc has uv stabilizes hence not so bad still only guaranteed generally 10-15 yrs.

Unless I am badly mistaken this sounds like it has been caused by UV light and if it's the same as happens to white Epoxy grout there is no way to get it out that I know of on UPVC other than to rub it down and repolish.  If this is the case it's cheaper to fit new cills.

Hi

just this once why not bleach it out.

Done it myself in the past.

spray on detox mould and mildew remover and leave.

If you don't want to go the bleach route you can use T cut (yes it's abrasive) or even nail polish remover. If normal cleaners are not working you'll have to try other methods, try on a small bit first though.

Also try persil Bio or sugar soap.

virosol wont shift it .... i have used virosol for the past 2 years and know it wont.

Best thing you can try is doktor power which is a JML product  that i get from asda.
