The main thing to take notice of is that once the temperatures get into the 40°’s and 30°’s all products take noticeably longer to dissolve graffiti.
Dwell times need to be 2-3 times longer to yield the same results, and it’s often helpful to leave product on much longer than that.
It helps to keep the product indoors and even inside the car so that the products are at room temperature when you apply them.
A hot water pressure washer/ steam cleaner helps a lot.
Sometimes it even helps to use them first to heat up a section of graffiti before removing it. You can also fill a bucket with hot water and leave the gallon of BB in the bucket to warm it up before applying it.
During the winter months we will sometimes apply Bare Brick Stone & Masonry Graffiti remover several times and then leave Transgel on over that which helps it stay wetter for longer and eats through all the thicker bits of graffiti as well as penetrating and dissolving from behind.
For signs, trucks, trailers, and other Sensitive Surfaces, you may need to leave Sensitive Surface Graffiti Remover on for several minutes before coming back to agitate and wipe away. Sometimes lightly abrading the surface with a soft scourer between coats will help the remover penetrate and begin dissolving it faster.
Pressure washing in freezing conditions tends to be problematic so generally things slow down on the East Coast until Spring.
Larger graffiti removal and coating projects are best left until the weather warms up.

3 Golden Rules
1) IF GRAFFITI IS NOT COMING OFF EASILY, YOU’RE DOING IT WRONG! You may require a change of tact or use of another product.
2) IF YOU CAN’T REMOVE A LITTLE BIT OF GRAFFITI, THEN YOU’RE NOT GOING TO REMOVE A LOT! TEST FIRST before applying product to an entire job. This way you can determine if you’re on the right track before embarking on full scale removals.
3) IF YOU’RE WORKING HARD, YOU’RE DOING IT WRONG! Forget the scrubbing, blasting and any other abrasive measures. Put simply, either your products are working or they’re not. Any problems can be taken care of with the right technique.
